Beneficial Effect of Luteal-phase Gonadotropin-releasing Hormone Agonist Administration on Implantation Rate Afterintracytoplasmic Sperm Injection

SummaryObjectiveTo evaluate the effect of gonadotropin-releasing hormone (GnRH) agonist, administered in the luteal phase, on intracytoplasmic sperm injection (ICSI) outcome.Materials and MethodsOne hundred and eighty women undergoing ovarian stimulation for ICSI were enrolled in this study. Patients were randomly assigned to receive a single dose of GnRH agonist or placebo. Implantation rate and clinical pregnancy rate were the main outcomes.ResultsAdministration of 0.1 mg of the GnRH agonist triptorelin on day 3 after embryo transfer led to a significant improvement in implantation rate (12.3% vs. 7.3%) and clinical pregnancy rate (25.5% vs. 10.0%) as compared with placebo.ConclusionLuteal phase GnRH agonist administration enhances ICSI clinical outcomes.
