Which hormone is primarily responsible for changes in males during puberty?
Show answer & explanation
Correct answer: C
Explanation
Correct Answer:
Testosterone
Explanation:
Testosterone is the primary male sex hormone responsible for regulating the development of male secondary sexual characteristics during puberty. Produced mainly by the testes, it triggers physical changes such as deepening of the voice, growth of facial and body hair, increased muscle mass, bone development, and the maturation of reproductive organs.
Key Points:
While testosterone is the primary male hormone, small amounts are also produced in females by the ovaries. Conversely, oestrogen is the primary female sex hormone responsible for female pubertal development.
