Estrogen

Estrogen is a hormone that plays various roles in the body. In females, it helps develop and maintain both the reproductive system and female characteristics, such as breasts and pubic hair.

The ovaries, adrenal glands, and fat tissues produce estrogen. Both female and male bodies have this hormone, but females create more of it.

In this article, we look at estrogen in more detail, including how it works, what happens when the levels fluctuate, and medical uses.
