How Do Doctors Evaluate Early Puberty in Boys?

Our evaluation of your son’s early puberty begins with a discussion about your son’s signs of puberty and a physical exam. If your son has signs of early puberty, we will typically have him get an X-ray of his left hand and wrist called a bone age. A bone age tells us how much your son’s bones have matured. It can also help us figure out if your son should have further evaluation with blood tests.

Your son might have a blood test to help us measure your child’s hormone levels. This will help us figure out if your son has gonadotropin dependent or independent puberty. It will also help us figure out if there is a concern about the adrenal glands. Depending on the results of the laboratory testing further radiology testing may include a head MRI.
