Objective To study whether intranasal GnRH agonist (GnRHa) can be effectively used for luteal support in high-responder patients undergoing fresh-embryo transfer after ovulation induction with the use of GnRHa. Design Retrospective cohort study. Setting Private fertility clinic. Patient(s) Forty-six high-responder patients were administered a GnRHa ovulation trigger to avoid ovarian hyperstimulation syndrome (OHSS), followed by 2 weeks of daily intranasal GnRHa (nafarelin) for luteal-phase support. No additional progesterone supplementation was administrated. Intervention(s) Intranasal GnRHa for luteal-phase support. Main Outcome Measure(s) The primary outcome was ongoing clinical pregnancy rate. Result(s) High median progesterone levels were measured at midluteal phase and on the day of the first positive pregnancy test (190 nmol/L on both measures). We obtained 24 (52.1%) ongoing clinical pregnancies. None of the patients developed OHSS. Conclusion(s) Intranasal GnRHa is effective in achieving luteal-phase support in high-responder patients triggered with GnRHa and avoiding OHSS.
