Patient's question:
NoDoctor's answer:
It's possible for both boys and girls to start menstruation between the ages of 9 and 18. Most of them are between 13 and 15 years old. Nowadays, girls start menstruation earlier, with the earliest being at the age of 9, which may be due to improved living standards and better nutrition. Those who start a bit later might be influenced by family history or genetic factors. Some mothers start menstruation at 18, and their daughters also start around that age, which is perfectly normal.
