Many parents are concerned about their children's precocious puberty, but there are strict medical definitions. Girls develop breasts before the age of 8, menarche before the age of 10, and boys develop secondary sexual characteristics before the age of 9, which is considered precocious puberty.

Firstly, under normal circumstances, the approximate adolescent development schedule for both men and women. The earliest sign of puberty in girls is breast development, which usually occurs between the ages of 8-10 and up to 13. Then, pubic hair grows and vaginal secretions increase, usually between 9-11 years old. Finally, menarche occurs, with an average age of around 12 years old. Girls stop growing in height around the age of 15-17. The initial manifestation of adolescent puberty is testicular enlargement, usually 10-12 years old, with the latest being 14 years old. Then, scrotal development, pigmentation, and penile development are generally 11-12 years old, with pubic hair development ranging from 12-13 years old. Axillary hair, acne, voice changes, and first ejaculation is 14-15 years old.

Height can also provide a certain reference for determining whether a child has precocious puberty. Adolescence is an important period for male and female growth. When girls begin to develop from breasts, boys with a height increase of 8-10 centimeters start from the middle of puberty when their testicles reach 10-12 milliliters (about 13.5 years old), and their height increase reaches 10-14 centimeters. The height increase throughout adolescence is about 20-25 centimeters for girls and about 25-28 centimeters for boys. Deviating from the above pattern may lead to precocious puberty or delayed development.

Generally, the factors affecting adolescent development include genetic factors, body mass index and fat content, pesticides, detergents, soybean isoflavones and other environmental chemistry, chronic diseases, etc.
