The Effect of Androgen Blockade on Granulosa Cell Estradiol Production after Follicle-Stimulating Hormone Stimulation in Women with Polycystic Ovary Syndrome
2006
Context: Previously, we have shown that women with polycystic ovary syndrome (PCOS) exhibit an exaggerated serum estradiol (E2) response to recombinant human FSH (rhFSH) (150 IU) compared with similarly treated normal women. This enhanced granulosa cell responsiveness is consistent with excessive follicular development after gonadotropin therapy and the corresponding risk of ovarian hyperstimulation syndrome. In vitro studies have shown that granulosa cells treated with androgens display greater FSH-induced E2 production than untreated cells, suggesting a role for androgens in granulosa cell responsiveness. Main Objective: This study was conducted to determine whether blockade of androgen action in PCOS women by administration of the antiandrogen flutamide would alter E2 responses to rhFSH. Design: We conducted a prospective cohort study. Subjects and Setting: We studied 11 women with PCOS at an institutional general clinical research center. Intervention: On study d 1, each subject received 150 IU rhFSH ...
