Estrogen is the primary female sex hormone. Among other roles, it promotes the development and maintenance of female characteristics in the human body. Estrogen is a generic term for estrus-producing compounds; the three most common naturally occurring estrogens are: Estrone (E1), estradiol (E2), and estriol (E3).
Within the past 40 years, they predicted the presence of neural estrogens, but they did not know whether the brain could actually make and release estrogen. Most estrogens, such as estradiol, a primary hormone that controls the menstrual cycle, are produced in the ovaries. Estradiol circulates throughout the body, including the brain and pituitary gland, and influences reproduction, body weight, and learning and memory.
