Abstract Background For patients embarking on in vitro fertilization (IVF) or Intracytoplasmic sperm injection (ICSI), one of the most concerned problems is their chance of a live-birth. The cumulative live birth rate (CLBR) after IVF has been reported in recent years; however these studies were all about conventional IVF strategy, the CLBRs following freeze-all strategy has not been reported. Methods This was a retrospective cohort study. A total of 20687 women undergoing their first and following IVF cycles during the period from January 1, 2007 through March 31, 2016 were included in this study. The primary Outcomes of the present study were presented in three types: the live birth rate per complete cycle, the conservative CLBR and the optimal CLBR. Results The CLBR increased from 50.74% for the first complete cycle to 64.41% after seven complete cycles,and varied by age category. The CLBR after five complete cycles declined from 77.11% for women younger than 31 years, to 8.63% for women older than 40 years. The predictors of live birth over multiple complete cycles for patients embarking on IVF following freeze-all strategy were women’s age and causes of infertility. In the model constructed for patients finishing the first complete cycle, the number of oocyte retrieved at complete cycle one also played an important predictive role. Conclusions Among women undergoing IVF following freeze-all strategy, the CLBR after seven complete IVF cycles was 84.77% if there were no barriers to continue the IVF treatment, with variation by age. Two prediction models were developed to estimate their probability of having a baby over multiple complete IVF cycles with freeze-all strategy among patients before starting IVF and patients after the first complete cycle, which is critical for patients to make treatment decisions and preparations physically, emotionally and financially.

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.
