If the male foreskin is too long, usually take surgical treatment, can perform circumcision, but not all patients with circumcision need surgery. If the foreskin covers the glans but can be completely exposed to the coronal sulcus when it is turned up, surgery is not necessarily needed. If the foreskin is too long to cover the penis, it is the so-called prepuce, that is, the coronal sulcus cannot be exposed, and even if the foreskin is turned up, the coronal sulcus cannot be exposed, so it is better to perform circumcision, the advantage of which is to prevent infection and penile cancer. There are two types of circumcision surgery, one is the traditional suture surgery, and the other is the current anastomosis surgery.
