Deepening of voice in boys during adolescence is mainly related to which hormone?

Answer and explanation

Correct answer: Testosterone

Testosterone, secreted mainly by the testes, is the principal male sex hormone responsible for many changes during male adolescence. It supports development of secondary sexual characteristics, including growth of the larynx and thickening or lengthening of the vocal cords, which makes the voice deeper. Estrogen is mainly associated with female reproductive changes, insulin regulates blood glucose, and auxin is a plant hormone. Therefore option B is correct.
