    Summary · context
    The efficacy and safety of the GnRH antagonist ganirelix was assessed in a multicenter, controlled, open-label study, in which Chinese women were randomized to either ganirelix (n = 113) or a long GnRH agonist protocol of triptorelin (n = 120).
    Summary · context
    The primary end point was the amount of recombinant follicle-stimulating hormone (rFSH) required to meet the human chorionic gonadotropin criterion (three follicles ≥17 mm).
