Question

Which hormone is primarily responsible for sexual and physical changes in boys during puberty?

Options

• Insulin

• Adrenaline

• Testosterone

• Oestrogen

Answer 1

Testosterone is the primary hormone responsible for sexual and physical changes in boys during puberty. This hormone drives the development of male secondary sexual characteristics, including increased muscle mass, deeper voice, facial and body hair growth, and skeletal development. Testosterone is produced in the testes and becomes significantly elevated during adolescence, triggering the cascade of physical changes associated with male puberty.
