Patient's question:
A 6.5-year-old boy has recently grown some mustache hair, which is a bit dark but not particularly heavy. Is this precocious puberty or normal?Doctor's answer:
Hello, according to the diagnostic standards in our country, the appearance of secondary sexual characteristics in boys before the age of nine is considered precocious puberty. However, this alone does not indicate the presence of secondary sexual characteristics. It is recommended to take the child to the hospital for a check-up, and if necessary, have their bone age and hormone levels checked. Precocious puberty refers to the appearance of secondary sexual characteristics in boys before the age of nine, characterized by an enlarged testicular volume, increased penis thickness and length, the appearance of axillary and pubic hair, a lower voice, and a masculine body type with facial hair. If the child has started growing facial hair, it is recommended to visit the growth and development department promptly.
