Precocious puberty generally occurs when secondary sexual characteristics appear relatively early. For example, girls may experience breast development, pubic hair, and underarm hair growth. Boys may experience enlargement of the testicles, growth of pubic hair, underarm hair, facial hair, deepening of the voice, and nocturnal emissions. If a child exhibits signs of precocious puberty, it can impact their growth and it’s important to promptly visit a hospital to check their sex hormones and bone age through X-rays. Treatment with medication can be initiated based on the specific circumstances of the child. If the child's bone age is normal, it is possible to suppress the secretion of the child's hormones.
