Abstract

To evaluate the effects of a gonadotropin-releasing hormone (GnRH) antagonist protocol, with or without oral contraceptive pill (OCP) pretreatment, in patients with polycystic ovary syndrome (PCOS) undergoing intracytoplasmic sperm injection (ICSI).In this retrospective cohort study, 410 infertile patients with PCOS were assessed in their first ICSI cycles between January 2006 and June 2013. In Group A (n=208), patients underwent a long luteal GnRH agonist protocol, and in Groups B (n=143) and C (n=59), patients underwent a GnRH antagonist protocol. The patients in Group C also received OCPs containing 30mg of ethinyl oestradiol and 3mg of drospirenone prior to treatment. The main outcome measures were pregnancy and ovarian hyperstimulation syndrome (OHSS) rates.Demographic features, body mass index, duration of infertility, serum baseline hormone levels, cycle outcomes, multiple pregnancy rates, miscarriage rates, OHSS rates, total number of Grade A embryos and total number of transferred embryos were comparable between the groups. Clinical pregnancy rates were 27.4%, 26.6% and 23.7% in Groups A, B and C, respectively (p=0.853).OCP pretreatment was found to have no beneficial or adverse effects in patients with PCOS undergoing a GnRH antagonist protocol for ICSI, but can be used for cycle scheduling.Copyright © 2014 Elsevier Ireland Ltd.
