ObjectiveTo determine the incidence of premature luteinization in patients with polycystic ovary syndrome (PCOS) undergoing controlled ovarian hyperstimulation (COH) with exogenous gonadotropin/GnRH antagonist (GnRH-a); to compare clinical outcomes in patients with and without premature luteinization.DesignRetrospective case series.SettingIVF clinic.Patient(s)Thirty-five treatment cycles in 30 patients with PCOS.Intervention(s)Controlled ovarian hyperstimulation with gonadotropin/GnRH-a protocol.Main Outcome Measure(s)Premature luteinization defined as a P concentration of ≥1.3 ng/mL on the day of hCG administration; number of oocytes and two pronuclei (2PN) embryos; implantation and clinical pregnancy rates (PR).Result(s)The incidence of premature luteinization was 28%. Compared with those without premature luteinization, patients with premature luteinization had a higher number of oocytes retrieved (24.1 ± 13.3 vs. 12.0 ± 5.9) and greater number of mature oocytes (19.7 ± 11.7 vs. 9.5 ± 4.5), respectively. The number of good quality embryos and embryos transferred was not significantly different between groups. Although implantation rates (56% vs. 40%) and clinical PRs (36% vs. 30%) were higher in patients without premature luteinization, the differences were not statistically significant.Conclusion(s)The patients with PCOS with premature luteinization had a higher number of oocytes retrieved and mature oocytes, and similar clinical PRs as patients with PCOS without premature luteinization.
