1 Boys enter puberty about one year later than girls. 2  The first sign is enlargeÂ­ment of the testes and a thinning and reddening of the scrotum, which hapÂ­pens at an average age of eleven but may occur anytime between nine to fourteen years. For boys, the peak growth period occurs about two years after the beginning of puberty. 2  If a boy shows no signs of puberty by age 14, consult with your pediatrician. 3  See Physical Development in Boys: What to Expect.
