Full Answer

Young males typically begin puberty between the ages of 9 and 16, and it can last anywhere from two to five years. The age of onset is not a reliable indicator of the duration of puberty or a person's final height, which depends on when the epiphyseal growth plates close. This usually occurs near the end of puberty. At this point, the bones stop lengthening and men reach their full height.
