| hormone replacement therapy | In females, treatment with sex hormones for a number for reasons, including menopause, partial or full hysterectomy, or amenorrhoea.In women, treatment with sex hormones is indicated for a number of reasons, including menopause, partial or full hysterectomy, or amenorrhoea. After menopause, conjugated oestrogens, estradiol, or estrone sulfate are given to reduce pain during intercourse, limit blood vessel effects, and prevent loss of bone mass. After radical hysterectomy, conjugated oestrogens are given for similar reasons. After menopause or partial hysterectomy, progestin is administered at the same time to offset an increased risk of endometrial cancer. In some amenorrhoeas, oestrogen is given to restore menses; if the therapy is unsuccessful, this may indicate the presence of pathology, for instance, pituitary tumour. Benefits for postmenopausal women include a lowered risk of heart attack (oestrogen lowers LDL and raises HDL levels), and prevention of osteoporosis, since the rate of bone loss is directly linked to a drop in oestrogen levels (see perimenopause). Medical opinion about the hazard posed by such therapy remains divided. Some studies have indicated increased incidence of breast cancer; however, a comprehensive 1992 review of the literature contradicted this finding. (05 Mar 2000) |
