hormones, the same as in girls
Boys do not experience a menstrual cycle like girls do because they do not have a uterus or the hormonal processes associated with menstruation. Instead, boys undergo puberty, which involves changes such as increased testosterone levels, growth of facial and body hair, and voice deepening. While they don't have periods, boys may experience other bodily changes and hormonal fluctuations during adolescence.
Testosterone is the main hormone causing changes in boys during puberty. It is responsible for developing masculine characteristics such as facial and body hair growth, deepening of the voice, and muscle development.
