Abstract Background: Cumulative live birth rate (CLBR) becomes a comprehensive and meaningful indictor of the success of IVF nowadays. Frozen-embryo transfer (FET) was associated with a higher rate of live birth and a lower risk of the ovarian hyperstimulation syndrome (OHSS) in polycystic ovary syndrome (PCOS) patients. Progestin-primed ovarian stimulation (PPOS) is a new ovarian stimulation protocol in which oral progestin been used to prevent premature luteinizing hormone (LH) surges during ovarian stimulation. The purpose of the current study is to investigate the CLBR of an in vitro fertilization (IVF) cycle in women with PCOS following PPOS protocol compared with gonadotropin releasing hormone (GnRH) antagonist protocol.Methods: It is a retrospective study. The first IVF cycle of 666 PCOS women were included. Ovarian stimulations were performed with PPOS or GnRH antagonist protocol. All patients included in the analysis had either delivered a baby or had used all their embryos of their first stimulated cycle. The patients were followed for 2–7 years until February 2020.Result(s): The CLBR were similar in the PPOS and GnRH antagonist group (64% vs 60.1%, P = 0.748). Logistic regression analyses showed treatment protocol (PPOS vs GnRH antagonist) did not show any significant correlation with the CLBR (adjusted OR: 0.898; 95% CI: 0.583-1.384, P=0.627). No statistically significant differences were found in the live birth rates per embryo transfer (41.3% vs. 38.4%) in the study group and controls.Conclusion(s): The results of this study showed that both the live birth rate per embryo transfer and the cumulative live birth rate were similar between PPOS and GnRH antagonist group. PPOS protocol is efficient in the controlled ovarian stimulation of patients with PCOS.

ObjectiveTo explore the association between serum LH levels and the cumulative live birth rate (CLBR) within one complete cycle, and the impact of serum LH levels on the live birth rate (LBR) after the initial embryo transfer (ET) considering different ET strategies (fresh or freeze-all).DesignA retrospective cohort study.SettingUniversity-affiliated reproductive center.Patients1480 normogonadotrophic women who underwent COS with GnRH antagonist protocol for the first IVF/ICSI attempt.Intervention(s)The sample was stratified into low and higher LH groups according to serum LH peak levels of <4 (Group A) and ≥4 IU/L (Group B) during COS. Patients were also sub-grouped into conventional fresh/frozen ET cycles and freeze-all cycles.Main outcome measure(s)The LBR after the initial embryo transfer and the CLBR within one complete cycle.Secondary outcome measure(s)The numbers of day-3 high-quality embryos, the numbers of embryos available, and the other pregnancy outcomes after the initial ET.Result(s)In the whole cohort, the CLBRs decreased significantly in the low (63.1% vs. 68.3%, P=.034) LH group compared to the higher LH group. Subgroup analysis revealed that patients with low LH levels had lower LBR after fresh ET (38.0% vs. 51.5%, P=.005) but comparable LBR after the first frozen-thawed ET (FET) in freeze-all cycles (49.8% vs. 51.8%, P=.517) than patients with higher LH peak levels. Likewise, patients with low LH levels had lower CLBR for conventional fresh/frozen ET cycles (54.8% vs. 66.1%, P=.015) but comparable CLBR for the freeze-all cycles (66.8% vs. 69.2%, P=.414) than those with higher LH levels. Following confounder adjustment, multivariable regression analyses showed that low LH level was an independent risk factor for the CLBR in the whole cohort (odds ratio (OR): 0.756, 95% confidence interval (CI): 0.604-0.965, P=.014) and in patients who underwent the conventional ET strategy (OR: 0.596, 95% CI: 0.408-0.917, P=.017). Moreover, the adverse impact of low LH levels on LBRs maintained statistically significant after fresh transfers (OR: 0.532, 95% CI: 0.353-0.800, P=.002) but not after the first FETs in freeze-all cycles (OR: 0.918, 95% CI: 0.711-1.183, P=.508).Conclusion(s)In comparison with higher LH levels, low LH levels decrease the CLBRs per oocyte retrieval cycle for normogonadotrophic women who underwent COS using GnRH antagonists. This discrepancy may arise due to the significant detrimental effect of low LH levels on the LBRs after fresh embryo transfers.

Cumulative Live Birth

This is a retrospective cohort study included 1021 patients underwent a flexible GnRH antagonist IVF protocol from January 2017 to December 2017 to explore the effect of a premature rise in luteinizing hormone (LH) level on the cumulative live birth rate. All patients included received the first ovarian stimulation and finished a follow-up for 3 years. A premature rise in LH was defined as an LH level >10 IU/L or >50% rise from baseline during ovarian stimulation. The cumulative live birth rate was calculated as the number of women who achieved a live birth divided by the total number of women who had either delivered a baby or had used up all their embryos received from the first stimulated cycle. In the advanced patients (≥37 years), the cumulative live birth rate was reduced in patients with a premature rise of LH (β: 0.20; 95% CI: 0.05–0.88; p=0.03), compared to patients (≥37 years) without the premature LH rise. The incidence of premature LH rise is associated with decreased rates of cumulative live birth rate in patients of advanced age (≥37 years) and aggravated the reduced potential of embryos produced by the advanced age, not the number of embryos.

Abstract Context Supraphysiological estradiol exposure after ovarian stimulation may disrupt embryo implantation after fresh embryo transfer. Women with polycystic ovary syndrome (PCOS), who usually overrespond to ovarian stimulation, have a better live birth rate after frozen embryo transfer (FET) than after fresh embryo transfer; however, ovulatory women do not. Objective To evaluate whether the discrepancy in live birth rate after fresh embryo transfer vs FET between these two populations is due to the variation in ovarian response (i.e., peak estradiol level or oocyte number). Design, Setting, Patients, Intervention(s), and Main Outcome Measure(s) This was a secondary analysis of data from two multicenter randomized trials with similar study designs. A total of 1508 women with PCOS and 2157 ovulatory women were randomly assigned to undergo fresh or FET. The primary outcome was live birth. Results Compared with fresh embryo transfer, FET resulted in a higher live birth rate (51.9% vs 40.7%; OR, 1.57; 95% CI, 1.22 to 2.03) in PCOS women with peak estradiol level >3000pg/mL but not in those with estradiol level ≤3000 pg/mL. In women with PCOS who have ≥16 oocytes, FET yielded a higher live birth rate (54.8% vs 42.1%; OR, 1.67; 95% CI, 1.20 to 2.31), but this was not seen in those with <16 oocytes. In ovulatory women, pregnancy outcomes were similar after fresh embryo transfer and FET in all subgroups. Conclusions Supraphysiological estradiol after ovarian stimulation may adversely affect pregnancy outcomes in women with PCOS but not in ovulatory women.

Abstract Background Synchronization of follicles is key to improving ovulation stimulation with the gonadotropin-releasing hormone (GnRH) antagonist protocol. GnRH antagonist administration in the early follicular phase can quickly decrease gonadotrophin (Gn) levels and achieve downregulation before stimulation, which may improves synchronization. A previous small randomized controlled study (RCT) showed that pretreatment with a GnRH antagonist for 3 days before stimulation may increase oocyte retrieval but cannot increase the pregnancy rate. This study investigated whether the GnRH antagonist pretreatment protocol in ovulatory women can increase the synchronization of follicles and pregnancy outcomes compared with the conventional GnRH antagonist protocol. Methods This RCT included 136 normal ovulatory women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). Both groups were treated with recombinant follicle-stimulating hormone (r-FSH) and a flexible GnRH antagonist protocol. The women were randomized into two equal groups with or without GnRH antagonist administration from day 2 of the menstrual cycle for 3 days before stimulation. Our primary outcome was the number of retrieved oocytes. Secondary outcomes included the pregnancy rate and live birth rate. Results Both groups had similar baseline characteristics. The number of retrieved oocytes in the study group was comparable to that in the control group (9.5 [8.0–13.0] vs. 11.0 [7.0–14.8], P = 0.469). There was no significant difference in the follicle size. The fertilization rate, number of good-quality embryos, implantation rate, pregnancy rate, ongoing pregnancy rate, live birth rate per embryonic transfer cycle, and miscarriage rate were similar between the two groups. Conclusion This large RCT analysed GnRH antagonist pretreatment with the GnRH antagonist protocol applied to normal ovulatory women undergoing IVF/ICSI. The number of retrieved oocytes and pregnancy outcomes did not significantly vary. Trial registration Chinese Clinical Trial Registry, ChiCTR1800019730. Registered 26 November 2018.

Abstract Background The overall cumulative live birth rate (CLBR) of poor ovary responders (POR) is extremely low. Minimal ovarian stimulation (MOS) suggested a relative realistic solution in ART for POR. Our study aimed to investigate whether multiple MOS strategy results in higher CLBR compared to GnRH antagonist protocol and the cost-effectiveness analysis in POR. Methods This retrospective study involved 699 patients (1058 cycles) who fulfilled the Bologna criteria in one center performed from 2010–2018. Specifically, 325 women (325 cycles) were treated with one time conventional GnRH antagonist ovarian stimulation (GnRH-antagonist). Another 374 patients (733 cycles) were treated with multiple minimal ovarian stimulations (MOS) including natural cycles. CLBR and cost-effectiveness analysis were performed comparing these two groups of women. Results GnRH- antagonist leads to more oocytes retrieved, more fertilized oocytes and more viable embryos compared to first MOS (p < 0.001) and the cumulative corresponding ones in multiple MOS (p < 0.001). For the first IVF cycle, GnRH- antagonist results in higher CLBR than MOS (12.92% versus 4.54%, Adjusted OR 2.606; 95%CI 1.386, 4.899, p = 0.003). However, GnRH-antagonist induces comparable CLBR with multiple MOS (12.92% versus 7.92%, Adjusted OR 1.702; 95%CI 0.971, 2.982, p = 0.063), but absolutely shorter time to live birth (9 (8, 10.75) months versus 11 (9, 14) months, p = 0.014) and similar financial expenditure compared to repeated MOS (20838 (17953, 23422) ¥ versus 21261.5 (15892.5, 35140.25) ¥, p = 0.13). Conclusion Both MOS and GnRH-antagonist provide low chance of live birth for poor responders. GnRH antagonist protocol is a sound choice for POR with comparable CLBR, shorter time to live birth and similar financial expenditure.

Superiority Trial

IntroductionIn vitro fertilisation (IVF) has evolved as an intervention of choice to help couples with infertility to conceive. In the last decade, a strategy change in the day of embryo transfer has been developed. Many IVF centres choose nowadays to transfer at later stages of embryo development, for example, transferring embryos at blastocyst stage instead of cleavage stage. However, it still is not known which embryo transfer policy in IVF is more efficient in terms of cumulative live birth rate (cLBR), following a fresh and the subsequent frozen–thawed transfers after one oocyte retrieval. Furthermore, studies reporting on obstetric and neonatal outcomes from both transfer policies are limited.Methods and analysisWe have set up a multicentre randomised superiority trial in the Netherlands, named the Three or Fivetrial. We plan to include 1200 women with an indication for IVF with at least four embryos available on day 2 after the oocyte retrieval. Women are randomly allocated to either (1) control group: embryo transfer on day 3 and cryopreservation of supernumerary good-quality embryos on day 3 or 4, or (2) intervention group: embryo transfer on day 5 and cryopreservation of supernumerary good-quality embryos on day 5 or 6. The primary outcome is the cLBR per oocyte retrieval. Secondary outcomes include LBR following fresh transfer, multiple pregnancy rate and time until pregnancy leading a live birth. We will also assess the obstetric and neonatal outcomes, costs and patients’ treatment burden.Ethics and disseminationThe study protocol has been approved by the Central Committee on Research involving Human Subjects in the Netherlands in June 2018 (CCMO NL 64060.000.18). The results of this trial will be submitted for publication in international peer-reviewed and in open access journals.Trial registration numberNetherlands Trial Register (NL 6857).

Objective: In the present study, we aimed to retrospectively evaluate the cumulative live birth rate (LBR) after up to three consecutive embryo transfer (ET) cycles, either fresh or frozen, in women with expected poor ovarian response (ePOR). Methods: We selected 115 women who entered the first <i>in vitro</i> fertilization (IVF) cycle between August 2013 and July 2016. The women were divided into an ePOR group (37 women) and a non-ePOR group (78 women). All women in the ePOR group were ≥40 years old or had serum anti-Müllerian hormone levels of less than 1.1 ng/mL at the time of the first IVF cycle. Live birth outcomes were monitored until December 2017. The cumulative LBR (with both conservative and optimistic estimates) was calculated according to the serial number of ET cycles. Results: After up to three ET cycles, the overall cumulative LBR was significantly lower in the ePOR group than in the non-ePOR group (conservative estimate, 10.8% vs. 44.9%, respectively; optimistic estimate, 14.7% vs. 56.1%, respectively; log-rank test, <i>p</i>=0.003). Conclusion: Women with ePOR exhibited a lower cumulative LBR than women in the non-ePOR group, and this information should be provided to ePOR women during counseling before starting IVF.

Abstract Background: Women with polycystic ovary syndrome (PCOS) have been reported with low pregnancy rate and high OHSS risk in in vitro fertilization (IVF) programs due to the decreased endometrial receptivity and high ovarian reserve. The aim of the study was to compare the effectiveness, safety and economic cost of GnRH antagonist (GnRH-ant) and modified prolonged GnRH agonist (mGnRH-a) protocol in PCOS patients.Methods: This study was a retrospective cohort study that included 2164 women with (PCOS) undergoing assisted reproductive technology (ART) treatment from January 2014 to April 2019. Among them, 2018 women received mGnRH-a treatment and 146 women received GnRH antagonist (GnRH-ant) treatment. The two groups were matched by propensity scores with a ratio of 1:4 (GnRH-ant versus mGnRH-a) accounting for potential confounding factors. The primary outcomes were the live birth rate (LBR), incidence of moderate-to-severe OHSS and the cost of controlled ovarian hyperstimulation (COH). LBR was defined as live birth per started treatment cycle after first fresh or frozen embryo transfer.Results: Women with the mGnRH-a protocol had an increased endometrial thickness on HCG injection day, compared with GnRH-ant protocol (10.84 vs. 9.62, P<0.001), furthermore, the number of transferable embryos on day 3 (7 vs. 5, P=0.022), clinical pregnancy rate (67.81% vs. 52.74%, P=0.0007), implantation rate (56.05%, vs. 43.44%, P<0.001) and live birth rate (58.22% vs. 41.78%, P=0.0004) were also significantly higher in the mGnRH-a protocol group. However, there were no significant differences in the incidence of moderate-to-severe OHSS (4.28% vs. 2.05%, P=0.333), the incidence of severe OHSS (0.17% vs. 0%, P=1) and the cost of COH (RMB: 7736.9 vs. 8046.54, P=0.113). Conclusion: The mGnRH-a protocol has a higher live birth rate than GnRH-ant protocol with the similar safety and economic cost among infertile women with PCOS.
