Abstract:

Adequate availability and FSH sensitivity of ovarian antral follicles, and coordination of their growth during controlled ovarian stimulation (COS), are two important factors that play a decisive role in pregnancy outcome. Growing evidence indicates that steroid hormone pretreatments may positively improve both factors by inhibiting or weakening the early rise of FSH at luteal phase. However, there is a lack of consensus on whether the conventional pretreatment with combined oral contraceptive pills (COCP), estrogen or progestin alone before COS will increase the IVF pregnancy rate and live birth rate. This article summarizes the clinical research progress of related topics in recent years, including the application of COCP, estrogen and progesterone pretreatment in different types of patients and different ovarian stimulation protocols, and the impact of hormonal pretreatment on the outcomes of assisted reproduction technology.
