title: Effect of estrogen/progestin administration on the ovarian response to gonadotropins: a randomized, prospective study.
abstract: The findings of our study indicate that women pretreated with E/progestin demonstrate increased gonadotropin requirements when undergoing ovulation induction. Whether this treatment has a significant effect on the outcome of ovulation induction in patients receiving gonadotropins remains to be established.
