Effect of duration of gonadotropin releasing hormone agonist on the outcome of in vitro fertilization-embryo transfer in a short-acting long regimen.

ABSTRACT: Objective: To investigate the effect of the duration of gonadotropin releasing hormone agonist (GnRH-a) use on the outcome of in vitro fertilization and embryo transfer (IVF-ET) during the short-acting long-term hyperstimulation cycle. Methodology: Clinical data from 776 patients receiving controlled ovarian stimulation (COS) after short-term regimen downregulation were retrospectively analyzed. According to the duration of GnRH-a, the patients were divided into 3 groups: Group A, 14 days for GnRH-a; Group B, 15-17 days for GnRH-a; and Group C, >18 days for GnRH-a. The clinical data, treatment and clinical outcomes were compared among the groups. Results: There were no significant differences in fertilization rate, implantation rate, clinical pregnancy rate, abortion r
