Changes in circulating hormone levels after ovarian wedge resection in patients with polycystic ovary syndrome

Serum gonadotropin, prolactin, estradiol, sex hormone binding globulin (SHBG) and androgen levels were measured before, 5 days and 6 weeks following ovarian wedge resection in 9 patients with polycystic ovary syndrome. Elevated levels of LH, androstenedione, testosterone and dehydroepiandrosterone-sulphate (DHEA-S) were found before surgery. There was a marked decrease in androstenedione and DHEA-S levels 5 days following wedge resection, but a rebound effect could be observed 6 weeks later. Serum gonadotropin, prolactin, testosterone and SHBG concentrations were practically unaffected by surgery. At 6–12 months follow up patients showed regular, mainly ovulatory cycles, but pregnancy occured only in two cases.
