Question: 1 / 20

What hormone controls male traits, such as muscle growth and voice change?

Estrogen

Progesterone

Testosterone

Testosterone is the hormone that plays a crucial role in the development of male traits. It is predominantly produced in the testes and is responsible for a range of physiological changes during puberty in males. These changes include increased muscle mass and strength, deepening of the voice, growth of facial and body hair, and overall masculinization of body structure.

In addition to its physical effects, testosterone also influences sexual development and reproductive functions. Its role extends beyond just puberty, as it continues to influence various aspects of health and well-being throughout a man's life. The presence and levels of testosterone are key factors in distinguishing male secondary sexual characteristics, making it essential for understanding male biology and physiology.
