PURPOSE: Women undergoing in vitro fertilization with low ovarian reserve and poor response to controlled ovarian hyperstimulation (COH) present a management dilemma. In a retrospective observational study, we compared the pretreatment use of the gestogen medroxyprogesterone acetate (10 mg twice daily from day 15 of the cycle for a minimum of 2 weeks) with an oral contraceptive pill (one tablet daily from day 4 of the cycle for a minimum of 3 weeks). METHODS: The criteria for inclusion in the study included one or more of the following: abandoned cycles due to poor response, fewer than four oocytes retrieved following a standard COH protocol, age > 39 years, and elevated basal serum follicle-stimulating hormone (FSH). Thirty-eight women received pretreatment with gestogen, and a similar number of women received pretreatment with the pill. The flare protocol was used in all treatment cycles combined with an individualized dose of human menopausal gonadotropin (hMG) (4-8 ampoules/day of 75 units FSH/ampoule) depending on previous response, age, and early follicular serum FSH level. Both groups were similar in mean age, duration of infertility, early follicular FSH levels, and the distribution of various aetiologies. RESULTS: Twenty-nine cycles were abandoned before oocyte retrieval, 15 (39.5%) in the pill group and 14 (36.8%) in the gestogen group, because of an inadequate ovarian response. The mean (+/- SD) number of ampoules (75 IU FSH/ampoule) of hMG used per cycle was similar in the pill and gestogen groups (59.7 +/- 19.3 vs. 70.2 +/- 29.4, respectively). There also was no difference seen in the numbers of oocytes retrieved (4.4 +/- 2.3 vs. 4.2 +/- 2.5), total number of embryos (2.5 +/- 2.4 vs. 2.2 +/- 1.1), or the number of embryos transferred (1.8 +/- 1.2 vs. 2.1 +/- 1.0) in the pill and gestogen groups, respectively. One pregnancy in each group resulted following embryo transfer in 22 women in the pill group and in 24 women in the gestogen group. CONCLUSIONS: We conclude that pre-IVF treatment with oral contraceptive pill or gestogen combined with the flare protocol in women at high risk of or with a history of poor ovarian response, as defined in this study, did not appear to result in an improvement in outcome of IVF-embryo transfer.
