Male phimosis usually occurs, and surgical treatment is recommended. The main risk of male foreskin being too long is that it is easy to hide evil and shelter evil, leading to infection of foreskin and glans penis. If the male simple foreskin is too long, and the foreskin tends to be upturned, it can be cleaned regularly to ensure cleanliness and hygiene without surgery. The phimosis mainly refers to the narrow prepuce mouth or the tight adhesion between the prepuce and the glans penis, which leads to the incomplete upturning of the prepuce. At this time, the glans penis cannot be exposed for cleaning, and the cleaning effect of any method is not good, which may lead to long-term chronic infection of the foreskin and even the risk of tumor growth for a long time.

Therefore, if a man has phimosis, it is necessary to surgically remove the longer and narrower foreskin to fully expose the glans penis and the coronal sulcus, and it is easy to observe the glans penis and the coronal sulcus without turning over the foreskin. At this time, it is easier to clean, and the risk of infection and even tumors will gradually decrease. At present, the mainstream academic view holds that surgical treatment of phimosis can significantly improve the prognosis, reduce the risk of inflammation and even cancer, and at the same time significantly improve the quality of life of patients and benefit them.
