Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The inclusion criteria of the study were: first cycle of ART treatment with conventional IVF or ICSI with donated eggs, normal uterine cavity and a single or double embryo transfer, always performed on day 5 at blastocyst stage.
The exclusion criteria were the following: patients above 50 years old, patients that were diagnosed with recurrent implantation failure (RIF) and/or recurrent pregnancy loss (RPL) or uterine pathologies, body mass index \>30 kg/m2, the use of seminal samples coming from donors or testicular origin and cycles that included preimplantational genetic testing (PGT).
LBR was the main outcome of our study, defined as the number of deliveries that resulted in a live born neonate, expressed per 100 embryo transfers (Zegers- Hochschild et al., 2009). Secondary efficacy endpoints were positive hCG rate (\>5 mUI/mL, assessed in serum 14 days after oocyte retrieval), implantation rate (number of gestational sacs observed divided by the number of embryos transferred, expressed as a percentage, %), ongoing pregnancy rate, defined as a pregnancy with a detectable heart rate at 12 weeks of gestation or beyond and miscarriage (loss of a pregnancy after 12 weeks of gestation).
In addition, we assessed the next IVF laboratory parameters: fertilization rate, blastocyst formation rate on day 5, blastocyst quality, number of transferred embryos and number of usable blastocysts (number of blastocysts transferred and frozen).
The sample size calculation was based on the primary outcome. We assumed a live birth rate of 40% in the control group, compared to 50% in the non-observational group deduced from previous studies. By applicating the sample size calculation program, 776 patients (388 per group) were required in order to detect a risk difference (RD) of 10% between the two groups in the final analysis, with a power of 80% at a two-sided, adjusted alpha-level of 0.05. A follow-up loss rate of 10% was estimated.
