[The effects of hormone replacement therapy on ovarian function in premenopausal women after hysterectomy].

OBJECTIVE: Examining the consequences of temporary postoperative hormone replacement therapy following hysterectomy for the function of the ovaries and the subjective well-being of women. MATERIAL AND METHODS: Hormone profiles (Estradiol, FSH, LH, Testosterone, DHEA) and typical estradiol deficiency phenomena were investigated prospectively in premenopausal hysterectomized women with intact ovaries. Group 1 (n = 21) was replaced transdermally following surgery for 3 weeks with estradiol patch 0.05 mg daily. Group 2 (n = 21) got no hormones. RESULTS: Group 1 had a remarkable decrease of estradiol after 10 days to 59% and after 6 weeks to 71% of the starting point. Gonadotropins showed an increase in this group. In group 2 without replacement there was only a small decrease of estradiol after 10 days and after 6 weeks the level was higher than before hysterectomy. Testosterone also decreased in group 1 to 64% of the level before surgery after 6 weeks, whereas in the comparing group it was 87%. On the other hand in group 1 only 2 of 21 women, but 10 of 21 in group 2 showed climacteric-like symptoms. CONCLUSIONS: HRT over 3 weeks induces ovarian suppression, which is still seen 6 weeks after hysterectomy. But hormonally treated women have clearly less subjective complaints.
