Abstract

PIP: Various aspects of climacteric treatment with natural human estrogens are discussed. Estradiol, estradiol valerate, estron sulfate, or estriol are used separately or together in various preparations to treat the symptoms of approaching menopause. Estrogen treatment causes proliferation of the endometrium and causes a decrease in LHRH, FSH, and LH secretion. Treatment can take the form of continuous or cyclic treatment with estrogens alone, or sequential estrogne/gestagen preparations can be used. Ovarian function decreases as menopause approaches and results in the cessation of ovulation. Then the hypolutein phase begins, during which the secretion of progesterone is reduced and menstrual bleeding irregularities begin to occur. Eventually, estrogen production decreases so much that menstruation ceases completely, and symptoms such as heat flashes are experienced. Women who want treatment for climacteric symptoms but who want no regular menstrual bleeding can be administered low doses of pure estrogen. Regular abrasio control of endometrial development should be performed, however. Pure estrogen treatment can also be used in the case of hysterectomized women. Otherwise, a sequential treatment is generally indicated. Possible side effects of estrogen substitution therapy are changes in the genitalia, breasts, menstrual bleeding, blood pressure, and weight. There is also an indication that estrogen use can induce endometrial cancer. Besides the definite contraindication of endometrial cancer, relative contraindications of estrogen therapy include breast cancer, reduced liver function, thromboembolic disease, and serious hypertension. Estrogen therapy is to be used to solve acute climacteric symptoms; women should be well informed about possible side effects and that the therapy is no panacea for all menopausal problems.
