What gland produces estrogen?

The adrenal gland produces estrogen. A typical human being has two adrenal glands, with one gland located above each kidney. The gland is triangular and typically measures 1.5 inches vertically and 3 inches horizontally.

The adrenal gland is made up of two parts. The outside of the gland is called the adrenal cortex, and the inside of the gland is the adrenal medulla. Estrogen is released by the gland through the adrenal cortex. The gland produces less estrogen than other estrogen-producing organs, such as the ovaries or testes. An adrenal gland that produces too much or too little estrogen can cause health problems in men and women. The adrenal gland also produces the hormone cortisol.
