Abstract
For all the steps of in vitro fertilization occur successfully, it must be ensured factors as the quality of retrieved oocytes and endometrial receptivity to the embryo. Currently studies have shown that endometrial receptivity can be optimized through the use of dedicated exogenous progesterone for luteal phase support in assisted reproduction cycles. But it is not yet established the benefits of additional use of estradiol in this support. Analyzing pituitary suppression protocols that employ GnRH antagonists, this review will address what the literature published between the years 2000-2016 sheds light on this issue in order to answer the questions about the benefits of supplementation.
