What Is Estradiol?

Estradiol (E2), also known as oestradiol, is a major female sex hormone or estrogen hormone which plays an important role in the female reproductive system. It is used to regulate estrous and menstrual female reproductive cycles.

The hormone also plays a vital role in the development of female secondary sexual characteristics including widening of the hips, breasts, and a female-associated pattern of fat distribution.

It is also responsible for the development and maintenance of female reproductive tissues such as uterus, mammary glands, and vagina during adulthood, puberty and pregnancy. [Trusted Source]

It also has other important effects in many other tissues such as bone, liver, fat, skin and the brain.

However, in males the levels of estradiol are much lower as compared to those in females. But, it has important roles in men as well.
