What is Testosterone?
Known as an androgen (male sex hormone), testosterone is responsible for several things affecting both the male and female body. For males however, testosterone controls the development of their primary and secondary sex characteristics, such as development of penis, sperm, sex drive, deeper voice, and hair growth. Insufficient testosterone levels – due to age, disease, physical abnormalities, or drugs – has generally been known to cause such problems as decreased libido and interference with the development of sexual organs. Therefore, testosterone level is often higher for young adults naturally.
