The foreskin should not be removed arbitrarily if it is not too long, in order to avoid sequelae such as penile injury, short foreskin and postoperative infection, which may affect normal function. For men with normal foreskin length, removing the foreskin by means such as circumcision carries the risk of surgical failure, which may lead to penile injury and affect the erectile function of the penis. In addition, removal of the foreskin may also result in a short foreskin tie, which can cause painful tugging during erection and can also affect normal sexual function. After circumcision, there are other risks such as infection and scar formation at the incision, which are not conducive to reproductive health, and hospitals usually do not perform the surgery on men with normal foreskin length. Any abnormal symptoms in the male reproductive organs should be treated in a timely manner in a urology clinic under the guidance of a specialist. Whether or not surgery is needed should also follow medical advice.
