Abstract:
A comparative study of four treatment regimens for women with a history of poor response to controlled ovarian hyperstimulation (COH) during attempts at in vitro fertilization (IVF) and embryo transfer suggested the feasibility of pretreatment with oral contraceptives (OCs). The 60 women enrolled in the study exhibited one or more of the following in an initial stimulated IVF cycle: three or fewer dominant follicles recruited, serum estradiol levels of 300 pg/ml or below, and/or a spontaneous luteinizing hormone (LH) surge prior to oocyte retrieval. Study subjects were assigned to one of four protocols: Group I--OCs for 3 weeks followed by COH; Group II--luteal phase leuprolide acetate with subsequent COH; Group III--short-flare Lupron with subsequent COH; and Group IV--COH alone. COH consisted of 150 IU/day of pure follicle-stimulating hormone (pFSH) and 150 IU/day of human menopausal gonadotropin (hMG). The mean age of women in each group ranged from 36.0 to 38.8 years. There were no significant differences among groups in terms of number of days of stimulation, total ampoules of hMG and pFSH required, peak serum estradiol and progesterone, number of oocytes retrieved and fertilized, and embryos transferred. However, the pregnancy rate was significantly higher (p < 0.05) in Group I (9/30, 30%) than in Group II (2/32, 6%), Group III (0/11, 0%), and Group IV (0/10, 0%). The good outcome associated with OC pretreatment may reflect production or alterations of local ovarian growth factors and/or changes in endometrial expression. Administration of exogenous estrogen may be particularly beneficial for perimenopausal women in their forties with ovarian follicular depletion.
