To investigate the feasibility and predictive factors for same-day discharge (SDD) after robotic hysterectomy (RH) for benign indications to optimize patient selection by incorporating preoperative, intraoperative, and postoperative variables. A single-center retrospective cohort study. Tertiary academic hospital. Patients undergoing RH for benign indications. Patients were designated for SDD by implementing enhanced recovery after surgery protocol. The study included 890 patients who underwent RH for benign indications between the years 2016 and 2021. Of these, 618 (69.4%) were discharged the same day and 272 (30.5%) were admitted for overnight stay. Both groups had similar age (46.4 vs 46.2 years), body mass index (28.3 vs 28.9), and indications for surgery. In multivariable logistic regression, factors that were significant for overnight stay were American Society of Anesthesiologists score 3, Charlson comorbidity index, previous laparotomy, and operative time. Other factors such as surgery start time and preoperative hemoglobin levels were not statistically significant. Postoperative outcomes were comparable for both groups with similar readmission and reoperation rates. The likelihood of SDD after RH in this cohort after implementing enhanced recovery after surgery protocol was almost 70%, and most of the predictive factors for overnight stay were nonmodifiable. Importantly, both groups had similar outcomes after surgery. [ABSTRACT FROM AUTHOR]

Abstract Research question Does the addition of an aromatase inhibitor improve IVF outcomes in women with endometriomas when pretreating them with gonadotrophin-releasing hormone agonists? Design Retrospective two-centre cohort study involving 126 women aged 21–39 years who failed a previous IVF cycle and all subsequent embryo transfers and had sonographic evidence of endometriomas. Women were non-randomly assigned to either 3.75 mg intramuscular depo-leuprolide treatment alone or in combination with 5 mg of oral letrozole daily for 60 days prior to undergoing a fresh IVF cycle. Main outcome measures included clinical pregnancy rate and ongoing pregnancy rate after 24 weeks' gestation. Results Prior to treatment, antral follicle count (AFC), basal serum FSH and endometrioma diameter did not differ between groups. After treatment, AFC differed between letrozole and non-letrozole-treated groups (10.3 ± 2.0 versus 6.4 ± 2.5; P = 0.0001), as did mean endometrioma maximum diameter (1.8 ± 0.4 cm versus 3.2 ± 0.8 cm; P = 0.0001). At IVF, the gonadotrophin dose used was significantly lower in letrozole-treated subjects (2079 ± 1119 versus 3716 ± 1314; P = 0.0001), the number of mature oocytes collected was greater (9.1 ± 2.4 versus 4.0 ± 1.7; P = 0.0001), as were the number of two-pronuclear embryos and number of blastocysts. The clinical pregnancy rate was significantly higher in the letrozole-treated group (50% versus 22%, P = 0.003), as was the live birth rate (40% versus 17%, P = 0.008). Conclusions The combination of depo-leuprolide acetate monthly for 60 days combined with daily letrozole has better clinical outcomes at IVF in women with endometriomas than depo-leuprolide acetate treatment alone.

Women of advanced age present a major challenge for fertility treatments. This study was designed to assess whether poor ovarian response (POR) according to the Bologna criteria is a significant predictor for live birth in women over 40. The outcomes of subsequent IVF cycles were also studied. The results of 1870 fresh IVF cycles in 1212 women were retrospectively analysed. The live birth per cycle was 3.3 times higher (11.61% versus 3.54%, P < 0.001) in good responders with more than three oocytes collected compared with women with less. Ovarian response defined by oocytes collected, but not by the number of follicles, was independently associated with live birth (odds ratio, 2.0; 95% confidence interval, 1.18 to 3.54; P = 0.009). The occurrence of POR in subsequent IVF cycles was only 55%. No differences in live births were found in persistent POR compared with women with at least one good response. A single episode of POR in a first IVF cycle in older women has a limited predictive value for the outcomes of subsequent cycles. POR in women aged 40–43 years, defined by the number of oocytes retrieved, is a predictor for live birth in IVF. [ABSTRACT FROM AUTHOR]

This retrospective cohort study aimed to identify predictive factors for live birth following blastocyst transfer in women aged 40–43, and to compare the cumulative live birth rate (LBR) following elective single blastocyst (eSBT) and double blastocyst (DBT) transfer. The study included 411 women who had fresh blastocyst transfers on day 5. In stepwise logistic regression, independent predictive factors for live birth were: transferring fully expanded blastocysts (Gardner stage ≥3) (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.59–9.71) and transferring two blastocysts compared with a single blastocyst (OR 1.7, 95% CI 1.08–2.9). Maternal age was not found to be significant (OR 0.78, 95% CI 0.62–1.1). When comparing eSBT ( n = 150) with DBT ( n = 151), the DBT group achieved higher LBRs (26.5 versus 19.3%, P = 0.017) and higher multiple births (0 versus 17.5%, P = 0.02). However, the cumulative LBR was similar (28.0 versus 31.1%), with significantly lower multiple births in the eSBT group (0 versus 14.9%, P = 0.03). These results indicate that in women aged 40–43, when fully expanded blastocysts are achieved, maternal age is not a predictor for live birth, and eSBT can be performed without compromising cumulative LBRs.

Objective: To investigate the reproductive outcomes after the use of GnRH agonist (GnRHa) compared with hCG for the induction of final oocyte maturation in GnRH antagonist cycles performed in hyper-responder women aged 35-40 years.Design: Retrospective study.Setting: Academic fertility center.Patient(s): Two hundred seventy-two hyper-responder women aged 35-40 years who underwent controlled ovarian stimulation under GnRH antagonist suppression were included. Final oocyte maturation was performed with GnRHa (n = 168) or hCG (n = 104). Embryos were cryopreserved at the blastocyst stage and transferred in subsequent warming cycles (n = 542). Subjects were included in the analysis until live birth was achieved, after which they were excluded from further analysis.Intervention(s): None.Main Outcome Measure(s): Cumulative live birth rate.Result(s): Subjects in the GnRHa group achieved a higher number of oocytes (22 vs. 21) and a higher number of mature oocytes (16 vs. 14). The number of cryopreserved blastocysts (median of five blastocysts in both groups) was similar. Women in the hCG group needed a lower number of warming cycles to achieve live birth (1.32 vs. 2.12), had higher embryo implantation rates (48% vs. 39%), and the proportion of embryos transferred until live birth was lower (33% vs. 57%). The cumulative live birth rate was similar between the groups (48.15% vs. 48%).Conclusion(s): Although the cumulative live birth rate is similar, a single dose of GnRHa possibly results in suboptimal oocyte and embryo competence, as manifested by decreased embryo implantation rates and increased time needed to achieve live birth.

Objective: To compare the influence of dual suppression with the use of GnRH agonist plus aromatase inhibitor compared with suppression with the use of GnRH agonist alone or no suppression at all in patients with idiopathic recurrent implantation failure (RIF).Design: Retrospective cohort study.Setting: University-affiliated reproductive center.Patient(s): A total of 523 infertile women who failed two blastocyst transfers underwent a third frozen blastocyst transfer. Women with known endometriosis were excluded.Intervention(s): A total of 204 subjects were not pretreated, 143 received 2 months of GnRH agonist (3.75 mg intramuscular leuprolide acetate monthly) only, and 176 received GnRH agonist and aromatase inhibitor (5 mg oral letrozole daily for 60 days). Demographic and stimulation information was collected and cycle outcomes reported.Main Outcome Measure(s): Clinical pregnancy rates.Result(s): Age, antral follicle count, basal FSH levels, duration of infertility, previous pregnancies, and full-term deliveries were similar (P>.05). Clinical pregnancy rates were higher among women who received GnRH agonist plus letrozole compared with women who received GnRH agonist only or women without pretreatment (63%, 42%, and 40%, respectively; P<.0001). Live birth rates were higher among women who received GnRH agonist plus letrozole compared with the other groups (56%, 36%, and 34%; P<.0001). No differences in pregnancy outcomes were noted between patients who did not receive pretreatment and those in the GnRH agonist only group.Conclusion(s): In patients with RIF, treatment with a GnRH agonist plus letrozole may improve live birth rates in subsequent cycles. We hypothesize that this improvement is due to alterations in the endometrium receptivity or treatment of undiagnosed endometriosis. [ABSTRACT FROM AUTHOR]

Do uterine size parameters measured by baseline transvaginal ultrasound predict live birth after single embryo transfer (SET) of a high-quality blastocyst? Retrospective cohort study including women undergoing their first SET between August 2010 and March 2014 at a large university hospital reproductive centre. The effects of baseline uterine dimensions on live birth rate (LBR) were analysed while controlling for confounding effects. A total of 437 nulliparous and 70 parous women were included. The nulliparous group had lower body mass index (BMI) (24.4 ± 5.1 versus 25.9 ± 4.5 kg/m2; P = 0.015) and a higher number of fibroids (0.4 ± 1.0 versus 0.2 ± 0.5; P = 0.005) than the parous group. While controlling for confounding effects, none of the uterine parameters appeared to be a significant predictor of LBR among nulliparous and parous women (P > 0.05 in all cases). A subsequent analysis of endometrial length was done, whereby the endometrial lengths were divided into quartiles (20.0–32.2 mm; 32.3–36.5 mm; 36.6–40.0 mm; 40.1–54.0 mm). After controlling for confounders, the shortest quartile in the nulliparous group had a significantly lower LBR (P = 0.02) than the other groups. Receiver operating characteristic curves suggested that endometrial cavity length and cervical length did not aid clinically. Uterine parameters do not have a clinically useful impact on LBR after SET of a blastocyst in infertile women. The use of baseline endometrial length to predict live birth is no better than chance, while cervical length only predicts failure to live birth. [ABSTRACT FROM AUTHOR]

Does the addition of a gonadotrophin-releasing hormone (GnRH) antagonist to cabergoline treatment during the luteal phase in fresh IVF cycles triggered with a GnRH agonist, and planned for freeze-all, reduce the rate of mild and moderate ovarian hyperstimulation syndrome (OHSS)? Retrospective cohort study of 480 IVF patients at risk for OHSS with GnRH agonist trigger from 2011 to 2018, stratified into three groups based on treatment received: GnRH agonist trigger alone (Group 1, n = 208), GnRH agonist trigger + cabergoline (Group 2, n = 167) or GnRH agonist trigger + cabergoline + GnRH antagonist (Group 3, n = 105). Data on patient demographics, incidence, severity and symptomatology of OHSS and laboratory findings were collected. Group 1 had more free peritoneal fluid than Group 2 (28% versus 19%, P = 0.04) or Group 3 (28% versus 5%, P = 0.001). Group 1 reported abdominal discomfort and bloating more than Group 2 (33% versus 21%, P = 0.01) or Group 3 (33% versus 18%, P = 0.006). Group 1 had more electrolyte abnormalities than Group 2, who had more than Group 3. No patients developed severe OHSS. Mild and moderate OHSS rate was higher in Group 1 (38%) than Group 2 (29%, P = 0.048) or Group 3 (18%, P = 0.006) and in Group 2 than Group 3 (P = 0.046). Addition of cabergoline to GnRH agonist triggering in high-risk OHSS patients, and subsequent addition of GnRH antagonist for 5 days in the luteal phase, sequentially reduces the risk of mild and moderate OHSS and improves patient comfort compared with GnRH agonist trigger alone.
