About

The aim of this study is to compare the efficacy and safety of Progestin-Primed Ovarian Stimulation (PPOS) protocol versus the fixed GnRH antagonist protocol in expected normal responder patients undergoing intracytoplasmic sperm injection (ICSI) with frozen-thawed embryo transfer (FET). By evaluating key clinical outcomes, including ovarian response, embryological parameters, and pregnancy rates, this study seeks to determine the relative advantages and limitations of each protocol.

Full description

In this prospective, non-inferiority trial, we will compare the efficacy and safety of the GnRH antagonist and PPOS protocols in 328 infertile women undergoing ICSI in Kasr Al-Ainy IVF department, Cairo University, Egypt. Before the trial, investigators were required to provide all information related to the clinical trial, including the possible benefits and risks, other therapeutic choices and the right to withdraw, via a written consent. After being provided with sufficient time to decide whether to participate and the opportunity to ask questions, all participants were required to provide written informed consent before study inclusion.
