Research Overview
Leuprolide
Leuprolide is one of the best-studied GnRH analogs in reproductive medicine and assisted reproduction. It produces an initial flare followed by receptor desensitization and reduced LH/FSH output.
Cetrorelix
Cetrorelix is a cornerstone GnRH antagonist in assisted reproduction, with a fast onset and reversible suppression of LH. Trials show it improves cycle management by reducing premature ovulation during stimulation.
