Doctor's answer:
In recent years, the average age of menarche among women has gradually been advancing, primarily due to improved nutritional conditions. The age of menarche varies from person to person, with a wide range. It can range from as early as 9 years old to as late as 18 years old; most people experience menarche between the ages of 12 and 14.
