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).
Estrogen is a hormone used to relieve the symptoms of menopause. A woman whose uterus has been removed can use estrogen only (E). But a woman who still has a uterus must add progesterone or a progestin (synthetic progesterone) along with the estrogen (E+P).
