Early & Delayed Puberty
Puberty that starts too early — or arrives later than a child's friends — is one of the most common reasons families see a pediatric endocrinologist. Dr. Samuel Freedman evaluates puberty timing carefully and, when needed, treats it to protect a child's growth and well-being.
Early (precocious) puberty
Early puberty means the body starts maturing sooner than expected — generally before age 8 in girls and before age 9 in boys. In girls, the first sign is usually breast development; in boys, it's enlargement of the testicles, which is easy to miss. Other clues include pubic or underarm hair, a sudden growth spurt, adult body odor, acne, and in girls the early start of periods.
It's worth getting checked — not only because early changes can be hard for a young child socially and emotionally, but because early puberty can quietly shorten final adult height as the growth plates close ahead of schedule. When caught early, it is very treatable, often with a medication that gently pauses puberty until the right age.
Delayed puberty
Delayed puberty means the usual signs haven't appeared by the expected age. Many of these children are simply "late bloomers" (constitutional delay) — a normal variation that often runs in families and catches up with a later, longer growth spurt. We confirm that by checking growth velocity and bone age, and by ruling out other causes. When evaluation points to something treatable, there are safe, effective options.
How we evaluate & treat
Evaluation includes a history and exam, a look at the growth chart, and usually a bone-age X-ray and targeted labs. If treatment is appropriate, it works with your child's biology — for example, medication to pause early puberty simply presses the brakes until the right age, and development resumes normally when it's stopped. No treatment is right for every child, and any decision is made together, unhurried.
What are the first signs of early puberty?+
In girls, usually breast development before age 8; in boys, testicular enlargement before age 9. Other signs include pubic/underarm hair, a growth spurt, body odor, and acne.
Is medication to pause puberty safe?+
These medications are well-studied and FDA-approved for this use. They safely pause development until the appropriate age, and puberty resumes normally once stopped.
When should we worry about delayed puberty?+
If there are no signs of puberty by about age 13 in girls or 14 in boys, an evaluation is worthwhile — often it's a reassuring "late bloomer" pattern, but it's worth confirming.
