Prevent the accumulation of foreskin scale causing inflammation. This is especially true for adolescent boys who have more circumcision. For teenagers with long foreskin and circumcision, it is best to have surgery in time. The excess foreskin will be cut off in a circle and the adhesions will be separated to completely expose the glans. In fact, circumcision can be performed with local anesthesia and does not require hospitalization. The most suitable age for circumcision for adolescents is 6-14 years old, because children before the age of 6 do not cooperate with anesthesia for surgery, and frequent erections after the age of 14 can increase post-operative pain. There are various surgical methods of circumcision, such as traditional circumcision, laser excision, and loop excision. In particular, circumcision is the easiest surgical method, and the patient suffers less pain, which basically does not affect study and work.
