Fifteen-year-old boys can be circumcised if there are indications and no contraindications for the procedure. Circumcision is the removal of the excess foreskin from the penis so that the glans can be exposed. 15-year-old boys who are circumcised, have a small foreskin opening, are circumcised, or have an accumulation of circumcised scales in the foreskin sac, which is often accompanied by inflammatory infections, can be evaluated by a doctor and then selected for treatment with surgery such as circumcision or phlebotomy. However, if a 15-year-old boy suffers from a systemic bleeding disorder, the presence of coagulation disorders or the foreskin, glans is in the inflammatory phase, etc., the operation can not be carried out immediately, and need to be symptomatic treatment or inflammation subsides before the operation can be carried out. If there is a need for surgery, it is recommended to go to a regular medical institution in time and choose the appropriate surgery after the doctor’s assessment.
