Question
A fifth-grade student started to grow pubic hair around the age of 10 and frequently experiences erections. By the first grade of junior high school at age 12, hair began to grow under the armpits, followed by leg hair, which gradually extended upwards from the legs. Does this indicate signs of precocious puberty in the student?
Answer
Precocious puberty refers to the onset of secondary sexual characteristics before the age of sexual development, such as breast development, the appearance of pubic and armpit hair, rapid growth in height and weight, and the development of external genitalia. According to the definition, boys who start sexual development before age 10 can be diagnosed with precocious puberty. Therefore, if a student starts to grow pubic hair and other related signs around the age of 10, this may indicate the presence of precocious puberty. It is advisable to seek professional medical advice for diagnosis and appropriate treatment.
