Though traditionally thought of as a male hormone, women also produce testosterone but in much smaller amounts.
In men, its levels increase during puberty to promote the development of male sex traits, such as body hair growth, a deeper voice, sex drive, and increased height and muscle mass. They affect various parts of your body, such as your muscles, hair follicles, bones, liver, kidneys, and reproductive and nervous systems. Anabolic-androgenic steroids (AAS) are a synthetic form of testosterone, which is the primary male sex hormone ( 1).
