Background: Many research works showed that menstruation is caused by the sudden reduction of the estrogens and progesterone to low levels of secretion at the end of the menstrual cycle. However, it should be investigated to which levels the concentration of these two hormones sharply reduces to cause menstruation. Objective: To determine estradiol concentration at the beginning of menstruation, the second day of menstruation and the ending of menstruation during the menstrual cycle. Subject and methods: 30 women with the normal menstrual cycle and 30 women with the long menstrual cycle were used as subjects to determine estradiol concentration at the day at the beginning of menstruation, the second day of menstruation and the last day of menstruation during the menstrual cycle. Result and Conclusion: In the women group with the normal menstrual cycle, the estradiol concentration: at the day at the beginning of menstruation is 159.93 \xb1 51.29 pmol/L, at the second day of menstruation is 170.58 \xb1 46.54 pmol/L and at the lastday of menstruation is 177.55 \xb1 46.42 pmol/L. In women in the group with long menstrual cycle, the estradiol concentration: at the day of beginning of menstruation is 154.55 \xb1 61.60 pmol/L and at the last day of menstruation is 154.55 \xb1 61.60 pmol/L.

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.
