Estrogen is secreted by the ovaries and adrenal glands. There are three types of estrogen found in a woman's body: estrone, estradiol and estriol. Estrogen Replacement Therapy (ERT) has turned out to be a lifesaver for millions of postmenopausal women who benefit from its use. A survey examining the benefits of ERT on women found that overall mortality from all causes was reduced. In particular, deaths due to coronary artery disease and stroke were reduced.
