There is usually no particularly clear age limit for circumcision. However, circumcision at too young an age is not recommended. This is because it is difficult for children too young to cooperate with the surgery and most of them need to be under general anesthesia, which is more damaging to the body. Circumcision is usually recommended for children over the age of 7. When children are older than 7, they can tolerate local anesthesia. Local anesthesia is only subcutaneous infiltration anesthesia at the root of the penis, spongy body, local anesthesia compared with general anesthesia, less damage to the body. Circumcision of circumcised patients before pubertal development can make the penis grow without the constraint of the foreskin and can develop normally. However, if problems such as phimosis, chronic circumcision, or phimosis develop, surgery can be performed despite the age. The prepuce means that the glans cannot be exposed, and the long-term stimulation of foreskin scale may lead to inflammation of the glans, or even tumors, so patients with prepuce must go for surgery as early as possible; if the foreskin can be turned out normally, and good hygiene can be maintained, it is not necessarily necessary to undergo circumcision. If itself has diabetes and other chronic diseases, may lead to inflammation of the foreskin, if repeated circumcision combined with diabetes patients, in the blood sugar control after normal can also go to circumcision. Therefore, there is no age limit for circumcision, but it is recommended to go to a regular hospital to consult a professional doctor, who will then determine whether circumcision is necessary.
