Precocious puberty

Precocious puberty is the early appearance of the signs of puberty. These signs show themselves at different times and in different ways in boys and girls.

Signs of puberty in boys are considered early if they appear before 9 years of age. They may include a growth spurt, voice changes, the appearance of underarm or pubic hair, and genital development. There's often no exact cause, and it may be caused by normal early hormone changes. Weight, some medical conditions, and genetics can also affect the timing of puberty. Diagnosis is based on medical history, a physical exam, and testing hormone levels in the blood. Treatment often depends on the boy's age when the changes develop and if a medical cause is found. Boys who develop signs of puberty very early may get treatment. This aims to slow down their development and help them grow to a normal height as adults. Many boys do not need treatment and will continue to develop normally.
