Testosterone is the principal male sex hormone and an anabolic steroid. In men, testosterone plays a key role in the development of male reproductive tissues such as sex organs, muscle growth and the prostate. Testosterone is also responsible for sex drive and energy levels as well as promoting secondary sexual characteristics such as facial hair and deepening of the voice.

Females are more sensitive to the testosterone hormone which supports female sexual desire and the maintenance of healthy bones and muscles. On average, an adult male produces about ten times more testosterone than an adult female. While testosterone is essential for good health and well-being, the role of Testosterone in both men and women’s bodies goes beyond sex drive and muscles.
