title: Randomized, comparative pilot study of pituitary suppression with depot leuprorelin versus cetrorelix acetate 3 mg in gonadotropin stimulation protocols for oocyte donors.
abstract: In a pilot study, implantation and pregnancy rates per transfer were favorable in recipients of donated eggs treated with a single dose of cetrorelix acetate 3 mg compared with recipients of donated eggs treated with the long protocol (42.3% vs. 30.5%, and 71.0% vs. 46.7%, respectively; NS). The stimulation protocol based on gonadotropins and a single dose of cetrorelix acetate 3 mg is adequate in terms of safety and comfort of donors and the likelihood of pregnancy among recipients, although these favorable results require confirmation in future studies.
