Abstract:
Evaluation of the optimal number of embryos, their quality, and the precise timing for transfer are critical determinants in reproductive success, although still remaining one of the main challenges in assisted reproduction technologies (ART). Indeed, the success of in vitro fertilization (IVF) treatments relies on a multitude of events and factors involving both the endometrium and the embryo. Despite concerted efforts on both fronts, the overall success rates of IVF techniques continue to range between 25% and 30%. The role of the endometrium in implantation has been recently recognized, lea

Abstract:
In assisted reproduction treatments (ART), applying the ICSI method for fertilization of oocytes rather than traditional IVF method, is regarded as controversial for two reasons, namely utility and safety. Our study examines an IVF-ICSI Split model for couples with unexplained infertility, where male factor is meticulously excluded and ART is conducted by a strict algorithm, a commitment to blastocyst culture, along with single embryo transfers and a high commitment to cryopreservation. From 242 treatment cycles, 3346 oocytes recovered (13.8 per OPU) were randomly allocated to IVF or ICSI and
