To evaluate the suppression and flare regimens of gonadotropin-releasing hormone agonist (GnRH-a) in ovarian hyperstimulation in women with variable basal gonadotropin values in an in vitro fertilization (IVF) program.A retrospective study comparing the initiation of GnRH-a in the midluteal phase of the preceding cycle (suppression protocol) and follicular phase of the stimulated cycle (flare protocol) in women with basal follicle-stimulating hormone (FSH) values15 mIU/mL andor = 15 mIU/mL.The pregnancy rate per initiated cycle and implantation rate for women with basal FSH levelsor = 15 mIU/mL were 20.4% and 9.8% in flare GnRH-a cycles and 11.7% and 3.5%, respectively, in suppression GnRH-a cycles. Comparing the percent differences in clinical pregnancy and implantation rates between both protocols for women with different basal FSH values, pregnancy outcome was significantly greater in the flare protocols in women with valuesor = 15 mIU/mL (P.001). Individualization of the stimulation protocol by retrospective sorting of women undergoing IVF with respect to their basal gonadotropin levels significantly improved clinical pregnancy (P.05) and implantation rates (P.05) and reduced the cancellation rate (P.05).The flare regimen with GnRH-a is a useful alternative for controlled ovarian hyperstimulation in women with elevated basal FSH values (or = 15 mIU/mL) undergoing IVF. |
