To compare the clinical characteristics in a Utrogestan and hMG protocol with the use of different doses of Utrogestan in normally ovulating women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatments.DesignProspective controlled study.SettingTertiary-care academic medical center.Patient(s)A total of 150 infertile patients undergoing IVF/ICSI treatments.Intervention(s)Utrogestan and hMG were administered simultaneously beginning on cycle day 3. The dose of Utrogestan was 100 mg/d in the study group and 200 mg/d in the control group. When the dominant follicles reached mature, 0.1 mg GnRH agonist was used for trigger. Viable embryos were cryopreserved in both protocols for later transfer.Main Outcome Measure(s)The primary outcome measure was the incidence of premature LH surge. Secondary outcomes included the embryo results and clinical pregnancy outcomes.Result(s)Consistent LH suppression was achieved during controlled ovarian hyperstimulation with Utrogestan at 100 mg, and the number of patients with profound LH suppression (LH <1.2 IU/L) in the low-dose group was significantly less than that in the high-dose group. The number of oocytes retrieved in the low-dose group was similar to that in the high-dose group (9.87 ± 5.77 vs. 10.25 ± 5.43). No significant differences were observed in the number of mature oocytes, viable embryos, clinical pregnancy rate, or implantation rate.Conclusion(s)Utrogestan at 100 mg is as effective as Utrogestan at 200 mg in reducing premature LH surge during controlled ovarian hyperstimulation.Clinical Trial Registration NumberChiCTR-OOC-14005277.
