Prospective, randomized, comparative study of leuprorelin + human menopausal gonadotropins versus ganirelix + recombinant follicle-stimulating hormone in oocyte donors and pregnancy rates among the corresponding recipients

Abstract

Treating oocyte donors with leuprorelin + hMG produces among recipients a greater probability of clinical pregnancy per embryo transfer than when donors are treated with ganirelix + rFSH; however, more cycles are cancelled and the former treatment is more unpleasant for donors.
