Doctor's answer:
Estrogen is a female hormone produced by the ovaries and placenta. The adrenal cortex also produces a small amount of estrogen. After girls enter puberty, the ovaries begin to secrete estrogen to promote the development of the vagina, uterus, fallopian tubes, and ovaries themselves, while the endometrium thickens to produce menstruation.
