Secretion of estrogen by the ovaries in response to pituitary hormones. Over an interval of about 2 to 3 years, estrogen stimulates growth of the uterus (as well as height growth, breast growth, widening of the pelvis, and increased regional adipose tissue). Estrogen stimulates growth and vascularity of the endometrium, the lining of the uterus.
Puberty blockers (also called puberty inhibitors or hormone blockers) are medicines used to postpone puberty in children. The most commonly used puberty blockers are gonadotropin-releasing hormone (GnRH) agonists, which suppress the natural production of sex hormones, such as androgens (e.g. testosterone) and estrogens (e.g. estradiol).
