Objective To determine the sensitivity and specificity of hyperglycosylated hCG (hhCG) measurements for the diagnosis of clinical pregnancies in the IVF setting and how soon post embryo transfer (ET) a pregnancy can be detected using an ultrasensitive (hhC

Purpose: Multifetal gestation (MFG) is much more common in pregnancies that utilize assisted reproductive technologies (ART). We assessed how these rates have changed over the previous decade and the impact on live birth rates (LBR)., Methods: This retrospective cohort study uses the National Summary Reports of the Society for Assisted Reproductive Technology (SART) from 2014 to 2020. Data points included only autologous cycles. The data were divided into five age groups as reported in the database: < 35, 35-37, 38-40, 41-42, and > 42 years old. Descriptive statistics and a two-tailed T-test were used to determine the trends and statistical significance (p < 0.05)., Results: Rates of twin births decreased substantially from 2014 to 2020 for autologous embryo transfers across all age groups and diagnoses. Surprisingly, the overall LBR for autologous IVF cycles decreased at similar rates from 2014 to 2020 in all age groups. The mean number of embryos transferred has dramatically reduced, especially across age groups < 42., Conclusion: Rates of twin and higher-level gestations have decreased substantially over the past decade; the effect correlates with the increased utilization of eSET and PGT. The cause of infertility did not significantly impact the rate of MFG., (© 2024. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Study Question: Is there an association between fertility status, method of conception and the risks of birth defects and childhood cancer?, Summary Answer: The risk of childhood cancer had two independent components: (i) method of conception and (ii) presence, type and number of birth defects., What Is Known Already: The rarity of the co-occurrence of birth defects, cancer and ART makes studying their association challenging. Prior studies have indicated that infertility and ART are associated with an increased risk of birth defects or cancer but have been limited by small sample size and inadequate statistical power, failure to adjust for or include plurality, differences in definitions and/or methods of ascertainment, lack of information on ART treatment parameters or study periods spanning decades resulting in a substantial historical bias as ART techniques have improved., Study Design, Size, Duration: This was a population-based cohort study linking ART cycles reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) from 1 January 2004 to 31 December 2017 that resulted in live births in 2004-2018 in Massachusetts and North Carolina and live births in 2004-2017 in Texas and New York. A 10:1 sample of non-ART births were chosen within the same time period as the ART birth. Non-ART siblings were identified through the ART mother's information. Children from non-ART births were classified as being born to women who conceived with ovulation induction or IUI (OI/IUI) when there was an indication of infertility treatment on the birth certificate, and the woman did not link to the SART CORS; all others were classified as being naturally conceived., Participants/materials, Setting, Methods: The study population included 165 125 ART children, 31 524 non-ART siblings, 12 451 children born to OI/IUI-treated women and 1 353 440 naturally conceived children. All study children were linked to their respective State birth defect registries to identify major defects diagnosed within the first year of life. We classified children with major defects as either chromosomal (i.e. presence of a chromosomal defect with or without any other major defect) or nonchromosomal (i.e. presence of a major defect but having no chromosomal defect), or all major defects (chromosomal and nonchromosomal), and calculated rates per 1000 children. Logistic regression models were used to generate adjusted odds ratios (AORs) and 95% CIs of the risk of birth defects by conception group (OI/IUI, non-ART sibling and ART by oocyte source and embryo state) with naturally conceived children as the reference, adjusted for paternal and maternal ages; maternal race and ethnicity, education, BMI, parity, diabetes, hypertension; and for plurality, infant sex and State and year of birth. All study children were also linked to their respective State cancer registries. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% CIs of cancer by birth defect status (including presence of a defect, type and number of defects), and conception group., Main Results and the Role of Chance: A total of 29 571 singleton children (2.0%) and 3753 twin children (3.5%) had a major birth defect (chromosomal or nonchromosomal). Children conceived with ART from autologous oocytes had increased risks for nonchromosomal defects, including blastogenesis, cardiovascular, gastrointestinal and, for males only, genitourinary defects, with AORs ranging from 1.22 to 1.85; children in the autologous-fresh group also had increased risks for musculoskeletal (AOR 1.28, 95% CI 1.13, 1.45) and orofacial defects (AOR 1.40, 95% CI 1.17, 1.68). Within the donor oocyte group, the children conceived from fresh embryos did not have increased risks in any birth defect category, whereas children conceived from thawed embryos had increased risks for nonchromosomal defects (AOR 1.20, 95% CI 1.03, 1.40) and blastogenesis defects (AOR 1.74, 95% CI 1.14, 2.65). The risk of cancer was increased among ART children in the autologous-fresh group (HR 1.31, 95% CI 1.08, 1.59) and non-ART siblings (1.34, 95% CI 1.02, 1.76). The risk of leukemia was increased among children in the OI/IUI group (HR 2.15, 95% CI 1.04, 4.47) and non-ART siblings (HR 1.63, 95% CI 1.02, 2.61). The risk of central nervous system tumors was increased among ART children in the autologous-fresh group (HR 1.68, 95% CI 1.14, 2.48), donor-fresh group (HR 2.57, 95% CI 1.04, 6.32) and non-ART siblings (HR 1.84, 95% CI 1.12, 3.03). ART children in the autologous-fresh group were also at increased risk for solid tumors (HR 1.39, 95% CI 1.09, 1.77). A total of 127 children had both major birth defects and cancer, of which 53 children (42%) had leukemia. The risk of cancer had two independent components: (i) method of conception (described above) and (ii) presence, type and number of birth defects. The presence of nonchromosomal defects increased the cancer risk, greater for two or more defects versus one defect, for all cancers and each type evaluated. The presence of chromosomal defects was strongly associated with cancer risk (HR 8.70 for all cancers and HR 21.90 for leukemia), further elevated in the presence of both chromosomal and nonchromosomal defects (HR 21.29 for all cancers, HR 64.83 for leukemia and HR 4.71 for embryonal tumors). Among the 83 946 children born from ART in the USA in 2019 compared to their naturally conceived counterparts, these risks translate into an estimated excess of 761 children with major birth defects, 31 children with cancer and 11 children with both major birth defects and cancer., Limitations, Reasons for Caution: In the SART CORS database, it was not possible to differentiate method of embryo freezing (slow freezing versus vitrification), and data on ICSI were only available in the fresh embryo ART group. In the OI/IUI group, it was not possible to differentiate type of non-ART treatment utilized, and in both the ART and OI/IUI groups, data were unavailable on duration of infertility. Since OI/IUI is underreported on the birth certificate, some OI/IUI children were likely included among the naturally conceived children, which will decrease the difference between all the groups and the naturally conceived children., Wider Implications of the Findings: The use of ART is associated with increased risks of major nonchromosomal birth defects. The presence of birth defects is associated with greater risks for cancer, which adds to the baseline risk in the ART group. Although this study does not show causality, these findings indicate that children conceived with ART, non-ART siblings, and all children with birth defects should be monitored more closely for the subsequent development of cancer., Study Funding/competing Interest(s): This project was supported by grant R01 HD084377 from the National Institute of Child Health and Human Development.

Objective: To develop in vitro fertilization (IVF) prediction models to estimate the individualized chance of cumulative live birth at two time points: pretreatment (i.e., before starting the first complete cycle of IVF) and posttreatment (i.e., before starting the second complete cycle of IVF in those couples whose first complete cycle was unsuccessful)., Design: Population-based cohort study., Setting: National data from the Society for Assisted Reproductive Technology (SART) Clinic Outcome Reporting System., Patient(s): Based on 88,614 women who commenced IVF treatment using their own eggs and partner's sperm in SART member clinics., Intervention(s): Not applicable., Main Outcome Measure(s): The pretreatment model estimated the cumulative chance of a live birth over a maximum of three complete cycles of IVF, whereas the posttreatment model did so over the second and third complete cycles. One complete cycle included all fresh and frozen embryo transfers resulting from one episode of ovarian stimulation. We considered the first live birth episode, including singletons and multiple births., Result(s): Pretreatment predictors included woman's age (35 years vs. 25 years, adjusted odds ratio 0.69, 95% confidence interval 0.66-0.73) and body mass index (35 kg/m 2 vs. 25 kg/m 2 , adjusted odds ratio 0.75, 95% confidence interval 0.72-0.78). The posttreatment model additionally included the number of eggs from the first complete cycle (15 vs. 9 eggs, adjusted odds ratio 1.10, 95% confidence interval 1.03-1.18). According to the pretreatment model, a nulliparous woman aged 34 years with a body mass index of 23.3 kg/m 2 , male partner infertility, and an antimüllerian hormone level of 3 ng/mL has a 61.7% chance of having a live birth over her first complete cycle of IVF (and a cumulative chance over three complete cycles of 88.8%). If a live birth is not achieved, according to the posttreatment model, her chance of having a live birth over the second complete cycle 1 year later (age 35 years, number of eggs 7) is 42.9%. The C-statistic for all models was between 0.71 and 0.73., Conclusion(s): The focus of previous IVF prediction models based on US data has been cumulative live birth excluding cycles involving frozen embryos. These novel prediction models provide clinically relevant estimates that could help clinicians and couples plan IVF treatment at different points in time., (Copyright © 2021 American Society for Reproductive Medicine.

Treatment of infertility has evolved as understanding of reproduction has improved. Fertility promoting surgery still is performed and recent advances have broken new ground. Hormonal treatments to correct gonadal dysfunction have been developed, but multiple gestation continues to be a significant complication. Assisted reproductive technologies have improved such that in vitro fertilization and its variants increasingly are used to treat nearly all causes of infertility. Advances in assisted reproduction are of 2 types: (1) incremental optimization of existing techniques and (2) development of new, disruptive technologies. Artificial intelligence and stem cell technologies are poised to have impact in the near future., Competing Interests: Disclosure The author has no commercial or financial conflicts of interest., (Copyright © 2021 Elsevier Inc.

Background: Randomized trials of assisted reproductive technology (ART) have been designed for outcomes of clinical pregnancy or live birth and have not been powered for obstetric outcomes such as preeclampsia, critical for maternal and fetal health. ART increasingly involves frozen embryo transfer (FET). Although there are advantages of FET, multiple studies have shown that risk of preeclampsia is increased with FET compared with fresh embryo transfer, and the reason for this difference is not clear. NatPro will compare the proportion of preeclampsia between two commonly used protocols for FET,modified natural and programmed cycle., Methods: In this two-arm, parallel-group, multi-center randomized trial, NatPro will randomize 788 women to either modified natural or programmed FET and follow them for up to three FET cycles. Primary outcome will be the proportion of preeclampsia in women with a viable pregnancy assigned to a modified natural cycle FET (corpus luteum present) protocol compared to the proportion of preeclampsia in pregnant women assigned to a programmed FET (corpus luteum absent) protocol. Secondary outcomes will compare the proportion of live births and the proportion of preeclampsia with severe features between the protocols., Conclusion: This study has a potential significant impact on millions of women who pursue ART to build their families. NatPro is designed to provide clinically relevant guidance to inform patients and clinicians regarding maternal risk with programmed and modified natural cycle FET protocols. This study will also provide accurate point estimates regarding the likelihood of live birth with programmed and modified natural cycle FET., Trial Registration: ClinicalTrials.gov NCT04551807 .

Purpose: To compare academic achievement in reading and mathematics at the end of sixth grade and progress from third to sixth grade by children conceived with in vitro fertilization (IVF) to those conceived naturally., Methods: This was a retrospective population-based cohort study of IVF-conceived singleton and twin children who took the 3rd grade and 6th grade public school standardized reading and mathematics testing in Texas., Results: There were 6623 children with reading scores in both the third and sixth grades and 6374 children with mathematics scores in both the third and sixth grades. Mean (± SE) scaled test scores for IVF and control singleton children for reading were 1544.6 ± 3.4 and 1527.7 ± 1.9, respectively, in third grade and 1701.2 ± 3.6 and 1681.0 ± 2.0, respectively, in sixth grade; for mathematics, the scores were 1564.4 ± 3.7 and 1548.9 ± 2.1, respectively, in third grade and 1774.0 ± 4.2 and 1752.0 ± 2.3, respectively, in sixth grade. In multivariate models, singleton IVF children scored significantly higher than control children in reading and mathematics, averaging 17.7 ± 4.0 points and 20.1 ± 4.1 points higher, respectively, in reading in third and sixth grades and 17.8 ± 4.4 points and 25.0 ± 4.8 points higher, respectively, in mathematics in third and sixth grades., Conclusions: Children conceived with IVF and aged 8-9 years and aged 10-12 years performed as well on third and sixth grade reading and mathematics assessments as their counterparts conceived naturally.

Purpose: Excess embryos transferred (ET) (> plurality at birth) and fetal heartbeats (FHB) at 6 weeks' gestation are associated with reductions in birthweight and gestation, but prior studies have been limited by small sample sizes and limited IVF data. This analysis evaluated associations between excess ET, excess FHB, and adverse perinatal outcomes, including the risk of nonchromosomal birth defects., Methods: Live births conceived via IVF from Massachusetts, New York, North Carolina, and Texas included 138,435 children born 2004-2013 (Texas), 2004-2016 (Massachusetts and North Carolina), and 2004-2017 (New York) were classified by ET and FHB. Major birth defects were reported by statewide registries within the first year of life. Logistic regression was used to estimate adjusted odds ratios (AORs) and 95% CIs of the risks of a major nonchromosomal birth defect, small-for-gestational age birthweight (SGA), low birthweight (LBW), and preterm birth (≤36 weeks), by excess ET, and excess ET + excess FHB, by plurality at birth (singletons and twins)., Results: In singletons with [2 ET, FHB =1] and [≥3 ET, FHB=1], risks [AOR (95% CI)] were increased, respectively, for major nonchromosomal birth defects [1.13 (1.00-1.27) and 1.18 (1.00-1.38)], SGA [1.10 (1.03-1.17) and 1.15 (1.05-1.26)], LBW [1.09 (1.02-1.13) and 1.17 (1.07-1.27)], and preterm birth [1.06 (1.00-1.12) and 1.14 (1.06-1.23)]. With excess ET + excess FHB, risks of all adverse outcomes except major nonchromosomal birth defects increased further for both singletons and twins., Conclusion: Excess embryos transferred are associated with increased risks for nonchromosomal birth defects, reduced birthweight, and prematurity in IVF-conceived births.

Study Question: What is the association between ART conception and treatment parameters and the risk of birth defects?, Summary Answer: Compared to naturally conceived singleton infants, the risk of a major nonchromosomal defect among ART singletons conceived with autologous oocytes and fresh embryos without use of ICSI was increased by 18%, with increases of 42% and 30% for use of ICSI with and without male factor diagnosis, respectively., What Is Known Already: Prior studies have indicated that infertility and ART are associated with an increased risk of birth defects but have been limited by small sample size and inadequate statistical power, failure to differentiate results by plurality, differences in birth defect definitions and methods of ascertainment, lack of information on ART treatment parameters or study periods spanning decades resulting in a substantial historical bias as ART techniques have improved., Study Design, Size, Duration: This was a population-based cohort study linking ART cycles reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) from 1 January 2004 to 31 December 2015 that resulted in live births from 1 September 2004 to 31 December 2016 in Massachusetts and North Carolina and from 1 September 2004 to 31 December 2015 for Texas and New York: these were large and ethnically diverse States, with birth defect registries utilizing the same case definitions and data collected, and with high numbers of ART births annually. A 10:1 sample of non-ART births were chosen within the same time period as the ART birth. Naturally conceived ART siblings were identified through the mother's information. Non-ART children were classified as being born to women who conceived with ovulation induction (OI)/IUI when there was an indication of infertility treatment on the birth certificate, but the woman did not link to the SART CORS; all others were classified as being naturally conceived., Participants/materials, Setting, Methods: The study population included 135 051 ART children (78 362 singletons and 56 689 twins), 23 647 naturally conceived ART siblings (22 301 singletons and 1346 twins) and 9396 children born to women treated with OI/IUI (6597 singletons and 2799 twins) and 1 067 922 naturally conceived children (1 037 757 singletons and 30 165 twins). All study children were linked to their respective State birth defect registries to identify major defects diagnosed within the first year of life. We classified children with major defects as either chromosomal (i.e. presence of a chromosomal defect with or without any other major defect) or nonchromosomal (i.e. presence of a major defect but having no chromosomal defect), or all major defects (chromosomal and nonchromosomal). Logistic regression models were used to generate adjusted odds ratios (AORs) and 95% CI to evaluate the risk of birth defects due to conception with ART (using autologous oocytes and fresh embryos), and with and without the use of ICSI in the absence or presence of male factor infertility, with naturally conceived children as the reference. Analyses within the ART group were stratified by combinations of oocyte source (autologous, donor) and embryo state (fresh, thawed), with births from autologous oocytes and fresh embryos as the reference. Analyses limited to fresh embryos were stratified by oocyte source (autologous, donor) and the use of ICSI. Triplets and higher-order multiples were excluded., Main Results and the Role of Chance: A total of 21 998 singleton children (1.9%) and 3037 twin children (3.3%) had a major birth defect. Compared to naturally conceived children, ART singletons (conceived from autologous oocytes, fresh embryos without the use of ICSI) had increased risks of a major nonchromosomal birth defect (AOR 1.18, 95% 1.05, 1.32), cardiovascular defects (AOR 1.20, 95% CI 1.03, 1.40), and any birth defect (AOR 1.18, 95% CI 1.09, 1.27). Compared to naturally conceived children, ART singletons conceived (from autologous oocytes, fresh embryos) with the use of ICSI, the risks were increased for a major nonchromosomal birth defect (AOR 1.30, 95% CI 1.16, 1.45 without male factor diagnosis; AOR 1.42, 95% CI 1.28, 1.57 with male factor diagnosis); blastogenesis defects (AOR 1.49, 95% CI 1.08, 2.05 without male factor; AOR 1.56, 95% CI 1.17, 2.08 with male factor); cardiovascular defects (AOR 1.28, 95% CI 1.10,1.48 without male factor; AOR 1.45, 95% CI 1.27, 1.66 with male factor); in addition, the risk for musculoskeletal defects was increased (AOR 1.34, 95% CI 1.01, 1.78 without male factor) and the risk for genitourinary defects in male infants was increased (AOR 1.33, 95% CI 1.08, 1.65 with male factor). Comparisons within ART singleton births conceived from autologous oocytes and fresh embryos indicated that the use of ICSI was associated with increased risks of a major nonchromosomal birth defect (AOR 1.18, 95% CI 1.03, 1.35), blastogenesis defects (AOR 1.65, 95% CI 1.08, 2.51), gastrointestinal defects (AOR 2.21, 95% CI 1.28, 3.82) and any defect (AOR 1.11, 95% CI 1.01, 1.22). Compared to naturally conceived children, ART singleton siblings had increased risks of musculoskeletal defects (AOR 1.32, 95% CI 1.04, 1.67) and any defect (AOR 1.15, 95% CI 1.08, 1.23). ART twins (conceived with autologous oocytes, fresh embryos, without ICSI) were at increased risk of chromosomal defects (AOR 1.89, 95% CI 1.10, 3.24) and ART twin siblings were at increased risk of any defect (AOR 1.26, 95% CI 1.01, 1.57). The 18% increased risk of a major nonchromosomal birth defect in singleton infants conceived with ART without ICSI (∼36% of ART births), the 30% increased risk with ICSI without male factor (∼33% of ART births), and the 42% increased risk with ICSI and male factor (∼31% of ART births) translates into an estimated excess of 386 major birth defects among the 68 908 singleton children born by ART in 2017., Limitations, Reasons for Caution: In the SART CORS database, it was not possible to differentiate method of embryo freezing (slow freezing vs vitrification), and data on ICSI was only available in the fresh embryo ART group. In the OI/IUI group, it was not possible to differentiate type of non-ART treatment utilized, and in both the ART and OI/IUI groups, data were unavailable on duration of infertility., Wider Implications of the Findings: The use of ART is associated with increased risks of a major nonchromosomal birth defect, cardiovascular defect and any defect in singleton children, and chromosomal defects in twins; the use of ICSI further increases this risk, the most with male factor infertility. These findings support the judicious use of ICSI only when medically indicated. The relative contribution of ART treatment parameters versus the biology of the subfertile couple to this increased risk remains unclear and warrants further study., Study Funding/competing Interest(s): This project was supported by grant R01 HD084377 from the National Institute of Child Health and Human Development.

Objective: To describe the current practice indications, methodology, and outcomes from a real-world experience of intravaginal culture (IVC) using INVOCELL., Design: A descriptive study outlining real-world experience with INVOCELL that addresses patient selection, ovarian stimulation, embryology laboratory practices, and outcomes., Setting: Five fertility centers in Missouri, Texas, North Carolina, South Carolina, and Virginia., Patients: Four hundred sixty-three patients undergoing 526 cycles., Intervention: IVC using INVOCELL., Main Outcome Measures: Cumulative pregnancy rate and live births. Secondary outcomes of interest included percent good quality embryos., Results: IVC with INVOCELL was primarily used in women <38 years with anti-Mullerian hormone level >0.8 ng/mL. The mean numbers of retrieved oocytes ranged from 9.2 to 16. Mean numbers of oocytes and sperm-injected oocytes loaded per INVOCELL ranged from a mean of 6.4-9.5 with a reported maximum of 34 oocytes loaded into the device. Most (95%) of the embryos were transferred on day 5. The mean blastocyst recovery per oocyte loaded into the device ranged from 19% to 34%; mean cumulative live birth plus ongoing pregnancy rates ranged from 29% to 53% per cycle start and 40% to 61% per transfer., Conclusions: This study of IVC using INVOCELL as an alternative model for infertility treatment confirms its utility as a viable alternative to standard incubator-based in vitro fertilization. The technology is compatible within the current framework of practice patterns and, when appropriately used, results in acceptable blastocyst recovery and live birth rates. Further use of INVOCELL in other clinical situations is warranted., (© 2020 The Authors.)

Importance: Children with birth defects have a greater risk of developing cancer, but this association has not yet been evaluated in children conceived with in vitro fertilization (IVF)., Objective: To assess whether the association between birth defects and cancer is greater in children conceived via IVF compared with children conceived naturally., Design, Setting, and Participants: This cohort study of live births, birth defects, and cancer from Massachusetts, New York, North Carolina, and Texas included 1 000 639 children born to fertile women and 52 776 children conceived via IVF (using autologous oocytes and fresh embryos) during 2004-2016 in Massachusetts and North Carolina, 2004-2015 in New York, and 2004-2013 in Texas. Children were followed up for an average of 5.7 years (6 008 985 total person-years of exposure). Data analysis was conducted from April 1 to August 31, 2020., Exposures: Conception by IVF for state residents who gave birth to liveborn singletons during the study period. Birth defect diagnoses recorded by statewide registries., Main Outcomes and Measures: Cancer diagnosis as recorded by state cancer registries. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% CIs for birth defect-cancer associations separately in fertile and IVF groups., Results: A total of 1 000 639 children (51.3% boys; 69.7% White; and 38.3% born between 2009-2012) were in the fertile group and 52 776 were in the IVF group (51.3% boys; 81.3% White; and 39.6% born between 2009-2012). Compared with children without birth defects, cancer risks were higher among children with a major birth defect in the fertile group (hazard ratio [HR], 3.15; 95% CI, 2.40-4.14) and IVF group (HR, 6.90; 95% CI, 3.73-12.74). The HR of cancer among children with a major nonchromosomal defect was 2.07 (95% CI, 1.47-2.91) among children in the fertile group and 4.04 (95% CI, 1.86-8.77) among children in the IVF group. The HR of cancer among children with a chromosomal defect was 15.45 (95% CI, 10.00-23.86) in the fertile group and 38.91 (95% CI, 15.56-97.33) in the IVF group., Conclusions and Relevance: This study found that among children with birth defects, those conceived via IVF were at greater risk of developing cancer compared with children conceived naturally.

Objective: To evaluate the efficacy and safety of highly purified human menotropin (HP-hMG) and recombinant follicle-stimulating hormone (rFSH) for controlled ovarian stimulation in a population of patients predicted to be high responders., Design: Randomized, open-label, assessor-blinded, parallel-group, noninferiority trial., Setting: Fertility centers., Patient(s): A total of 620 women with serum antimüllerian hormone (AMH) ≥5 ng/mL., Intervention(s): Controlled ovarian stimulation with HP-hMG or rFSH in a GnRH antagonist assisted reproductive technology (ART) cycle. Fresh transfer of a single blastocyst was performed unless ovarian response was excessive, in which all embryos were cryopreserved. Subjects could undergo subsequent frozen blastocyst transfer within 6 months of randomization., Main Outcome Measure(s): Ongoing pregnancy rate (OPR) after fresh transfer (primary endpoint), as well as cumulative live birth, ovarian hyperstimulation syndrome (OHSS), and pregnancy loss rates., Results: OPR/cycle start after fresh transfer was 35.5% with HP-hMG and 30.7% with rFSH (difference: 4.7%, 95% CI -2.7%, 12.1%); noninferiority was established. Compared to rFSH, HP-hMG was associated with significantly lower OHSS (21.4% vs. 9.7% respectively; difference: -11.7%, 95% CI -17.3%, -6.1%) and cumulative early pregnancy loss rates (25.5% vs. 14.5% respectively; difference: -11.0%, 95% CI -18.8%, -3.14%). Despite 43 more transfers in the rFSH group, cumulative live birth rates were similar with HP-hMG and rFSH at 50.6% and 51.5% respectively (difference: -0.8%, 95% CI -8.7%, 7.1%)., Conclusion(s): In high responders, HP-hMG provided comparable efficacy to rFSH with fewer adverse events, including pregnancy loss, suggesting its optimized risk/benefit profile in this population., Clinical Trial Registration Number: NCT02554279 (clinicaltrials.gov)., (Copyright © 2020 The Authors.

Objective: To evaluate if there are differences in standardized testing results at the end of third grade between children conceived with the use of in vitro fertilization (IVF) and those conceived spontaneously., Design: Retrospective population-based cohort., Setting: Texas public school system., Patient(s): Singleton and twin children 8-9 years of age who took the third-grade public school standardized testing in Texas from 2012 to 2018., Intervention(s): None., Main Outcome Measure(s): Standardized testing in reading and mathematics., Result(s): After exclusions, there were 6,970 IVF and 12,690 non-IVF children with reading scores and 6,973 IVF and 12,729 non-IVF children with mathematics scores. IVF children scored significantly higher in reading (singletons: 1,543 ± 2 vs. 1,525 ± 1; twins: 1,534 ± 2 vs. 1,504 ± 5 [mean ± SE]), and mathematics (singletons: 1,566 ± 2 vs. 1,550 ± 1; twins: 1,557 ± 2 vs. 1,529 ± 5). Children of mothers ≥30 years of age scored consistently higher than children of mothers 18-29 years of age. The differences were of similar magnitude between IVF and control children for older ages, but not significant for IVF. Within the IVF group, there were no significant differences between children born from fresh versus froze-thawed embryos., Conclusion(s): Children of ages 8-9 years who were conceived with the use of IVF performed as well on third-grade reading and math assessments as their counterparts who were conceived spontaneously. We also found consistent racial and ethnic differences, gender differences, and beneficial effects of older maternal age. Because we were not able to adjust adequately for socioeconomic status and other confounding factors, which may explain some of the observed differences, we conclude that there is no negative effect of IVF conception on academic achievement in third grade., (Copyright © 2020 American Society for Reproductive Medicine.

Research Question: What concentration of anti-Müllerian hormone (AMH) corresponds to an antral follicle count (AFC) >15 for determination of ovarian reserve?, Design: A prospective study conducted at 13 US fertility clinics in women aged 21-44 years who presented for AFC evaluation by transvaginal ultrasound. Serum samples were collected at the time of AFC evaluation (menstrual cycle day 2-4). AMH concentrations were measured by the Elecsys ® AMH immunoassay; oestradiol and follicle-stimulating hormone (FSH) concentrations were also measured. The serum AMH cut-off able to detect AFC >15 with high sensitivity was determined (derivation cohort). Clinical performance of the AMH assay at the derived cut-off was evaluated (validation cohort). Receiver operating characteristic (ROC) analyses were also performed., Results: In the derivation cohort (n = 306), an optimal serum AMH cut-off value of 1.77 ng/ml was determined to correspond to AFC >15 with 89.63% sensitivity and 69.01% specificity, using the Elecsys AMH assay. In the validation cohort (n = 856), this 1.77 ng/ml cut-off could identify women with an AFC >15 with a sensitivity of 88.34% and a specificity of 68.29%; corresponding positive predictive and negative predictive values were 75.19% and 84.34%, respectively. ROC analyses demonstrated that AMH performed better than oestradiol or FSH in predicting AFC, with area under the curves of 85.7%, 57.1% and 69.7%, respectively, in the validation cohort., Conclusion: The Elecsys AMH immunoassay provides a robust and fully automated method to measure serum AMH levels. Women with AMH values below the cut-off of 1.77 ng/ml are unlikely to have AFC >15., (Copyright © 2019 Roche Diagnostics Ltd. Published by Elsevier Ltd.. All rights reserved.)

Background: Over the past 2 decades the characteristics of women giving birth in the United States and the nature of the births themselves have changed dramatically, with increases in older maternal age, plural births, cesarean deliveries, and conception from infertility treatment., Objective: We sought to evaluate the risk of severe maternal morbidity by maternal fertility status, and for in vitro fertilization pregnancies, by oocyte source and embryo state combinations., Study Design: Women in 8 states who underwent in vitro fertilization cycles resulting in a live birth during 2004 through 2013 were linked to their infant's birth certificates; a 10:1 sample of births from non-in vitro fertilization deliveries were selected for comparison; those with an indication of infertility treatment on the birth certificate were categorized as subfertile, all others were categorized as fertile. In vitro fertilization pregnancies were additionally categorized by oocyte source (autologous vs donor) and embryo state (fresh vs thawed). Maternal morbidity was identified from the birth certificate, modeled using logistic regression, and reported as adjusted odds ratios [95% confidence intervals]. The reference group was fertile women., Results: The study population included 1,477,522 pregnancies (1,346,118 fertile, 11,298 subfertile, 80,254 in vitro fertilization autologous-fresh, 21,964 in vitro fertilization autologous-thawed, 13,218 in vitro fertilization donor-fresh, and 4670 in vitro fertilization donor-thawed pregnancies): 1,420,529 singleton, 54,573 twin, and 2420 triplet+ pregnancies. Compared to fertile women, subfertile and the 4 groups of in vitro fertilization-treated women had increased risks for blood transfusion and third- or fourth-degree perineal laceration (subfertile, 1.58 [1.23-2.02] and 2.08 [1.79-2.43]; autologous-fresh, 1.33 [1.14-1.54] and 1.37 [1.26-1.49]; autologous-thawed, 1.94 [1.60-2.36] and 2.10 [1.84-2.40]; donor-fresh, 2.16 [1.69-2.75] and 2.11 [1.66-2.69]; and donor-thawed, 2.01 [1.38-2.92] and 1.28 [0.79-2.08]). Also compared to fertile women, the risk of unplanned hysterectomy was increased for in vitro fertilization-treated women in the autologous-thawed group (2.80 [1.96-4.00]), donor-fresh group (2.14 [1.33-3.44]), and the donor-thawed group (2.46 [1.33-4.54]). The risk of ruptured uterus was increased for in vitro fertilization-treated women in the autologous-fresh group (1.62 [1.14-2.29]). Among women with a prior birth, the risk of blood transfusion after a vaginal birth was increased for subfertile women (2.91 [1.38-6.15]), and women in all 4 in vitro fertilization groups (autologous-fresh, 1.93 [1.23-3.01]; autologous-thawed, 2.99 [1.78-5.02]; donor-fresh, 5.13 [2.39-11.02]; and donor-thawed, 5.20 [1.83-14.82]); the risk after a cesarean delivery was increased in the autologous-thawed group (1.74 [1.29-2.33]) and the donor-fresh group (1.62 [1.07-2.45]). Unplanned hysterectomy was increased in the autologous-thawed (2.31 [1.43-3.71]) and donor-thawed (2.45 [1.06-5.67]) groups., Conclusion: The risks of severe maternal morbidity are increased for subfertile and in vitro fertilization births, particularly in pregnancies that are not from autologous, fresh cycles., (Copyright © 2018.

Purpose: To evaluate the risk of prematurity and infant mortality by maternal fertility status, and for in vitro fertilization (IVF) pregnancies, by oocyte source and embryo state combinations., Methods: Women in 14 States who had IVF-conceived live births during 2004-13 were linked to their infant's birth and death certificates; a 10:1 sample of non-IVF births was selected for comparison; those with an indication of infertility treatment on the birth certificate were categorized as subfertile, all others were categorized as fertile. Risks were modeled separately for the fertile/subfertile/IVF (autologous-fresh only) group and for the IVF group by oocyte source-embryo state combinations, using logistic regression, and reported as adjusted odds ratios (AORs) and 95% confidence intervals (CI)., Results: The study population included 2,474,195 pregnancies. Placental complications (placenta previa, abruptio placenta, and other excessive bleeding) and prematurity were both increased with pregestational and gestational diabetes and hypertension, among subfertile and IVF groups, and in IVF pregnancies using donor oocytes. Both subfertile and IVF pregnancies were at risk for prematurity and NICU admission; IVF infants were also at risk for small-for-gestation birthweight, and subfertile infants had greater risks for neonatal and infant death. Within the IVF group, pregnancies with donor oocytes and/or thawed embryos were at greater risk of large-for-gestation birthweight, and pregnancies with thawed embryos were at greater risk of neonatal and infant death., Conclusions: Prematurity was associated with placental complications, diabetes and hypertension, subfertility and IVF groups, and in IVF pregnancies, donor oocytes and/or thawed embryos.

Objective: To assess the attitudes of Society for Assisted Reproductive Technology (SART) members regarding expanding insurance coverage for patients seeking assisted reproductive technologies (ART) and identify some of the factors that may influence such attitudes., Design: An anonymous online 14-question survey of SART membership; 1,556 surveys were sent through the SART Research Portal from June to December 2017. Questions were incremental in scope, beginning with expanding insurance coverage for ART for vulnerable populations (e.g., fertility preservation for cancer, couples with same recessive gene, fertility preservation for transgender individuals) to extending coverage to include patients who were uninsured for ART. Additional questions assessed attitudes about assuming some fiscal responsibility if mandated insurance were contingent on elective single-embryo transfer (eSET) and lower charges in anticipation of increased number of cases., Setting: Not applicable., Patient(s): Not applicable., Intervention(s): Not applicable., Main Outcome Measure(s): Specific response to 14 survey questions., Result(s): The overall response rate was 43.4% (675/1,556). A large majority (>95%) favored insurance for fertility preservation for cancer patients and for avoidance of genetic disorders; 62.3% were supportive of infertility insurance coverage for transgender patients; 78% supported expanding insurance for the broadest segment of the general uninsured population; 76.7% supported expanding insurance contingent on eSET; and 51.3% would consider expanding insurance contingent on lowering charge per cycle in general, but only 23% responded as to what lower charge would be acceptable. Three of four factors were shown by multivariable logistic regression to be predictive of attitudes willing to expand insurance: practice setting (academic > hybrid > private), practicing in a mandated state, and higher annual volume of cases (>500 cycles); these had significant increased adjusted odds ratios ranging from 1.7 to 2.9. A fourth factor, the professional role one had in the practice, was not found to be of significant predictive value., Conclusion(s): The great majority of respondents were supportive of expanding insurance for specific segments of vulnerable populations with special needs and for the population who are presently uninsured. Furthermore, the majority of respondents would consider expanding insurance coverage contingent on age-appropriate eSET but have concerns about reduced reimbursement. Those most likely to be willing to expand insurance are those who practice in an academic setting or a mandated state and/or have a high annual volume of cases., (Copyright © 2018 American Society for Reproductive Medicine.

Purpose: The purpose of this study is to to compare the efficacy of intravaginal culture (IVC) of embryos in INVOcell™ (INVO Bioscience, MA, USA) to traditional in vitro fertilization (IVF) incubators in a laboratory setting using a mild pre-determined stimulation regimen based solely on anti-mullerian hormone (AMH) and body weight with minimal ultrasound monitoring. The primary endpoint examined was total quality blastocysts expressed as a percentage of total oocytes placed in incubation. Secondary endpoints included percentage of quality blastocysts transferred, pregnancy, and live birth rates., Methods: In this prospective randomized open-label controlled single-center study, 40 women aged <38 years of age with a body mass index (BMI) of <36 and an AMH of 1-3 ng/mL were randomized prior to trigger to receive either IVC or IVF. Controlled ovarian stimulation was administered with human menopausal gonadotropin (hMG) in a fixed gonadotropin-releasing hormone (GnRH) agonist cycle based solely on AMH and body weight. A single ultrasound-monitoring visit was performed on the 10th day of stimulation. One or two embryos were transferred following 5 days of culture., Results: IVF produced a greater percentage of total quality embryos as compared to IVC (50.6 vs. 30.7 %, p = 0.0007, respectively). There was no significant difference between in IVF and IVC in the percentage of quality blastocysts transferred (97.5 vs. 84.9 %, p = 0.09) or live birth rate (60 % IVF, 55 % IVC)., Conclusions: IVF was shown to be superior to IVC in creating quality blastocysts. However, both IVF and IVC produced identical blastocysts for transfer resulting in similar live birth rates. IVC using INVOcell™ is effective and may broaden access to fertility care in selected patient populations by ameliorating the need for a traditional IVF laboratory setting. Further studies will help elucidate the potential physiological, psychological, geographic, and financial impact of IVC on the delivery of fertility care.

The clinic-specific public reporting of assisted reproductive technology (ART) outcomes has been mandated by Federal law since 1992. As of late, a series of scientific and medical advances have all but deconstructed ART practice patterns thereby demanding that current reporting platforms be reevaluated for their continued ability to afford the public with credible and understandable estimates of conception per initiated cycle. In this Clinical Opinion, we trace the history of the public reporting of ART, describe the recently modified (present day) reporting platform, and explore potential future improvements thereof., (Copyright © 2015 Elsevier Inc.

Background: Administration of exogenous progesterone for luteal phase support has become a standard of practice. Intramuscular (IM) injections of progesterone in oil (PIO) and vaginal administration of progesterone are the primary routes of administration. This report describes the administration preferences expressed by women with infertility that were given progesterone vaginal insert (PVI) or progesterone in oil injections (PIO) for luteal phase support during fresh IVF cycles., Methods: A questionnaire to assess the tolerability, convenience, and ease of administration of PVI and PIO given for luteal phase support was completed by infertile women diagnosed with PCOS and planning to undergo IVF. The women participated in an open-label study of highly purified human menopausal gonadotropins (HP-hMG) compared with recombinant FSH (rFSH) given for stimulation of ovulation., Results: Most women commented on the convenience and ease of administration of PVI, while a majority of women who administered IM PIO described experiencing pain. In addition, their partners often indicated that they had experienced at least some anxiety regarding the administration of PIO. The most distinguishing difference between PVI and PIO in this study was the overall patient preference for PVI. Despite the need to administer PVI either twice a day or three times a day, 82.6% of the patients in the PVI group found it "very" or "somewhat convenient" compared with 44.9% of women in the PIO group., Conclusions: The results of this comprehensive, prospective patient survey, along with findings from other similar reports, suggest that PVI provides an easy-to-use and convenient method for providing the necessary luteal phase support for IVF cycles without the pain and inconvenience of daily IM PIO. Moreover, ongoing pregnancy rates with the well-tolerated PVI were as good as the pregnancy rates with PIO., Trial Registration: ClinicalTrial.gov, NCT00805935.

Purpose: To determine whether postwashed total progressively motile sperm count (TPMSC) obtained by CASA estimates could predict positive pregnancy test result in non-donor IUI cycles., Methods: Six thousand eight hundred and seventy one (6,871) IUI cycles with non-donor semen were retrospectively analyzed. Patient, cycle characteristics and prewashed and postwashed semen parameters were included in analysis. The main outcome measure was the positive pregnancy test result., Results: The pregnancy rate per cycle (PR/cycle) when postwashed TPMSC is between 0-0.5 million, 0.51-1 million, 1.01-5 million, 5.01-10 million and greater than 10 million were 8.1% (42/520), 14.4 % (41/285), 16.1% (237/1,469), 18.4% (193/1,046) and 18.8% (668/3,551) respectively. The predicted odd of positive pregnancy result is statistically significantly higher when TPMSC is >0.51 million compared to the TPMSC of <0.51 million (OR = 1.68, 95% CI: 1.04-2.71). The predicted odd of positive pregnancy result is greatest when TPMSC is at least 5 million (OR = 2, 95% CI: 1.38 to 2.9)., Conclusion: TPMSC is an independent predictor of pregnancy test result and TPMSC of half million or greater is adequate to achieve statistically similar pregnancy test results after non-donor IUI cycles.

Clinics performing assisted reproductive technology (ART) procedures have collected data via registry and publicly reported pregnancy outcomes for more than 25 years. During this time, the practice of ART has changed considerably with frozen embryo transfer (FET) procedures contributing an increasing proportion of live births. Cycles initiated with the intent of embryo banking for the purpose of fertility preservation have been excluded from these public reports, because pregnancy outcomes are not immediately available. An unintended consequence of the common sense handling of fertility preservation has been that cycles performed with intentional short-term cryopreservation of all embryos for other indications have also been excluded from the report. Over the last few years, cryopreservation with short-term delayed transfer increasingly has been performed for reasons other than fertility preservation. The pregnancy outcomes of these cycles are expected within a reasonable time frame and should be transparently reported. The Society for Assisted Reproductive Technology has collaborated with the Centers for Disease Control and Prevention to "recapture" these cycles for the public reports. This recapture is done by linking the FET cycles to the stimulation cycles from which the embryos were derived and by changing the labels of the outcome success metrics. Stimulations using ART, initiated for the purpose of transferring embryos within 1 year will be included in the report despite any prospective intent to freeze all eggs or embryos. A positive outcome will be reported when a live birth results from the first embryo transfer following stimulation ("primary transfer"). Linkage of ovarian stimulation and egg-retrieval procedures to FET will also allow development of other success metrics to further benefit fertility patients., (Copyright © 2014 American Society for Reproductive Medicine.

Background: Our study compares the efficacy of the combined contraceptive vaginal ring to oral contraceptive pills (OCPs) for hypothalamic-pituitary-ovarian (HPO) axis suppression in egg donor in vitro fertilization (IVF) cycles., Methods: Our retrospective cohort study includes patients from the Center for Assisted Reproduction (CARE) in Bedford, Texas undergoing IVF cycles as egg donors from January 2003 through December 2009. Twenty-five and thirty-nine women were treated with OCPs and the combined contraceptive vaginal ring, respectively. Statistical analyses were performed using the SigmaStat Software package (Systat, Chicago, IL). Data were analyzed by t or Mann-whitney test and Chi-square of Fisher exact test. Statistical significance was set at p<0.05., Results: Prior to gonadotropin initiation, endometrial thickness and serum estradiol were 5.6±2.6 mm and 33.6±19.9 pg/ml in the OCP group and 6.0±2.4 mm and 36.6±24.3 pg/ml in the combined contraceptive vaginal ring group, respectively (p=0.49 and p=0.33). Average serum FSH and LH were 1.7±1.9 and 1.7±2.5 mIU/ml in the OCP group and 1.7±1.6 and 1.2±1.4 mIU/ml in the combined contraceptive vaginal ring group, respectively (p=0.45 and p=0.95). No significant differences were found for gonadotropin requirement, peak estradiol, maximal endometrial thickness, number of oocytes retrieved, number of normally fertilized embryos, number of cryopreserved embryos, or live birth rates., Conclusion: The combined contraceptive vaginal ring is effective for HPO axis suppression in egg donor IVF cycles and associated with cycle characteristics similar to those observed with OCP treatment. The combined contraceptive vaginal ring may provide an important advantage over OCPs due to improved patient compliance.

Objective: To explore the comparative efficacy, safety, and tolerability of agents used for ovarian stimulation and luteal support when applied in a population of women undergoing in vitro fertilization (IVF) using a gonadotropin-releasing hormone (GnRH) antagonist protocol., Study Design: A phase 4, multicenter, randomized, open-label, exploratory clinical trial was performed at 7 assisted reproductive technology centers in the United States. Subjects included 173 women aged 18-42 years with a documented history of infertility who were undergoing IVF. Subjects were randomized to treatment with highly purified human menopausal gonadotropin (HP-hMG) or recombinant human follicle-stimulating hormone (rhFSH) for ovarian stimulation and progesterone vaginal inserts (PVIs) or intramuscular injection of progesterone in oil (PIO) for luteal support. Protocols for IVF followed the standard practices of participating centers within the parameters of the study., Results: Biochemical, clinical, and ongoing pregnancy rates were the main outcome measures. Ongoing pregnancy rates for individual treatment groups ranged from 44.0-46.9%. No statistically significant differences were observed in pregnancy outcomes for the comparisons of HP-hMG vs. rhFSH or PVI vs. PIO. All study medications were generally safe and well tolerated., Conclusion: In this study HP-hMG and rhFSH were equally effective for ovarian stimulation during GnRH antagonist IVF cycles. Both PVI and PIO are viable options for luteal support.

Objective: To determine the sensitivity and specificity of hyperglycosylated hCG (hhCG) measurements for the diagnosis of clinical pregnancies in the IVF setting and how soon post embryo transfer (ET) a pregnancy can be detected using an ultrasensitive (hhCG) assay. To determine if a single, early hhCG measurement can discriminate between biochemical and clinical pregnancies., Design: A 4 center prospective blinded clinical trial was performed with patients undergoing IVF-ET. Patients had blood drawn and submitted for hhCG analysis on the day of ET and at days 4, 6, 8, and 12 thereafter. First morning urines were collected and submitted for hhCG analysis on days 0, 4, 6, 8, 10 and 12., Setting: Fertility Centers, Outcome Measures: Clinical pregnancies were defined as an ultrasound study demonstrating a gestational sac and/or heart beat at appropriate gestational ages., Results: Fifty-six of 58 enrolled patients completed the study. There were 25 clinical and 6 biochemical pregnancies. For blastocyst transfers, a single serum or urine hhCG measurement identified pregnancies (both biochemical and clinical) at 6 days post ET with 100% sensitivity and specificity. There were 6 biochemical pregnancies, all following blastocyst transfers. All of these pregnancies were identified by lower values.

The relationship between endogenous LH concentrations and ongoing pregnancy rates among normogonadotrophic patients undergoing ovarian stimulation in a gonadotrophin-releasing hormone antagonist protocol were examined. In the Engage trial, 1506 patients received corifollitropin alfa (150 μg) or daily recombinant FSH (rFSH) (200 IU) for the first 7 days of stimulation with 0.25mg ganirelix from stimulation day 5. Patients were retrospectively stratified by serum LH percentiles (< 25th, 25th-75th and >75th) on stimulation day 8 and day of human chorionic gonadotrophin administration. Odds ratios (OR) with and without adjustment for predictive factors for ongoing pregnancy were estimated. LH concentration was not associated with pregnancy rates in either treatment arm, in contrast to ovarian response and serum progesterone. With adjustment for these predictors and age, OR (95% confidence interval) for ongoing pregnancy on stimulation day 8 for LH categories < P25 versus ≥ P25, >P75 versus ≤ P75 and < P25 versus >P75 were 0.75 (0.53-1.06), 1.26 (0.87-1.83) and 0.70 (0.46-1.09) in the corifollitropin alfa arm and 0.80 (0.54-1.17), 1.28 (0.87-1.87) and 0.73 (0.46-1.16) in the rFSH arm respectively. There was also no significant difference in pregnancy rates between LH categories on day of human chorionic gonadotrophin administration with either treatment., (Copyright © 2011 Reproductive Healthcare Ltd.

Objective: To evaluate the efficacy and safety of minilaparotomy myomectomy in an ambulatory setting., Design: Retrospective, nonrandomized study., Setting: Center for Assisted Reproduction, Bedford, Texas., Patient(s): One hundred eighty-nine women desiring fertility with symptomatic uterine leiomyomata., Intervention(s): Minilaparotomy myomectomy in an ambulatory setting., Main Outcome Measure(s): Operative time, blood loss, recovery time, postoperative analgesia, and complications., Result(s): The mean diameter of the largest leiomyoma was 4.4 cm (range, 1-14 cm). The mean number and weight of the leiomyomata was 4.9 (range, 1-35) and 109.8 gm (range, 1-1,165 g), respectively. The mean operative time was 73 minutes, and the mean blood loss was 96 mL. On average, patients required 3.5 hours of recovery time. In the recovery room, patients received a mean of 12 mg of morphine/37 mg of meperidine for pain control postoperatively before discharge home. Only one major complication, pulmonary edema related to extubation, occurred., Conclusion(s): This study demonstrates that minilaparotomy myomectomy, when performed using a systematic operative technique, can be accomplished in an outpatient setting with minimal blood loss, fast recovery time, and a low complication rate. Postoperatively, patients require minimal analgesia, which permits them to be discharged home the same day. Minilaparotomy myomectomy is a safe, cost-effective treatment of most symptomatic uterine leiomyomata in an ambulatory setting., (Copyright © 2010 American Society for Reproductive Medicine.

Objective: To determine if the anti-Müllerian hormone (AMH), a proposed marker of ovarian aging, decreases with repetitive oocyte donation., Design: Retrospective cohort., Setting: Academic., Patient(s): Thirty-six young women who underwent three to seven oocyte donation cycles., Intervention(s): Assessor blind determination of AMH levels from serum samples collected during each treatment cycle., Main Outcome Measure(s): Cycle trends of serum AMH levels., Result(s): The AMH was the only predictor of oocyte yield in the first cycles. The AMH was negatively associated with donor age and follicle stimulating hormone (FSH) dose used. Serum AMH levels did not show any decrease per treatment cycle basis and per maximum number of oocyte donation cycles performed per woman. Whereas donors who underwent six cycles showed increasing AMH levels when controlled for studied covariates, the slopes of the multiple regression curves were not significantly different from donors who underwent three, four, and five cycles. Clinical outcome assessed by FSH dose/number of oocytes ratio did not show significant change over repetitive cycles. Intercycle variation of AMH in all patients over three cycles was found to be 12.5%, which was within the reported intermenstrual range., Conclusion(s): Serum AMH levels do not decrease over repetitive oocyte donation cycles, which may imply that accelerated ovarian aging may not occur in oocyte donors., (Copyright (c) 2010 American Society for Reproductive Medicine.

Objective: To assess the efficacy and safety of a vaginal progesterone (P(4)) insert (Endometrin) for luteal support for assisted reproductive technology (ART)., Design: Multicenter, randomized, open-label (assessor-blinded) phase III clinical trial., Setting: Twenty-five U.S. ART centers., Patient(s): A total of 1,211 ART patients randomized to three groups: Endometrin 100 mg twice daily (n = 404), Endometrin 100 mg three times daily (n = 404), and P(4) 90 mg 8% gel daily (n = 403)., Intervention(s): In vitro fertilization and ET were performed according to site-specific protocols. The day after oocyte retrieval, Endometrin or vaginal P(4) gel was begun for luteal support and continued for up to 10 weeks of pregnancy., Main Outcome Measure(s): Biochemical, clinical, and ongoing pregnancy and live birth rates., Result(s): Pregnancy rates were high and similar in all treatment groups, with biochemical rates exceeding 50%, clinical and ongoing rates >or=40%, and live birth rates at 35%-38%. The adverse event profiles were similar across groups., Conclusion(s): Pregnancy rates and live birth rates for Endometrin (twice daily and three times daily) were high and similar to those for P(4) gel. The adverse event profiles for both were similar to that for P(4) gel and primarily due to IVF stimulation and oocyte retrieval. Endometrin was safe and well tolerated.

Objective: To analyze the potential association between serum cetrorelix levels and clinical pregnancy outcome in patients who had undergone assisted reproduction cycles with a GnRH antagonist cetrorelix acetate 3-mg injection., Design: Retrospective case-control study., Setting: University-affiliated private-assisted reproduction center., Patient(s): 130 IVF and intracytoplasmic sperm injection first cycles, treated with the same cetrorelix acetate protocol, in two matched groups according to whether the cycle resulted in clinical pregnancy (n = 56) or not (n = 74)., Intervention(s): Cetrorelix acetate administration at 3 mg in a sandwich protocol., Main Outcome Measure(s): Serum cetrorelix concentrations on the day of hCG administration with regard to clinical pregnancy outcome, pre- versus post-hCG percent change in serum E(2) levels and implantation rates., Result(s): The cetrorelix serum concentrations were in the range of 0.29 to 5.12 ng/mL. The comparisons between groups with and without clinical pregnancy revealed comparable serum cetrorelix levels. There was no significant correlation between the serum cetrorelix concentrations and percent change in pre- versus post-hCG serum E(2) levels. Serum cetrorelix levels were comparable among patients with various implantation rates., Conclusion(s): Although a wide range of serum cetrorelix levels could be detected during a GnRH antagonist cycle, these levels were comparable in patients with and without clinical pregnancies.

Objective: To define and validate metrics of embryo progression and morphology during extended embryo culture and to compare the effects of early cleavage (EC) vs. blastulation stages on clinical pregnancy., Design: Retrospective observational study., Setting: University-affiliated assisted reproduction center., Patient(s): One thousand two hundred ninety-two intracytoplasmic sperm injection and 842 IVF blastocyst-transfer cycles., Intervention(s): The embryo progression index (EPI) was calculated as the area under the curve of total cell number (TCN) over time, by using observed TCN for cleavage-stage embryos and estimated blastocyst TCN according to morphology. The EPI from days 1-3 measured early cleavage, and blastulation was assessed by EPI over extended embryo culture. Blastocyst morphology was converted into numerical blastocyst quality scores (BQSs). Receiver operating characteristic curve analysis was used to evaluate predictors for clinical pregnancy., Main Outcome Measure(s): Clinical pregnancy., Result(s): Per-cycle mean EPI and mean BQS for all embryos developing into blastocysts, as well as mean BQS of the transferred embryos, were significant predictors of clinical pregnancy in intracytoplasmic sperm injection and IVF cycles. Mean EPI for days 1-3 did not predict outcome., Conclusion(s): Early cleavage is a putative marker of embryo quality. Late-stage embryo development is more sensitive and specific in predicting clinical pregnancy than is early cleavage, supporting the use of extended embryo culture for embryo selection. The embryo progression index and BQS may also be used for this purpose.

The outcome of a novel protocol utilizing precycle gonadotrophin-releasing hormone (GnRH) antagonist administration and LH activity support with microdose recombinant human chorionic gonadotrophin (HCG) was compared to GnRH agonist long protocol used in patients undergoing their first ICSI (n=707) or IVF (n=571) cycles, which had resulted in one or two blastocyst transfers. In GnRH antagonist cycles, cetrorelix acetate (3 mg) was administered s.c. 4 days before FSH stimulation and a repeat dose was given when the lead follicular diameter was 13-14 mm. LH support was provided by recombinant HCG (2.5 microg). Embryo progression and blastulation were evaluated using embryo progression indices and blastocyst quality scores. The tested protocol demonstrated reduced implantation and clinical pregnancy rates as compared with GnRH agonist long protocol, although the embryo progression and blastulation parameters and blastocyst quality were comparable among the groups. Logistic regression models further supported the significant negative impact of GnRH antagonist/microdose HCG protocol on clinical pregnancy rates in both ICSI and IVF patients. Assisted reproduction cycles with fresh blastocyst transfers utilizing precycle GnRH antagonist administration and microdose HCG support resulted in lower implantation and clinical pregnancy rates as compared with GnRH agonist cycles, although the embryo progression and blastulation parameters were comparable.

Uterine myomas are the most common solid pelvic tumors in women and the primary indication for hysterectomy. Most of the myomas are asymptomatic. The most common symptoms associated with uterine myomas are abnormal uterine bleeding and pelvic discomfort mostly caused by the mass effect. Vaginal bleeding may lead to iron deficiency anemia. Uterine myomas have a significant role in reproductive dysfunction, although a causal relationship between infertility and intramural or subserosal myomas not disturbing the uterine cavity has not been established clearly. Nevertheless myomas, especially the tumors distorting the uterine cavity, are associated with infertility and spontaneous miscarriage. In addition, the myomas may be the potential cause for numerous obstetric complications, especially if they are located adjacent to placenta. The transformation of myomas to leiomyosarcomas is a very rare event. Leiomyosarcomas may be suspected in postmenopausal women with rapidly growing symptomatic solid pelvic mass. Despite the high prevalence of these tumors, there is paucity of data available regarding the natural clinical history of myomas.

To review the use of hCG and to describe the clinical benefit of recombinant hCG (r-hCG) based on the published results of prospective, randomized studies. Review of published articles. Tertiary infertility care center.None.None. Oocyte number and quality, luteal phase progesterone, pregnancy and OHSS rate, and local tolerability. The published data consistently show that single doses of 250 microg r-hCG and 5,000 IU urinary (u)-hCG produce similar clinical outcomes when used in infertility treatment cycles for timed intercourse, IUI, and IVF in terms of the number of oocytes retrieved, number of mature oocytes harvested, and fertilization and pregnancy rates attained. Single doses of 10,000 IU u-hCG also gave results comparable to single doses of 250 microg r-hCG. P levels in the midluteal phase were significantly higher with the use of r-hCG compared with u-hCG, and local injection site adverse effects were significantly less frequent, demonstrating the higher purity of the recombinant product. A single 500-microg dose of r-hCG led to a higher rate of ovarian hyperstimulation syndrome compared with a 250-microg dose, with no significant improvement in pregnancy rates.A single dose of 250 microg r-hCG was at least as effective as single doses of 5,000 or 10,000 IU u-hCG but offered the advantages associated with use of a recombinant product: local injection site adverse effects were significantly less frequent with r-hCG than with u-hCG.

Purpose: Case studies of four in vitro fertilization (IVF) cycles where embryo transport by commercial airline followed by biopsy and genetic analysis with subsequent culture to Day 5 and resulting ongoing pregnancy., Method: Retrospective clinical case study of 4 patients requiring preimplantation genetic diagnosis (PGD) testing. Normally fertilized embryos were transported in a battery-powered portable incubator by commercial airline following evaluation for fertilization under controlled conditions from the Center for Assisted Reproduction, Bedford, Texas to the Reproductive Genetic Institute, Chicago, Illinois. Following Day 3 embryo biopsy and genetic analysis, embryos were transported back to the Center for Assisted Reproduction for Day 5 embryo transfer., Results: Ongoing clinical pregnancy resulted for all patients receiving embryo transfer., Conclusion: These results demonstrate the feasibility of embryo transport by air for centers that do not have the in-house capabilities to perform genetic analysis. With successful pregnancies obtained through extended culture to Day 5, embryos requiring genetic analysis can be successfully transported by air, tested, and returned to the initial facility for embryo transfer without time restriction.

In order to evaluate the niche of extended embryo culture in an IVF programme, retrospective analysis of non-selected IVF patients, who underwent ovarian stimulation from April 1998 to June 1999 in a single private practice assisted reproductive technology centre, was performed. Embryos were cultured for 48 h in S1/G1.2 medium followed by 48 to 72 h of culture in S2/G2.2 to day 5 or day 6. Only fertilized oocytes exhibiting two pronuclei from donor and non-donor IVF and intracytoplasmic sperm injection (ICSI) cases were examined to determine the relationship between embryo cell number on day 3 and subsequent rate of blastocyst formation. Results indicated that a proportional relationship existed between the number of blastomeres present in day 3 embryos and the rate of blastocyst formation. Fifty-four per cent of embryos that had six cells on day 3 formed blastocysts, while 76% of those embryos with eight cells formed blastocysts. Blastocyst development did not increase further when embryos had more than eight cells on day 3, indicating that embryos with greater cell numbers on day 3 are not always predictive of a greater likelihood of blastocyst formation. Fertilized oocytes exhibiting two pronuclei from donors produced significantly more blastocysts (67%) than those from IVF patients (52%; P < 0.01), and had a significantly higher implantation rate (54%) compared with IVF patients (30%; P < 0.01). Furthermore, blastocyst cryopreservation resulted in significantly higher implantation rates than cryopreserved cleavage stage embryos (P < 0.001).

Objective: To evaluate the nonselective application of extended embryo culture on the outcome of IVF., Design: Retrospective analysis., Setting: Private practice assisted reproductive technology center., Patient(s): Seven hundred ninety nonselected patients undergoing IVF with controlled ovarian stimulation., Intervention(s): For day 3 ET, multicell embryos were cultured in human tubal fluid medium and 12% synthetic serum substitute. For day 5 ET, embryos were cultured for 48 hours in S1 medium and then for 48 hours in S2 medium., Main Outcome Measure(s): Implantation rate (determined by total no. of visualized gestational sacs), ongoing pregnancy rate, and number of embryos available for ET., Result(s): Respective day 3 and day 5 implantation rates for patients aged <35 years (29.5% and 38.9%), patients aged 35-39 years (20.7% and 28.2%), and all patients combined (23.3% and 32.4%) were statistically significantly different. Significantly more embryos were transferred on day 3 than on day 5 for patients aged <35 years (2.9 vs. 2.4), patients aged 35-39 years (3.1 vs. 2.6), and all patients combined (3.0 vs. 2.5). The difference in ongoing pregnancy rates per retrieval was statistically significant for day 3 compared with day 5 transfers for all patients combined (35.9% vs. 43.8%). Cancellation rates for transfer after retrieval increased significantly for day 3 compared with day 5 transfer (2.9% vs 6.7%)., Conclusion(s): These results demonstrate the feasibility of using extended embryo culture in a nonselective manner for couples undergoing IVF. Overall, extended embryo culture was associated with a significant increase in pregnancy rates and implantation rates and a significant decrease in the number of embryos transferred. The rate of multiple implantation among patients aged <35 years warrants consideration of single blastocyst transfers for this group.

Male pseudohermaphrodites require gonadectomy for the prevention of gonadal malignancy. Laparoscopic gonadectomy has been performed in patients with intra-abdominal gonads and can also be performed in patients whose gonads are located within the inguinal canals.

In the present study, we examined the changes in enzyme activity and mRNA levels of aromatase cytochrome P450 (P450AROM) and 5 alpha-reductase in ovarian tissue from adult cyclic rats. For each stage of the estrous cycle, the enzymatic activities were quantified by means of the 3H2O-release assay in the case of P450AROM and thin-layer chromatography in the case of 5 alpha-reductase. Levels of mRNA encoding P450AROM and 5 alpha-reductase in the ovary were determined by Northern blot analysis utilizing 32P-labeled rat cDNAs as probes. Serum LH levels were determined by RIA. Three P450AROM mRNA species were detected (at 1.7, 2.2 and 2.7 kb) in ovarian tissue from cyclic rats. All three P450AROM transcripts were expressed in a co-ordinated fashion throughout the cycle. The P450AROM levels were highest during diestrus and proestrus, decreased during estrus while at metestrus the levels were nearly nondetectable. Conversely, one 5 alpha-reductase mRNA species at 2.5 kb was detected in ovarian tissue from cyclic animals. Ovarian 5 alpha-reductase mRNA levels were lowest during diestrus and proestrus, increased at estrus and were most abundant during metestrus; a pattern opposite to that of P450AROM. The pattern of change in P450AROM and 5 alpha-reductase activities paralleled that of the respective mRNA profiles but lagged behind the mRNA profiles by about 24 h, or one stage of the estrous cycle. Aromatase activity was 1.5 pmol/h/mg protein during diestrus, increased over 3-fold at proestrus (approximately 5.5 pmol/h/mg protein), decreased at estrus and declined to the lowest values at metestrus (approximately 1.0 pmol/h/mg protein). In contrast, the 5 alpha-reductase activity pattern was essentially the mirror image of the P450AROM activity pattern during the estrous cycle. 5 alpha-Reductase levels were lowest during proestrus (approximately 5 pmol/h/mg protein) and estrus (approximately 8 pmol/h/mg protein), increased over 3-fold during metestrus, while the highest activity levels occurred during diestrus (approximately 36 pmol/h/mg protein). The normalization of the P450AROM and 5 alpha-reductase mRNA levels and their respective enzyme activities revealed a correspondence between mRNA abundance and subsequent increases (24 h later) in enzyme activity levels during the estrous cycle. These findings suggest that: (a) a temporal relationship exists between the profiles of the enzymatic activities that follows the changes in the levels of their respective mRNAs and (b) an inverse pattern exists between P450AROM and 5 alpha-reductase in terms of both enzymatic activity and mRNA expression during the estrous cycle in rat.

We have examined the levels of expression of mRNA species encoding cholesterol side-chain cleavage cytochrome P-450 (P-450scc), 17 alpha-hydroxylase cytochrome P-450 (P-450(17 alpha), aromatase cytochrome P-450 (P-450AROM) and 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) in rat ovaries throughout the oestrous cycle, during pregnancy and in immature animals treated with pregnant mare serum gonadotrophin (PMSG). Total or poly(A)(+)-enriched RNA was prepared from adult rat ovaries throughout the oestrous cycle, from immature rat ovaries 24 and 48 h after treatment and from adult rat ovaries on days 10, 14, 17 and 21 of gestation. Expression of the mRNA species was examined by Northern analysis using specific [32P]cDNA probes. During the oestrous cycle P-450scc mRNA of approximately 1.9 kb was detected at low levels, while 3 beta-HSD mRNA of 1.7 kb was in relatively high abundance throughout the oestrous cycle. While P-450(17) alpha mRNA of 1.9 kb and P-450AROM of 2.7, 2.2 and 1.7 kb were highly abundant during dioestrus, pro-oestrus and oestrus, the levels of these mRNA species decreased markedly to be nearly undetectable during metoestrus. During pregnancy there was considerably more variation in the expression of the mRNA species examined. Expression of P-450scc mRNA was at low, but detectable, levels until day 14, thereafter expression increased to high levels (day 14-21 of gestation). Levels of P-450(17) alpha mRNA on day 10 of gestation were lower than at pro-oestrus during the oestrous cycle and decreased further on days 14 and 17. Expression of 3 beta-HSD was decreased on day 10, but on days 14, 17 and 21 of gestation high mRNA levels were detectable. Ovarian expression of the three P-450AROM species was dramatically increased between days 14 and 17 of pregnancy, but declined by day 21. In immature rats, P-450scc mRNA was detected at low levels in unstimulated animals and increased markedly after treatment with PMSG, while subsequent treatment with human chorionic gonadotrophin (hCG) had a minimal effect on expression. Expression of P-450(17) alpha mRNA was high in unstimulated immature and PMSG-treated rats, but diminished after treatment with hCG. All three P-450AROM mRNA species were undetectable in ovaries from unstimulated immature animals; however, induction of all three was observed in PMSG-treated rats, but this expression decreased to undetectable levels upon subsequent administration of hCG.(ABSTRACT TRUNCATED AT 400 WORDS)

The levels of expression of mRNA species encoding cholesterol side-chain cleavage cytochrome P-450 (P450scc), 17 alpha-hydroxylase cytochrome P450 (P450(17 alpha], aromatase cytochrome P-450 (P-450AROM), and 3 beta-hydroxysteroid dehydrogenase (3 beta HSD) were examined in human follicles and corpora lutea (CL) throughout the menstrual cycle. Tissues were obtained from women undergoing hysterectomy and oophorectomy. The largest follicle or the CL was dissected from the ovary depending on whether the surgery was performed in the follicular or luteal phase. The day of the cycle was determined by onset of last menstrual period and was confirmed by endometrial histology. Total RNA was examined by Northern blot analysis, using as probes specific 32P-labeled cDNA inserts encoding each human enzyme. Early follicles demonstrated detectable mRNA for both P450scc and P450(17 alpha), but not for P450AROM or 3 beta HSD. P450AROM was detectable late in the follicular phase and appeared markedly induced in the CL. 3 beta HSD was detectable only in the CL. Levels of P450(17 alpha) mRNA remained relatively unchanged throughout the cycle, whereas P450scc mRNA levels were greatly increased in the CL. The presence of P450(17 alpha) mRNA in the human CL is of interest, since it is absent from the bovine CL, and this is consistent with the ability of the human, but not the bovine, CL to synthesize 17 alpha-hydroxyprogesterone and estrogens. The fact that P450AROM expression is highest in CL is surprising, since plasma estrogen levels are highest during the late follicular phase of the cycle, and may suggest that CL estrogen biosynthesis is limited by 17 alpha-hydroxylase or 17,20-lyase activities.

The placenta has been shown to be the major source of estrogen production during pregnancy. This investigation was undertaken to compare the content and activity of aromatase in the placenta and various other human fetal tissues. Tissues were obtained from first- and second-trimester human abortuses. The amount of aromatase P-450 (aromatase cytochrome P-450) in tissue homogenates was determined after sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting by use of a polyclonal antibody directed against aromatase cytochrome P-450. The activity of aromatase in microsomal preparations was assayed by determining the rate of incorporation of tritium from 1-[3H]androstenedione into [3H]water. The greatest amount of aromatase cytochrome P-450 (55 kd) was detected in placenta and lesser amounts were detected in other tissues. Aromatase activity also was highest in placental microsome fractions (368 +/- 62.4 pmol/mg/hr [mean +/- SE], n = 9). A significant amount of aromatase activity was also detected in fetal liver (19 +/- 4.8 pmol/mg/hr, n = 7). Much less activity was found in brain (2.8 +/- 1.0 pmol/mg/hr, n = 6) and intestine (2.7 +/- 1.3 pmol/mg/hr, n = 7). Minimal activity was noted in adrenal (n = 5), spleen (n = 4), stomach (n = 4), and muscle (n = 5) (1.2 to 1.5 pmol/mg/hr). Activity in kidney (n = 7), heart (n = 4), and lung (n = 4) was extremely low (less than 0.8 pmol/mg/hr). In conclusion, the placenta is a major site of conversion of C19 steroid precursors to estrogens because of the amount of enzyme and the high rate of activity of aromatase compared with those of other fetal tissues. However, considering the size and rate of aromatase activity in other fetal tissues such as liver, brain, and intestine, these tissues also may contribute to the total estrogen production in the fetal-placental unit.
