Testosterone is the hormone responsible for the development of male sexual characteristics. It plays a crucial role in various physiological processes during puberty, including the growth of facial and body hair, deepening of the voice, and increase in muscle mass and strength. Additionally, testosterone is essential for the development of reproductive tissues such as the testes and prostate.

The hormone is primarily produced in the testes, but also in smaller amounts in the adrenal glands. Its effects are critical not only for physical development but also for driving libido and overall male health. The prominence of testosterone in defining male secondary sexual characteristics is well-established, differentiating male physiological traits from those associated with females, which are influenced primarily by hormones like oestrogen.
