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 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.

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.

Abstract Background: The efficacy and reproductive outcomes of progestin primed ovarian stimulation protocol (PPOS) were previously compared to rarely used ovarian stimulation protocol and also the live birth rate were reported by per embryo transfer rather than cumulative live birth rates (CLBRs). Does the use of PPOS improve the cumulative live birth rates (CLBRs) and shorten time to live birth when compared to long GnRH agonist protocol in women with normal ovarian reserve?Methods: A retrospective cohort study was designed to include women aged<40 with normal ovarian reserve (regular menstrual cycles, FSH <10 IU/L, antral follicle count >5) undergoing IVF from January 2017 to December 2019. The primary outcome was cumulative live birth rates (CLBRs) within 18 months from the day of ovarian stimulation.Results: A total of 995 patients were analyzed. They used either PPOS (n=509) or long GnRH agonist (n=486) protocol at the discretion of the attending physicians. Both groups had almost comparable demographic and cycle stimulation characteristics except for duration of infertility which was shorter in the PPOS group. In the GnRH agonist group 372 cases (77%) completed fresh embryo transfer, resulting into 218 clinical pregnancies and 179 live birth. The clinical pregnancy rate, ongoing pregnancy, and live birth per transfer were 58.6%, 54.0%, 53.0% respectively. In the PPOS, no fresh transfer was carried out. During the study period, the total number of initiated FET cycles with thawed embryos was 665 in the PPOS group and 259 in the long agonist group. Of all FET cycles, a total of 206/662 (31.1%) cycles resulted in a live birth in the PPOS group versus 110/257 (42.8%) in the long agonist group (OR: 0.727; 95% CI: 0.607–0.871; p<0.001) .The implantation rate of total FET cycles was also lower in the PPOS group compared with that in the agonist group 293/1004 (29.2%) and 157/455 (34.5%) (OR: 0.846; 95% CI: 0.721–0.992; p= 0.041). Cumulative live birth rates after one complete IVF cycle including fresh and subsequent frozen embryo cycles within 18 months follow up were significantly lower in the PPOS group compared that in the long agonist group 206/509 (40.5%) and 307/486 (63.2%), respectively (OR: 0.641; 95% CI: 0.565-0.726). The average time from ovarian stimulation to pregnancy and live birth was significantly shorter in the long agonist group compared to the PPOS group (p<0.01) In Kaplan-Meier analysis, the cumulative incidence of ongoing pregnancy leading to live birth was significantly higher in the long agonist compared in the PPOS group(Log rank test, p<0.001). Cox regression analysis revealed stimulation protocol adopted was strongly associated with the cumulative live birth rate after adjusting other confounding factors (OR =1.917 (1.152-3.190), p=0.012) .Conclusion: Progestin primed ovarian stimulation was associated with a lower cumulative live birth rates and a longer time to pregnancy / live birth than the long agonist protocol in women with a normal ovarian reserve.

Abstract Study question To compare the live birth rate using frozen-thawed blastocysts obtained from ovarian stimulation with individualised follitropin delta dosing to conventional follitropin alfa dosing. Summary answer The live birth rate in cryo cycles conducted within 1 year after ovarian stimulation was comparable for individualised follitropin delta and conventional follitropin alfa treatment. What is known already It has been demonstrated that the follitropin delta (Rekovelle, Ferring Pharmaceuticals) in an individualised dosing regimen based on anti-Müllerian hormone (AMH) level and body weight is non-inferior to conventional follitropin alfa (Gonal-f, Merck Serono) dosing with respect to ongoing pregnancy and ongoing implantation rates in fresh cycles. The individualised approach also reduced the risk of ovarian hyperstimulation syndrome (OHSS) versus the conventional approach. Furthermore, treatment with follitropin delta and follitropin alfa gave comparable pregnancy rates in repeated fresh cycles. Study design, size, duration Analysis of frozen cycles using blastocysts obtained from a randomised trial comparing follitropin delta versus follitropin alfa in 1,326 IVF/ICSI patients (18–40 years) and a subsequent trial of up to two additional ovarian stimulation cycles. The clinical outcome includes women with cryopreserved blastocysts following ovarian stimulation and who underwent frozen cycles within 1 year after starting stimulation in their last cycle. Participants/materials, setting, methods A total of 917 women had at least one Day 5 blastocyst which was vitrified and stored following up to three ovarian stimulation cycles. A started cryo cycle was defined as warming of a blastocyst. After warming, 1–2 blastocysts were transferred in cryo cycles, using natural cycle or programmed regimens. Treatment differences and 95% confidence intervals (CI) were calculated with adjustment for age strata and accounting for repeated cycles within patient. Main results and the role of chance The proportion of women with frozen blastocysts was similar in the two treatment groups, with 69.5% in the follitropin delta group and 68.8% in the follitropin alfa group. Similar postwarming blastocyst survival rates were observed for the two groups, with 87.4% of the warmed blastocysts proceeding to transfer in the follitropin delta group and 88.8% in the follitropin alfa group. About half of the women (48.1% in each treatment group) with frozen blastocysts underwent at least one frozen cycle with transfer within the 1-year period, with an average of 1.5 cycles per woman in the follitropin delta group and 1.6 cycles per woman in the follitropin alfa group. The ongoing implantation rate was 27.6% in the follitropin delta group and 27.8% in the follitropin alfa group (adjusted difference 0.5% [95% CI: –7.1%; 8.2%]). The live birth rate per started cryo cycle was 32.0% in the follitropin delta group and 31.3% in the follitropin alfa group (adjusted difference 1.2% [95% CI: –6.8%; 9.3%]), while the live birth rate per cryo cycle with transfer was 33.2% and 31.9% (adjusted difference 1.9% [95% CI: –6.2%; 10.0%]), respectively. Limitations, reasons for caution The number of blastocysts to be transferred in the frozen cycles as well as the protocol for endometrial preparation was based on local centre practices. Wider implications of the findings: These findings suggest that the follitropin delta and follitropin alfa dosing regimens are equally effective in terms of live birth rate in frozen replacement cycles and add reassuring information to the clinical performance of cryopreserved blastocysts derived from ovarian stimulation with follitropin delta.
