title: Does day 3 luteinizing-hormone level predict IVF success in patients undergoing controlled ovarian stimulation with GnRH analogues?
abstract: To examine whether day 3 LH level or FSH-LH ratio predict IVF outcome, we studied patients with a favorable prognosis a priori undergoing controlled ovarian hyperstimulation (COH) with GnRH agonist (agonist group; n = 131) or antagonist (antagonist group; n = 137). Although LH level could not predict IVF outcome, patients undergoing COH using the GnRH antagonist or agonist protocols with FSH-LH ratios >2 or >3, respectively, achieved significantly lower pregnancy rates (11.1% vs. 27.7% and 8.3% vs. 31.9%, respectively).
