When do guys hit puberty

Your child has reached the stage of adolescence called puberty. In boys, puberty usually begins between the ages of 10 and Once it begins, it lasts about 2 to 5 years.

But every child is different. Typically, boys have their height spurt fairly late in puberty. Boys often have a lower percentage of body fat by the end of puberty.

At the start of puberty, the testicles increase in size, drop lower, and the scrotum darkens, becomes looser, and becomes dotted with small bumps. Later in puberty, the penis begins to grow and mature. Pubic hair begins to grow shortly after changes in the scrotum. At first it may be thin. It then gets darker and coarser. Boys also begin to grow hair in other new places, such as the chest, underarms, face, and legs about 2 years after the start of pubic hair growth.

Dark, coarse, curly hair will appear on her labia the folds of skin surrounding the vagina , and later, similar hair will begin growing under her arms. The first signs of puberty are followed 1 or 2 years later by a noticeable growth spurt. Her body will begin to build up fat, particularly in the breasts and around her hips and thighs, as she takes on the contours of a woman.

Her arms, legs, hands, and feet will also get bigger. The culminating event will be the arrival of menarche, her first period menstruation. Depending on the age at which they begin their pubertal development, girls may get their first period between the ages of 9 and The physical changes kids experience as they move toward adulthood often are accompanied by emotional consequences.

Some girls are excited about their budding breasts and new training bras; others may worry that all eyes are focused on their breasts. Some boys love the sight of themselves all lathered up with shaving cream; others may be uncomfortable with the attention they get for a few new shoots of hair. Pimples are common for most teens. Acne is caused by glands in the skin that produce a natural oil called sebum.

Puberty hormones make the glands produce extra sebum, which can clog the pores. Washing gently with water and mild soap can get rid of excess sebum and help reduce breakouts. Over-the-counter and prescription medications are available for more severe cases of acne.

Your family doctor can recommend a dermatologist a doctor who specializes in treating the skin if basic skin care and OTC medications don't keep acne under control. Kids who once associated bath time with play need to learn to wash regularly and to apply deodorant or antiperspirant. A teen who's learning to shave will need to learn how to keep a razor clean, to throw a disposable one away before it becomes dull and ineffective, and to not share it with others.

Your little boy is growing up and this also means that he may open up to you less often. It's common for teenage boys to become less talkative and withdraw from their parents. Keep the lines of communication open and talk to your son about the changes he's experiencing. Stay connected to his interests and talk to him about sports, school, or whatever he enjoys. This will help him feel comfortable about coming to you when he needs to talk about something important.

If your son hasn't started puberty by the age of 14, which means that his testicles and penis haven't started to grow yet, this is considered delayed puberty. The most common cause is called constitutional delayed puberty.

More than two-thirds of boys inherit this from one or both of their parents who also started puberty late. In girls, delayed puberty is starting menstruation after the age of 16 years.

The majority of boys who are constitutionally delayed are also short compared to other boys their age, but this is just because they haven't had their growth spurt yet. If your son has a chronic illness like sickle cell disease, inflammatory bowel disease, or cystic fibrosis, puberty may also begin later than normal.

A small number of boys have a condition called isolated gonadotropin deficiency IGD , which means that they don't produce adequate amounts of the hormones LH and FSH. This condition typically begins at birth and is typically treated with testosterone injections. An even smaller number of boys have something going on with their testicles that's causing puberty to be delayed. Testosterone is the main treatment for issues of this sort. If you have questions or concerns about how your son is progressing through puberty, talk to his healthcare provider.

Your doctor can determine if your teen is growing and developing as expected and help you understand the biology that's at work. In the case of suspected delayed puberty, it's possible that your son's penis and testicles have gradually started to enlarge and he just hasn't noticed. Your doctor can tell with a physical exam and can run some tests on your son's hormones to see if there are any problems.
