1. Advantages of circumcision: Circumcision can prolong sexual life, avoid cross infection, reduce the probability of penile cancer, promote the growth and development of male genitals, prevent inflammation from worsening, prevent abnormal development of glans penis and prevent infertility.

2. Disadvantages of circumcision: Because private hospitals unilaterally publicize the benefits of circumcision, many people inexplicably found that it was completely different from what they expected after the operation. Surgery inevitably cuts off a part of the frenum, which is one of the three sensitive areas of men, thus affecting men's experience of pleasure and even causing sexual apathy. If the male friend's foreskin is too long, he should go to the hospital for examination and receive corresponding treatment in time, so as not to affect his daily life and cause some harm to his body. Remember never to avoid medical treatment.
