How to judge if an 11-year-old boy has precocious puberty

Patient's question:

Boy, 11 years old, voice change for 3 months, penis enlargement, growth of pubic hair, testicles enlarged

Doctor's answer:

The purpose of drug treatment is to improve the adult height of the child, and attention should also be paid to preventing psychological problems caused by precocious puberty and early menarche. GnRH analogs are generally used to treat CPP. Currently, in China, there are sustained-release GnRHa formulations for children available, such as triptorelin and leuprolide acetate.
