Estrogen is the name of a group of hormones. There are three principle forms of estrogen found in the human body estrone (E1), estradiol (E2) and estriol (E3). There is also a group of compounds called phytoestrogens, generally found in food, which can have "estrogen like" effects in the body. Estradiol (E2) is the primary estrogen produced by the ovaries. Estrone (E1) is formed from estradiol. It is a weak estrogen and is the most abundant estrogen found in the body after menopause. Estriol (E3) is produced in large amounts during pregnancy and is a breakdown product of estradiol. Estriol is also a weak estrogen and may have anti-cancer effects. Before menopause estradiol is the predominant estrogen. After menopause estradiol levels drop more than estrone so that now estrone is the predominant estrogen.
