- Estrone, also called E1, is the main female hormone made by women after menopause. Menopause is a time in a woman’s life when her menstrual periods have stopped and she can’t become pregnant anymore. It usually starts when a woman is around 50 years old.
- Estradiol, also called E2, is the main female hormone made by nonpregnant women.
- Estriol, also called E3 is a hormone that increases during pregnancy.
