OBJECTIVE: To examine the effects of growth hormone (GH) on ovarian responses to exogenous gonadotropins after pituitary desensitization in normal and poor responder patients undergoing in vitro fertilization. DESIGN: A prospective study with comparison of control and GH-treated cycles. PATIENTS: Poor responder patients (n = 10) required > 44 ampules of human menopausal gonadotropin (hMG) to achieve criteria for administration of human chorionic gonadotropin (hCG) on day 0 or cancellation in control cycles, and normal responder patients (n = 10) required < 45 ampules. MAIN OUTCOME MEASURES: Ovarian responses to hMG assessed by duration of stimulation required to achieve first significant estradiol (E2) response and hCG criteria. Total doses and duration of hMG, follicular development and E2 concentrations on day 0, and embryology were also assessed. RESULTS: Growth hormone showed no effect on any of the parameters studied in either patient group. CONCLUSION: Follicular recruitment, E2 secretion by mature follicles, and oocyte yield and quality were uninfluenced by GH treatment.
