- Description and Primary Use
- Estradiol is the most potent natural estrogen in humans. It regulates reproductive function in females and with progesterone, maintains pregnancy. Most estradiol is secreted by the ovaries (non-pregnant women) although the testes (in men) and adrenal cortex ( in men and women) secrete small amounts. During pregnancy, the placenta produces most of the circulating estradiol.
