Prevalence of an endogenous LH rise following final GnRH antagonist dose in the IVF antagonist protocol [PDF]
European Journal of Obstetrics & Gynecology and Reproductive Biology: XBackground: The GnRH antagonist protocol is widely used in IVF/ICSI treatments. It involves daily injections of a GnRH antagonist starting on stimulation day 5 or later to prevent premature ovulation by suppressing the endogenous gonadotropin surge ...
