Testosterone is not unique to men. The ovaries in women produce both estrogen and testosterone. Relatively small amounts of testosterone are released into the bloodstream by the ovaries and adrenal glands. Estrogen and testosterone are sex hormones that play a role in the development of the gonads.

Estrogen is a female sex hormone, also known as female hormone. Estrogen plays an important role in women's health, beauty and physiology. If there is an estrogen deficiency, you may experience symptoms similar to menopause, such as hot flashes, insomnia and vaginal dryness.
