This compound belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. Androstenediol used by the body to make testosterone and estrogen.

There is some concern that androstenediol might increase the risk of coronary heart disease. There is also developing evidence that androstenediol might help prostate cancer cells grow.

Androstenediol is a steroid. Androstenediol used to be available as a dietary supplement. But under the Anabolic Steroid Control Act of 2004, it was reclassified as a schedule III controlled substance. This means androstenediol is available only as a prescription medicine, and physicians have to follow strict rules when prescribing it. Androstenediol is used to increase the body's production of testosterone; increase energy; enhance recovery and growth from exercise; heighten sexual arousal and performance; and promote a greater sense of well-being.

The use of androstenediol has been banned by the National Collegiate Athletic Association (NCAA).

• A weak androgen and estrogen steroid hormone
• It is closely related to androstenedione
• Androstenediol is a direct metabolite of the most abundant steroid produced by the human adrenal cortex, DHEA.
• It has been found to stimulate the immune system.

When administered to rats, androstenediol, in vivo, has approximately 1.4% of the androgenicity of DHEA, 0.54% of the androgenicity of androstenedione, and 0.21% of the androgenicity of testosterone

Androstenediol possesses potent estrogenic activity
