Estradiol is a form of the hormone estrogen, and it’s also called “17 beta-estradiol.” The ovaries, breasts, and adrenal glands make estradiol. Estradiol helps with the growth and development of female sex organs, including the: uterus, fallopian tubes, vagina and breasts.

Estradiol helps to control the way fat is distributed in the female body. It’s also essential for bone and joint health in females. Testing can be recommended if a women is having abnormal menstrual cycle, abnormal vaginal bleeding and infertility.

High levels of estradiol could indicate an ovarian tumor or hyperthyroidism. If your estradiol levels are low, it can indicate polycystic ovary syndrome (PCOS) or hypopituitarism. Women with eating disorders or extreme endurance exercising may have low levels of estradiol.

Males also have estradiol in their bodies. Their levels of estradiol are lower than the levels in females. In males, the adrenal glands and testes make estradiol.
