The average age of onset is 12 to 14 years old. It is generally believed that in people with a high standard of living, good nutrition and good health, girls not only grow faster in size, but also have their first menstruation earlier. Some have more opportunities to come into contact with sexual knowledge, and through the regulation of the endocrine glands by the nervous system, the sex-related endocrine system becomes active prematurely, thus bringing forward the onset of menarche. Some girls may have delayed menstruation due to reasons such as poor health, malnutrition or obesity, living in a poor geographical environment, cold climate, etc., which are not conducive to puberty development and cause late menarche.
