When do boys get body hair?

Boys typically begin to develop body hair during puberty, which usually starts between ages 9 and 14. The growth of body hair is driven by increased levels of hormones, particularly testosterone. Initially, boys may notice hair growth in areas such as the armpits and pubic region, followed by hair on the legs, arms, and chest as they continue to mature. The timing and extent of body hair development can vary significantly among individuals.
