Which hormone helps develop secondary sexual characters in boys during adolescence?
Answer and explanation
Correct answer: Testosterone
The governing concept is hormonal regulation of puberty. During adolescence, the testes produce increasing amounts of testosterone. This hormone contributes to secondary sexual characteristics in boys, including a deeper voice, facial and body hair, increased muscle development, and maturation of the reproductive system. Thus option A is correct. Estrogen is principally associated with female reproductive development, while insulin and thyroxine have different metabolic roles.
