Description: Estrone, also known as E1, may be measured in women who have gone through menopause to determine their estrogen levels. It also may be measured in men or women who might have cancer of the ovaries, testicles, or adrenal glands. Estrone is naturally produced by the ovaries in women and the fat tissue linings in children, men, and postmenopausal women.
