Puberty: Adolescent Male
The teenage years are also called adolescence. During this time, an adolescent will see the greatest amount of growth in height and weight. Adolescence is a time for growth spurts and puberty changes.
An adolescent may expect to grow several inches in several months followed by a period of very slow growth, then will typically have another growth spurt. Changes with puberty may occur gradually or several signs may become visible at the same time.
There is a great amount of variation in the rate of changes that may occur. Some adolescents may experience these signs of maturity sooner or later than others. It is important to remember that these changes happen at different times for everyone. Being smaller or bigger than other males is normal as each child experiences puberty.
On average males begin puberty between 9½ to 14 years of age.
