Context Anti-Müllerian hormone (AMH) measured in adolescence as biomarker for prediction of adult polycystic ovary syndrome (PCOS) is doubtful but not substantiated. Objective To investigate whether serum AMH levels and other PCOS-associated features in adolescence can predict the presence of PCOS in adulthood. Design and Setting A long-term follow-up study based on a unique adolescent study on menstrual irregularities performed between 1990 and 1997. Participants and interventions AMH was assayed in 271 adolescent girls. Data on PCOS features were combined with AMH levels. In 160 of the 271 (59%) participants, we collected information in adulthood about their menstrual cycle pattern and presence of PCOS (features) by questionnaire 2 decades after the initial study. Results AMH was higher in adolescent girls with oligomenorrhea compared with girls with regular cycles, median (interquartile range): 4.6 (3.1-7.5) versus 2.6 (1.7-3.8) μg/L (P Conclusions Adolescent AMH either alone or adjuvant to adolescent oligomenorrhea does not contribute as prognostic marker for PCOS in adulthood. Therefore, we do not recommend routine its use in clinical practice.

STUDY QUESTION: Do cumulative live birth rates (CLBRs) over multiple IVF/ICSI cycles confirm the low prognosis in women stratified according to the POSEIDON criteria? SUMMARY ANSWER: The CLBR of low-prognosis women is ~56% over 18 months of IVF/ICSI treatment and varies between the POSEIDON groups, which is primarily attributable to the impact of female age. WHAT IS KNOWN ALREADY: The POSEIDON group recently proposed a new stratification for low-prognosis women in IVF/ICSI treatment, with the aim to define more homogenous populations for clinical trials and stimulate a patient-tailored therapeutic approach. These new criteria combine qualitative and quantitative parameters to create four groups of low-prognosis women with supposedly similar biologic characteristics. STUDY DESIGN, SIZE, DURATION: This study analyzed the data of a Dutch multicenter observational cohort study including 551 low-prognosis women, aged

STUDY QUESTION: Does a reduced FSH dose in women with a predicted hyper response, apparent from a high antral follicle count (AFC), who are scheduled for IVF/ICSI lead to a different outcome with respect to cumulative live birth rate and safety?SUMMARY ANSWER: Although in women with a predicted hyper response (AFC > 15) undergoing IVF/ICSI a reduced FSH dose (100 IU per day) results in similar cumulative live birth rates and a lower occurrence of any grade of ovarian hyperstimulation syndrome (OHSS) as compared to a standard dose (150 IU/day), a higher first cycle cancellation rate and similar severe OHSS rate were observed.WHAT IS KNOWN ALREADY: Excessive ovarian response to controlled ovarian stimulation (COS) for IVF/ICSI may result in increased rates of cycle cancellation, the occurrence of OHSS and suboptimal live birth rates. In women scheduled for IVF/ICSI, an ovarian reserve test (ORT) can be used to predict response to COS. No consensus has been reached on whether ORT-based FSH dosing improves effectiveness and safety in women with a predicted hyper response.STUDY DESIGN SIZE, DURATION: Between May 2011 and May 2014, we performed an open-label, multicentre RCT in women with regular menstrual cycles and an AFC > 15. Women with polycystic ovary syndrome (Rotterdam criteria) were excluded. The primary outcome was ongoing pregnancy achieved within 18 months after randomization and resulting in a live birth. Secondary outcomes included the occurrence of OHSS and cost-effectiveness. Since this RCT was embedded in a cohort study assessing over 1500 women, we expected to randomize 300 predicted hyper responders.PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with an AFC > 15 were randomized to an FSH dose of 100 IU or 150 IU/day. In both groups, dose adjustment was allowed in subsequent cycles (maximum 25 IU in the reduced and 50 IU in the standard group) based on pre-specified criteria. Both effectiveness and cost-effectiveness were evaluated from an intention-to-treat perspective.MAIN RESULTS AND THE ROLE OF CHANCE: We randomized 255 women to a daily FSH dose of 100 IU and 266 women to a daily FSH dose of 150 IU. The cumulative live birth rate was 66.3% (169/255) in the reduced versus 69.5% (185/266) in the standard group (relative risk (RR) 0.95 [95%CI, 0.85-1.07], P = 0.423). The occurrence of any grade of OHSS was lower after a lower FSH dose (5.2% versus 11.8%, RR 0.44 [95%CI, 0.28-0.71], P = 0.001), but the occurrence of severe OHSS did not differ (1.3% versus 1.1%, RR 1.25 [95%CI, 0.38-4.07], P = 0.728). As dose reduction was not less expensive (€4.622 versus €4.714, delta costs/woman €92 [95%CI, -479-325]), there was no dominant strategy in the economic analysis.LIMITATIONS, REASONS FOR CAUTION: Despite our training programme, the AFC might have suffered from inter-observer variation. Although strict cancellation criteria were provided, selective cancelling in the reduced dose group (for poor response in particular) cannot be excluded as observers were not blinded for the FSH dose and small dose adjustments were allowed in subsequent cycles. However, as first cycle live birth rates did not differ from the cumulative results, the open design probably did not mask a potential benefit for the reduced dosing group. As this RCT was embedded in a larger cohort study, the power in this study was unavoidably lower than it should be. Participants had a relatively low BMI from an international perspective, which may limit generalization of the findings.WIDER IMPLICATIONS OF THE FINDINGS: In women with a predicted hyper response scheduled for IVF/ICSI, a reduced FSH dose does not affect live birth rates. A lower FSH dose did reduce the incidence of mild and moderate OHSS, but had no impact on severe OHSS. Future research into ORT-based dosing in women with a predicted hyper response should compare various safety management strategies and should be powered on a clinically relevant safety outcome while assessing non-inferiority towards live birth rates.STUDY FUNDING/COMPETING INTEREST(S): This trial was funded by The Netherlands Organization for Health Research and Development (ZonMW, Project Number 171102020).

Objective: To assess the effectiveness of curettage versus expectant management in women with an incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.Study design: We conducted a multicenter cohort study alongside a randomized clinical trial (RCT) between June 2012 until July 2014. 27 Dutch hospitals participated. Women with an incomplete evacuation after misoprostol treatment for first trimester miscarriage who declined to participate in the RCT, received treatment of their preference; curettage (n = 65) or expectant management (n = 132). A successful outcome was defined as an empty uterus on sonography at six weeks or uneventful clinical follow-up. We furthermore assessed complication rate and (re)intervention rateResults: Of the 197 women who declined to participate in the RCT, 65 preferred curettage and 132 expectant management. A successful outcome was observed in 62/65 women (95%) in the surgical group versus 112/132 women (85%) in the expectant group (RR 1.1, 95% CI 1.03-1.2), with complication rates of 6.2% versus 2.3%, respectively (RR 2.7, 95% CI 0.6-12).Conclusion: In women with an incomplete evacuation of the uterus after misoprostol treatment, expectant management is an effective and safe option. This finding could restrain the use of curettage in women that have used misoprostol in the treatment of first trimester miscarriage. (C) 2017 Elsevier B.V. All rights reserved.

Since the first successful live birth after in vitro fertilization (IVF) was reported in 1978, more than 5 million children have been born with the help of this and intracytoplasmic sperm injection (ICSI) procedures. However, only approximately 25% to 30% of cycles of IVF and ICSI lead to the birth of a child. The reasons for implantation failure are poorly understood. One major cause of implantation failure is abnormalities of the uterine cavity such as polyps, myoma, and adhesions. Hysteroscopy has been generally regarded as the standard procedure to detect these uterine abnormalities. It is thought to improve pregnancy rates in women scheduled for IVF by detection and surgical removal of uterine cavity abnormalities, dilatation of the cervical canal, or induction of inflammatory reactions in the endometriumby the procedure itself. Hysteroscopy is often performed routinely in infertile women scheduled for their first IVF cycle. However, there are no data from well-designed randomized controlled trials to support this practice. The inSIGHT trial is a pragmatic multicenter randomized clinical trial designed to determine whether routine hysteroscopy before the first IVF treatment cycle increases the live birth rate. The trial was conducted in 7 university hospitals and 15 large general hospitals in the Netherlands. Women eligible for the trial were infertile, scheduled to start their first IVF or ICSI treatment, had no previous hysteroscopy, and had a normal transvaginal ultrasound of the uterine cavity. Subjects were randomly assigned in a 1: 1 ratio to hysteroscopy with treatment of detected intracavitary abnormalities before starting IVF followed by IVF (hysteroscopy group) or to immediate start of IVF treatment (immediate IVF group). Web-based randomization was done with a variable block size to allocate patients to groups and was stratified by center. The doctors, outcome assessors, and participants were not masked to the assigned group. The primary study outcome was an ongoing pregnancy (detection of a fetal heartbeat at > 12weeks of gestation) within 18 months of randomization and a live birth. Analysis was done according to intention to treat. Between May 25, 2011, and August 27, 2013, 750 women were randomized: 373 to the hysteroscopy group and 377 to the immediate IVF group. A live birth occurred during the trial period in 209 (57%) of 369 women in the hysteroscopy group and 200 (54%) of 373 in the immediate IVF group; the relative riskwas 1.06, with a 95% confidence interval of 0.93 to 1.20; P = 0.41. These findings demonstrate that hysteroscopy does not improve live birth rates in infertile women scheduled for their first IVF cycle, who have a normal transvaginal ultrasound of the uterine cavity. Therefore, routine hysteroscopy should not be performed in women with a normal transvaginal ultrasound.

Retained surgical sponges have been reported to occur after a diversity of surgical procedures, but transmural migration is a very unusual sequela. This article reports a case in which a retained surgical sponge eroded from the intra-abdominal space into the intestinal lumen, migrated distally, and spontaneously passed with defecation 12 weeks after the cesarean section. We performed a systematic review of the literature in Pubmed and found 64 cases of transmural migration of retained surgical sponges. Sixty-four cases have been reported of transmural migration, mainly after intra-abdominal surgery. The most frequent site of impaction is the intestine (75%), but we also found 2 cases that describe migration into the stomach and 7 into the bladder. Five more cases have been published describing transdiaphragmic migration. Only 4 cases describe a sponge spontaneously expelled through the rectum, whereas more than 93% needed re-intervention. We strongly advise only the use sponges with radiopaque markers during surgery and additional methodical wound/body cavity examination.

To compare obstetrical outcome of twin pregnancies after assisted reproduction with that of natural twin pregnancies.Retrospective national database study.Academic Medical Centre.One thousand ninety-three primiparous mothers registered in the Dutch National Birth Registry who gave birth to a dizygotic (DZ) twin (male/female) in 1994, 1995, and 1996. We compared 613 natural twin pregnancies and 480 twin pregnancies born after assisted reproduction.Gestational length, mode of delivery, mode of presentation of the children, birth weight, APGAR score, congenital anomalies, perinatal mortality rate, highest recorded maternal diastolic blood pressure, and maternal postpartum complications.Rates of perinatal mortality and very premature parturition (29 weeks) were lower in natural twin mothers. Overall, induced DZ twins were born 3.5 days earlier with a lower birth weight and APGAR score compared with controls. Rates of congenital anomalies and incidence of cesarean section were not different. The highest recorded diastolic blood pressure was lower in induced twinning with a 30% lower incidence of diastolic blood pressure90 mm Hg.Obstetric outcome for induced DZ twin pregnancy is less optimal than in natural DZ twin pregnancy. Twinning in assisted reproduction is known for its contribution to the high rate of premature deliveries, but in addition being a subfertile patient undergoing treatment makes an intrinsic contribution to adverse events as well.

Objective: To assess the predictive value of elevated basal FSH concentrations during the initial subfertility workup with respect to fecundity in a general subfertility population with ovulatory menstrual cycles. Design: Nested case-control study. Setting: Fertility center of a university hospital. Patient(s): Fifty subfertile women with basal FSH levels >10.0 IU/L and 50 age-matched controls. Intervention(s): Long-term follow-up (3-7 years). Main Outcome Measure(s): Pregnancies, deliveries, and time to pregnancy. Result(s): Patients with elevated basal FSH levels and controls were comparable with regard to basic characteristics, clinical diagnoses, and subfertility treatment. Long-term follow-up showed that 52% of the women with elevated basal FSH concentrations became pregnant (positive predictive value 48%) versus 62% of the controls, and 42% versus 46% eventually delivered a child, respectively. The mean time to pregnancy was 3.0 years in the elevated-FSH group and 3.4 years in controls. Most of the pregnancies in both groups occurred after spontaneous conceptions. Conclusion(s): The results of this study suggest that screening for elevated basal FSH concentrations is of no additional value in a general subfertility population with ovulatory menstrual cycles.

Study Objective: To evaluate the possible role of inappropriate LH secretion, hyperandrogenism, and hyperinsulinemia in the development of polycystic ovaries (PCO) and the polycystic ovary syndrome. Design: Observational. Setting: General population samples. Participants: 58 adolescents with regular menstrual cycles, 50 with irregular menstrual cycles, and 29 with oligomenorrhea (age 16.7 ± 0.9 years). Interventions: Transabdominal pelvic ultrasonography and vena puncture. Main Outcome Measures: PCO; LH, androstenedione, and testosterone levels; overnight fasting insulin concentrations; and oligomenorrhea. Results: The prevalence of PCO increased significantly with the irregularity of the menstrual cycle pattern, as illustrated by the study, finding PCO in 9% of the girls with regular menstrual cycles, 28% of those with irregular menstrual cycles, and 45% of oligomenorrheic girls. The LH and androgen concentrations were significantly higher in girls with PCO; the insulin levels and the glucose–insulin ratio did not differ when the girls with PCO were compared with girls with normal ovaries. Oligomenorrheic girls with PCO had the highest androgen and LH concentrations; their insulin concentrations and glucose–insulin ratio were in the same range as girls with regular menstrual cycles and normal ovaries; and both their hip and waist girths were wider, although their waist–hip ratio was normal. Conclusions: PCO in adolescents is associated with irregular menstrual cycles, oligomenorrhea, and/or high androgen and LH levels; but no relationship was found with the insulin level or glucose–insulin ratio. Thus, it is doubtful that hyperinsulinemia is an important factor in the development of PCO or polycystic ovary syndrome.

Contains fulltext : 109739.pdf (Publisher’s version ) (Open Access) ABSTRACT: BACKGROUND: Costs of in vitro fertilisation (IVF) are high, which is partly due to the use of follicle stimulating hormone (FSH). FSH is usually administered in a standard dose. However, due to differences in ovarian reserve between women, ovarian response also differs with potential negative consequences on pregnancy rates. A Markov decision-analytic model showed that FSH dose individualisation according to ovarian reserve is likely to be cost-effective in women who are eligible for IVF. However, this has never been confirmed in a large randomised controlled trial (RCT). The aim of the present study is to assess whether an individualised FSH dose regime based on an ovarian reserve test (ORT) is more cost-effective than a standard dose regime. METHODS/DESIGN: Multicentre RCT in subfertile women indicated for a first IVF or intracytoplasmic sperm injection cycle, who are aged < 44 years, have a regular menstrual cycle and no major abnormalities at transvaginal sonography. Women with polycystic ovary syndrome, endocrine or metabolic abnormalities and women undergoing IVF with oocyte donation, will not be included. Ovarian reserve will be assessed by measuring the antral follicle count. Women with a predicted poor response or hyperresponse will be randomised for a standard versus an individualised FSH regime (150 IU/day, 225-450 IU/day and 100 IU/day, respectively). Participants will undergo a maximum of three stimulation cycles during maximally 18 months. The primary study outcome is the cumulative ongoing pregnancy rate resulting in live birth achieved within 18 months after randomisation. Secondary outcomes are parameters for ovarian response, multiple pregnancies, number of cycles needed per live birth, total IU of FSH per stimulation cycle, and costs. All data will be analysed according to the intention-to-treat principle. Cost-effectiveness analysis will be performed to assess whether the health and associated economic benefits of individualised treatment of subfertile women outweigh the additional costs of an ORT. DISCUSSION: The results of this study will be integrated into a decision model that compares cost-effectiveness of the three dose-adjustment strategies to a standard dose strategy. The study outcomes will provide scientific foundation for national and international guidelines. TRIAL REGISTRATION: NTR2657.

The possibilities and limitations of basal body temperature (BBT) records as an adjunct in the management of infertility were re-evaluated. To assess its accuracy as an index of ovulation, 172 charts were analyzed by three different physicians. While the average true positive rate was 90%, the false negative rate was only 2%. The remaining graphs (8%) were classified as non-interpretable, probably reflecting measurement problems. Retrospective assessment of 210 biphasic records showed the thermal nadir to occur within 1 day of the urinary luteinizing hormone (LH) surge in 75% of the cases, and in 90% when 2 days where considered. This confirms BBT as a relatively accurate guide for retrospective identification of the periovulatory period. Moreover, results of a study conducted to investigate how patients experienced daily recording of BBT graphs suggest that the method is well accepted by a high proportion of women. From all these it appears that there are many indications where BBT graphs can still be applied. Development of new electronic devices may further improve the reliability, acceptability and applications of the BBT records in the fertility investigation.
