title: Comparison of preovulatory follicular concentrations of epidermal growth factor, insulin-like growth factor-I, and inhibins A and B in women undergoing assisted conception treatment with gonadotropin-releasing hormone (GnRH) agonists and GnRH antagonists.
abstract: Follicular fluid contents of 69 age-matched women undergoing ovarian stimulation with a GnRH agonist and a GnRH antagonist were collected during oocyte retrieval. The groups did not differ in baseline characteristics and in terms of assisted conception treatment outcome. Similarly, follicular fluid levels of epidermal growth factor, insulin-like growth factor, and inhibins A and B were found not to be different. Our results suggest that follicular development in regard to ovarian growth factor dynamics is not different in women undergoing ovarian stimulation with GnRH antagonists than in women using GnRH agonists.
