The PPOS protocol (Progestin-primed Ovarian Stimulation) involves avoiding ovulation during ovarian stimulation with progesterone. It is a reliable and safe protocol that has been widely used in recent years for in vitro fertilization, as it reduces the number of injections needed during controlled ovarian stimulation and is more cost-effective for patients.
The aim of this study is to compare two methods of ovarian stimulation for in vitro fertilization: the PPOS protocol (Group A) and the conventional protocol with injected antagonists (Group B). The goal is to determine whether both methods are equally effective in obtaining euploid embryos in the context of double ovarian stimulation.
