Because the penis develops rapidly during puberty, circumcision is usually recommended before the development of puberty, which may be most appropriate around the age of 10, and it is generally recommended that circumcision be completed before puberty develops. Circumcision is the classic surgical procedure for the treatment of circumcision. There has been clinical controversy as to when or at what age to circumcise a child. Children with circumcision tend to heal themselves around the age of 3, so newborns can wait until after the age of 3 before considering circumcision after birth. The reason why surgery is required before puberty develops is because the circumcision or prepuce may have an impact on the development of the genitals. In addition, if recurrent episodes of glans penis seriously affect the treatment of life and the psychological growth of the child, circumcision can be performed earlier. Therefore, it is best to recommend that patients undergo surgical treatment before puberty develops. With the application of disposable circumcision device, the operation time is greatly shortened, and it is more convenient for the child to undergo surgery under local anesthesia. To sum up, the best age for circumcision is around 10 years old, as it does not affect the development of the genitals and the child has some control over it, so it can be done under local anesthesia.
