In children who are simply circumcised, circumcision is best performed between the ages of 10 and 12 years. At this time, the child’s organism has developed to a certain degree and is tolerant of pain, so the procedure can be performed on an outpatient basis without the need for inpatient surgery. Local anesthesia can be used and the procedure can be completed in about 15-20 minutes. At the same time, children between the ages of 10 and 12 years old can tolerate a certain amount of pain because their body functions are still developing, and they can cooperate well with the doctor and the patient, so they can finish the circumcision soon. Of course, this is not absolute and depends on the tolerance and cooperation of the child. Circumcision is performed as early as possible before the child’s puberty develops around the age of 14, and will not affect the development of the patient’s genitals or cause recurrent genital infections later. However, in the case of circumcised patients or patients with recurrent infections and other abnormalities, the age should be appropriately advanced.
