Study summary

What the protocol is testing.

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.

Full detailed 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.

Interventions

Treatment arms and agents.

DRUG

Provera 10 mg.

One 10 mg tablet of MPA (Medroxyprogesterone acetate) is administered every 24 hours from the onset of Controlled Ovarian Stimulation (COS), until the day of triggering.

DRUG

Ganirelix (GnRH antagonist)

One ampoule of Ganirelix (GnRH antagonist) a day once diameter of follicles are 14 mm diameter on average until triggering.
