Circumcision surgery is mainly indicated for patients who have difficulty in urinating because the foreskin cannot be turned up or the foreskin is too long, as well as in cases such as narrow foreskin opening or recurrent circumcision. Usually, circumcision surgery is performed after the age of 8, but it is not too late to have circumcision surgery at the age of 20, and the time of treatment will be decided according to the needs of the condition. The surgery is a common urological procedure and can be done early to prevent abnormal penile development in children. However, it is not too late for a 20-year-old male to have the surgery. After having the circumcision surgery at this time, you can effectively avoid bacterial and fungal infections, and also effectively reduce the occurrence of glansitis and urinary tract infections. When having sex, you can also avoid cross-infection, which is beneficial to the health of the other half. At the same time, circumcision can also reduce the chance of penile cancer and also have the effect of preventing genital lesions. If you are 20 years old and have a circumcision, you should go for the surgery as soon as possible and usually choose circumcision. The wound may bleed due to the erection of the penis.
