Usefulness of Medroxyprogesterone Acetate in Follicular Phase in Oocyte Donors. Undergoing Ovarian Stimulation

Infertility Clinical Trial

Official title: Usefulness of Medroxyprogesterone Acetate in Follicular Phase in Oocyte Donors.

Status Completed

Clinical Trial Summary

The purpose of this study is to determine whether Medroxyprogesterone Acetate (MPA) administration in follicular phase prevents premature luteinization with equal efficiency as GnRH antagonists and otains similar clinical results in oocyte donation.

Clinical Trial Description

Within the new guidelines for stimulation, the use of oral progesterone in follicular phase allows GnRH analogue administration, resulting in greater comfort for patients as well as a reduction in cost. Obtained results are similar to those from conventional protocols in terms of: early luteinization, number of oocytes, embryos number and rate of implantation and gestation or appearance of congenital malformations. Another advantage is the lower incidence of OHSS (Ovarian Hyperstimulation Syndrome). From a scientific point of view, it would allow a better understanding of folliculogenesis, of progesterone mechanism of action on blocking LH secretion and its effect on ovarian and later embryonic level. From a clinical point of view, it would simplify COS (Controlled Ovarian Stimulation) by reducing the number of medication administered subcutaneously and their possible side effects on both systemic and local levels. It would be of special interest in 2 groups of patients, for example, oocyte donors and patients undergoing preservation of fertility. To date, there is a lack of studies along these lines. ;
