What is Delayed Puberty?

Children reach puberty at different ages. Delayed puberty is when boys have little to no genital growth by age 14, or girls have no breast development by age 13, or no periods by age 16.

Delayed puberty may happen in children who have chronic medical conditions. Diet and family history can also affect normal growth and development. If either parent had late onset puberty, the chances are greater that their child may also have a late start to puberty.

What are the Symptoms of Delayed Puberty?

With delayed puberty, you might see the following in your child:

In boys age 14 and older:

Small testicles
No facial hair
Shorter than other boys their age

In girls:

Small or no breast development by the age of 13
Has not started their period by the age of 16
Shorter than other girls their age

For girls: estrogen and / or progesterone replacement therapy over a period of three to six months to jump-start their puberty

The provider will talk with you about any needed follow-up visits for your child.
