Precocious puberty is primarily characterized by the development of breasts in girls before the age of 8, which leads to a diagnosis of precocious puberty. In boys, an increase in testicular volume and thickening of the penis before the age of 9 or 9.5 years also constitutes a diagnosis of precocious puberty. Once children show signs of precocious puberty, it is crucial to promptly take them to a hospital for the following relevant examinations to determine whether the condition is affecting the child's physical and psychological health. 1. An examination of bone age to determine if it impacts the child's height; 2. An ultrasound of the gonads to verify the severity of sexual development; 3. Under the detailed examination of a doctor, observe whether it affects the child's psychology, thereby providing further reasonable treatment based on the actual manifestations of the child.
