Testosterone is the primary male sex hormone that is responsible for the development and maintenance of male physical characteristics. Testosterone plays a key role in several bodily functions in men, including:
Bone and muscle growth. Testosterone stimulates bone mineralization and growth, allowing men to build more muscle mass and have greater bone density than women. This is why men tend to be taller and have more muscle than women on average.
Sperm production. The testes rely on testosterone to produce spermatozoa for reproduction. Men need adequate testosterone levels to produce healthy sperm counts.
Sex drive. Testosterone is a key hormone that regulates libido and sexual function in men. Lower testosterone levels can lead to a reduced sex drive.
Facial and body hair growth. Under the influence of testosterone, boys undergo growth of darker, coarser body and facial hair during puberty. Testosterone determines male hair patterns like beards.
Voice deepening. Rising testosterone production during puberty causes the larynx and vocal cords to grow, leading to the characteristically deeper voice tone in men.
So in summary, testosterone plays a vital role in male physical development and several key bodily processes. Deficiencies in testosterone can lead to delayed or impaired puberty, reduced muscle mass, low energy levels, infertility, loss of sex drive, and other effects.
