Answer 1

At the time of puberty, the hormone that triggers changes is testosterone.

Explanation:

At the time of puberty, testosterone is the hormone that triggers changes in boys, leading to the development of secondary sexual characteristics such as deepening of the voice, growth of facial and pubic hair, and increase in muscle mass. In girls, estrogen plays this role. Testosterone is the principal hormone responsible for initiating male puberty changes.
