The current age for diagnosing precocious puberty is eight years old for girls and nine years old for boys. Sexual development is a continuous and dynamic process, and the specific age is a figure derived from statistical analysis of the entire population’s sexual development, which is a landmark figure, not an absolute figure. Precocious puberty needs to be treated with intervention, should those eight or nine year olds be treated with intervention? A large number of children who come to the hospital with precocious puberty are in this situation. Some of these children started to develop after the age of eight, and some started to develop before the age of eight, but their parents didn’t notice. Precocious puberty does have some effects on children, and it is good to detect and intervene early, but it is a dilemma for both parents and doctors whether to intervene and treat these children when they are in their 80s or 90s. Whether or not to treat these children has a lot to do with parents’ expectations for their children’s height, but of course early development also brings a lot of trouble to children. Some parents want their children to grow taller, while others do not want their children to menstruate too early and want to treat them, but it is not just a matter of wanting to treat, but of considering the results of the treatment. If the goal is to improve the height, it is currently considered that the bone age of girls within eleven and a half years old and boys within twelve and a half years old can be treated, because the bone age is too old for treatment to improve the height of poor results. The treatment of these children is generally not effective with herbal medicine and usually requires injections, i.e. gonadotropin-releasing hormone analogs, treprostin and leuprolide, which usually require two years of treatment. Gonadotropin-releasing hormone analogs are more effective for breast and menstrual control.
