What changes will happen during puberty?Sexual and other physical maturation that happens during puberty is a result of hormonal changes. In boys, it is difficult to know exactly when puberty is coming. There are changes that happen, but they happen gradually and over a period of time, rather than as a single event. While each male adolescent is different, the following are average ages when puberty changes may happen:*.Beginning of puberty: 9.5 to 14 years old*.First pubertal change: enlargement of the testicles*.Penis enlargement: begins approximately 1 year after the testicles begin enlarging*.Appearance of pubic hair: 13.5 years old*.Nocturnal emissions (or "wet dreams"): 14 years old*.Hair under the arms and on the face, voice change, and acne: 15 years old
