A novel method of luteal supplementation with recombinant luteinizing hormone when a gonadotropin-releasing hormone agonist is used instead of human chorionic gonadotropin for ovulation triggering: a randomized prospective proof of concept study

This pilot study investigates the role of luteal supplementation with recombinant LH in an attempt to reverse the poor reproductive outcome previously noticed after GnRH-agonist triggering of final oocyte maturation for IVF. Similar implantation rates were achieved with the novel recombinant LH luteal supplementation scheme compared with the standard luteal P protocol (25.0% vs. 26.7%, respectively). No cases of ovarian hyperstimulation syndrome (OHSS) were noticed in either group. (Fertil Steril (R) 2011;95:1174-7. (C) 2011 by American Society for Reproductive Medicine.)
