The Effect of Follitropin Alfa in Controlled Ovarian Stimulation Protocol for In Vitro Fertilization Cycles.

Background: Follitropin alfa (FA) is one of the most widely used exogenous gonadotropins in both agonist and antagonist protocols for controlled ovarian stimulation (COS) and in vitro fertilization (IVF). However, reports of its effectiveness are limited, particularly in terms of its impact on overall IVF outcomes and ovarian hyperstimulation syndrome (OHSS). Therefore, in this study, FA competency was investigated by evaluating its effect on IVF outcomes and OHSS, administering agonist and antagonist COS protocols.
