New Ovarian Stimulation With Random Start, Use of Progestin Protocol for Oocyte Donors

Oocyte donation is a cumbersome and demanding procedure, involving an injectable hormonal treatment for an average duration of 12 days, according to the protocols, 1 to several daily injections. The objective of this study is to show that treatments can be simplified without reducing the number of oocytes that have been punctured, by blocking the luteinizing hormone (LH) surge by using oral progesterone and by limiting the number of injections of gonadotropins using corifollitropin alpha, regardless of the start date of the pacing protocol during a natural cycle.
