Estrogen Effects on the Female Body
Estrogen is a group of hormones that play an important role in the normal sexual and reproductive development in women. They are also called sex hormones. The woman's ovaries produce most estrogen hormones, although the adrenal glands also produce small amounts of the hormones.
In addition to regulating the menstrual cycle, estrogen affects the reproductive tract, the urinary tract, the heart and blood vessels, bones, breasts, skin, hair, mucous membranes, pelvic muscles, and the brain. Secondary sexual characteristics, such as pubic and armpit hair also begin to grow when estrogen levels rise. Many organ systems, including the musculoskeletal and cardiovascular systems, and the brain are affected by estrogen.
