Estrogen

An important group of hormones essential for normal women’s maturation and the healthy functioning of reproductive and other tissues. During the reproductive years in women estrogens are primarily made in the ovaries. Estrogen is also normally made in children, men and menopausal women by conversion of androgens in fat and muscle tissues. There are three kinds of estrogens. Estradiol is the ovarian hormone of the premenopausal years, estrone is the hormone of the menopausal years and estriol, a weak estrogen is present in high levels during pregnancy. High levels are associated with nausea, breast tenderness, insulin resistance and fluid retention. OR the name for a family of hormones including estradiol, estrone and estriol.
