A sex hormone, found naturally in a woman's body, that is produced by the ovaries, adrenal glands and other tissues. Androgen plays a key role in regulating certain bodily functions, including the growth spurt at puberty. It is believed to regulate the function of many organs, including the reproductive tract, kidneys, liver and muscles. Androgen levels begin to drop in a woman's twenties. By the time she reaches menopause, they are half of what they were in her early 20s. This can result in, among other things, a decreased sex drive. Androgen also can promote male characteristics, such as hair formation and a deepening voice.
