Patient's question:
NoDoctor's answer:
Generally speaking, the age range is from 11 to 15 years old. After 11, development accelerates rapidly, and then it gradually slows down after one to two years. Physical development, such as menarche and breast enlargement, occurs during this period. For girls who engage in sports, the development timeline may be delayed, with menarche typically occurring around the age of 16, though this is also quite normal.
