OBJECTIVE: To evaluate the effect of estradiol addition to progesterone supplementation during the luteal phase on pregnancy and implantation rates in patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. METHODS: In this prospective, randomized study, carried out in an IVF unit of a university hospital, we studied patients who were undergoing IVF/ICSI with controlled ovarian hyperstimulation using agonadotropin-releasing hormone agonist/human recombinant gonadotropin long protocol. The main outcome measures were the pregnancy and implantation rates measured in the two groups. RESULTS: Our results suggest higher pregnancy and implantation rates in IVF/ICSI-ET cycles that were supplemented with estradiol in the luteal phase. CONCLUSIONS:Estradiol supplementation during the luteal phase in women undergoing IVF/ICSI-ET has a beneficial effect on the outcome without (at least, as seems from this study) having any adverse effects.
