title: The induction of ovulation with pulsatile gonadotrophin-releasing hormone (GnRH) administration in hyperandrogenic women after down-regulation with buserelin or suppression with an oral contraceptive.
abstract: The hypothalamic-pituitary axis of 22 hyperandrogenic infertile women had suppression with either the gonadotrophin-releasing hormone (GnRH)-analogue buserelin (n = 12) or with an oestrogen-gestagen compound (Diane; n = 12). This was followed by pulsatile GnRH application for inducing ovulation (Zyklomat). In terms of ovulation and pregnancy rates the buserelin pre-treatment was more effective than the steroid pre-treatment, especially in hyperandrogenic non-polycystic ovaries (PCO).
