What is esterified estrogens and methyltestosterone, and how does it work (mechanism of action)?
Esterified estrogens are a mixture of related estrogens. Estrogens, when taken alone or in combination with a progestin, have been shown to reduce the risk for hip fracture due to osteoporosis by 25% as well as the risk of heart attack (myocardial infarction) and stroke by 40-50%. Esterified estrogens are used for numerous medical situations. Estrogens cause growth and development of female sex organs and the maintain sex characteristics, including growth of underarm and pubic hair and shaping of body contours and skeleton. Estrogens also increase secretions from the cervix and growth of the inner lining of the uterus (endometrium). Estrogens reduce LDL-cholesterol ("bad" cholesterol) and increase HDL-cholesterol ("good" cholesterol) concentrations.
Testosterone is the major male sex hormone that is responsible for many male sexual characteristics, but women also produce small amounts of testosterone. Following menopause, a woman's production of testosterone decreases. When testosterone in the form of methyltestosterone is added to estrogens, there may be a further alleviation of the hot flashes seen after menopause, and there also may be an improvement in a woman's sexual function.
