Objective : To describe the change of serum estradiol, follicul-stimulating hormone and testosterone after hysterectomy, and its difference according to the type of adnexal surgery in pre, and postmenopausal women. Materials and Method : Three hundred twenty four women presenting for hysterectomies for nononcologic reasons. We divide the women into four groups, who only hysterectomized, who with both adnexectomized, who with unilateral adnexectomized, and who with both salpingectomized. We collect the blood samples for serum estradiol and testosterone in preoperative day, 1 day after, 3 day after, 6 day after and 1 month after operation. And check FSH in a day before operation and 1month after operation. Result : Estradiol shows significant decrease in both adnectomy group compared to the unilateral adnexectomized and only hysterectomized. The both salpingectomized shows no difference with the both adnectomized. Testosterone shows no difference between groups in premenopausal women. In postmenopausal women, testosterone decreased 3 days after both adnexectomy compared to the only hysterectomized and the unilateral adnexectomized. The both salpingectomized shows no difference with the both adnexectomized. Conclusion : Testosterone decreases significantly in postmenopausal women after hysterectomy with both adnexectomy or both salpingectomy. So we think it was appropriate treatment to replace estrogen and testosterone in postmenopausal women who both adnexectomized or both salpingectomized.
