Teenage puberty is a necessary stage in a teen's development. This is the time that your teen's body gets ready for reproduction. But it can be confusing and even frustrating! So many things are changing for your teen right now. So how do you know what is okay and what isn't?

Everyone goes through some of the physical changes of puberty. These changes usually occur in predictable stages.

Stages of Puberty in Girls

Girls go through five stages of breast development, usually from ages 8 to 15. Pubic hair development is another sign of puberty, emerging from age 9, with five different stages.

General signs include hips getting fuller and waist getting thinner. Along with pubic hair, they will also develop underarm hair and leg hair, along with the need for deodorant.

Stages of Puberty in Boys

Puberty usually starts around age 13 and progresses through five stages of sexual maturity. Testicles and penis enlarge, and pubic hair develops. Underarm hair and body hair will grow, and facial hair is another big change for boys.

As puberty hormones kick in, they will grow in height, shoulders will broaden, and they'll have more muscle. Their voice will also begin to deepen, often with cracking at first. They'll be perspiring more and need deodorant or antiperspirant. Sexual feelings and wet dreams will become more common.

Menstruation

Sometimes knowing the general stages isn't enough. For girls, what is normal for one teen isn't normal for another. Teen girls also have one more issue in puberty that boys don't: menstruation.

Getting their first period can fill girls with questions and even fear. While the average age of the first period is 12, parents need to be ready for it to happen as soon as age 8. Prepare by knowing what is normal, understanding what is happening during the menstrual cycle, and what to discuss with your doctor.

Penis Changes

For some teens, concerns about puberty deal with how the penis changes. Although they are sometimes embarrassed to ask their questions, many teens have concerns about if they are normal or not.

  • Puberty and Penis Size: While you may keep repeating that size doesn't matter, your child is probably still wondering what's typical.
  • How to Care for an Uncircumcised Penis: With puberty, there may be some conditions of the foreskin you want to watch for and report to your doctor. It's also time to ensure your teen knows how to properly clean their genitals to prevent problems.

A Word From Verywell

If you have any questions about how your teen is going through puberty, your pediatrician or family healthcare provider can provide you with information specific to your teen. Then, with some information (and a sense of humor), you and your teen will make it through puberty together!
