Which hormone is produced in males and influences male characteristics?

• A. Testosterone
• B. Estrogen
• C. Progesterone
• D. Prolactin

Answer: (A)

Testosterone is the primary male sex hormone (an androgen) produced mainly by the testes. It drives the development of male characteristics such as facial and body hair, a deeper voice, greater muscle mass, and sperm production, especially during puberty and beyond. While small amounts of estrogen and progesterone exist in males, they do not drive these masculine traits. Prolactin has roles in lactation and certain reproductive processes but not in shaping male secondary sexual characteristics.
