The value of gonadotrophin and oestradiol concentrations following pituitary down-regulation with leuprolide acetate in predicting ovarian response to stimulation was evaluated in three groups of women undergoing ovarian stimulation for in-vitro fertilization with highly purified follicle stimulating hormone (FSH). Leuprolide acetate was started in the midluteal phase, and either stopped at menses (IVF-SL group, n = 3), or continued throughout stimulation (IVF-LL group, n = 38; oocyte donors, n = 58). Ovarian stimulation was started on cycle day 3, after blood was drawn for down-regulated FSH, luteinizing hormone (LH) and oestradiol. Higher down-regulated LH was predictive of higher oestradiol on day 5 of stimulation in both IVF groups, and of need for fewer ampoules in the IVF-LL group, but not of oestradiol on day of human chorionic gonadotrophin (HCG) administration or number of oocytes retrieved. Higher FSH after down-regulation predicted yield of fewer oocytes in the donor and IVF-LL groups, and higher oestradiol on day 5 of stimulation, need for fewer ampoules and a shorter duration of therapy in both IVF groups. Higher oestradiol after down-regulation was associated with higher oestradiol on day 5 of stimulation and on day of HCG administration, a shorter duration of therapy and need for fewer ampoules in all groups. Whereas these results do not ascribe any predictive significance to LH, they suggest that oestradiol and FSH concentrations after down-regulation are predictive of the pattern of ovarian response to stimulation and of oocyte yield.
