Back to Sexual health. Puberty is the process of growing from a boy into a young man. Here's what to expect. If puberty hasn't started yet, don't worry.
Enlargement of the Testicles and Scrotum
The teenage years are also called adolescence. During this time, the teenager will see the greatest amount of growth in height and weight. Adolescence is a time for growth spurts and puberty changes. An adolescent may grow several inches in several months followed by a period of very slow growth, then have another growth spurt. Changes with puberty may happen 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 happen. 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 boys is normal as each child experiences puberty at his own time.
Puberty — it's a crazy time and occurs through a long process, beginning with a surge in hormone production, which in turn causes a number of physical changes. Every person's individual timetable for puberty is different. Below is an overview of some physical changes boys can expect during these years. A near doubling in the size of the testicles and the scrotal sac announces the advent of puberty. As the testicles continue to grow, the skin of the scrotum darkens, enlarges, thins, hangs down from the body and becomes dotted with tiny bumps. These are hair follicles. In most boys, one testicle usually the left hangs lower than the other. Fueled by testosterone, the next changes of puberty come in quick succession. A few light-colored downy hairs materialize at the base of the penis.
