Testosterone is the hormone responsible for the development of male sexual characteristics. Hormones are chemical messengers that trigger necessary changes in the body. Females also produce testosterone, usually in smaller amounts. It is a type of androgen produced primarily by the testicles in cells called the Leydig cells.
