Estrogens or oestrogens (from Greek οἶστρος (oistros), lit. “gadfly”) are a group of female sex hormones that are produced primarily by the ovaries. A woman’s body produces estrogen from two to ten times more than man’s. Estrogen lays the foundation for femininity and affects all organs and tissues. It causes the evolving of a feminine physique, behavior and character. Estrogen regulates the menstrual cycle, protects arteries against calcification and bone thinning and helps to maintain balance in blood. It also causes the thickening of the lining of the uterus after menstruation. During pregnancy, estrogen promotes the growth of breast and uterus and stimulates the beginning of the birth.
