To compare luteal phase leuprolide acetate (LA) initiated pituitary down regulation followed by human menopausal gonadotropins (hMG) versus clomiphene citrate (CC) and hMG for follicular recruitment and oocyte maturation before in vitro fertilization (IVF). Randomized, prospective comparison in first cycles of IVF. University Hospital, a tertiary referral center offering assisted reproductive technologies. Participants were couples undergoing their first ever cycle of IVF and consenting to participation in the trial. Luteal phase initiated LA/hMG was associated with a lower probability of cycle cancellation, improved folliculogenesis, and a higher probability of embryo transfer (ET) compared with CC/hMG alone. Implantation rates were not different. A higher rate of ET with LA/hMG suggests that gonadotropin-releasing hormone agonist for the induction of folliculogenesis before IVF may be appropriate.
