Due to the chronic stimulation of foreskin scale and inflammation, penile cancer can be induced. After turning the foreskin with force, foreskin inlay may occur. Inflammatory edema of foreskin caused by foreskin inflammation makes the foreskin mouth tightly embedded in the head of penis, which aggravates the edema of the head of penis and foreskin, and ischemic necrosis occurs in serious cases. Long-term chronic inflammation can cause narrowing of the urethral orifice and adhesion of the foreskin to the glans. In addition, prepuce can also lead to premature ejaculation and impotence. If the circumcised person does not pay attention to personal hygiene, it can also cause gynecological inflammation in the spouse or sexual partner, and the long-term gynecological inflammatory stimulation of the spouse or sexual partner may also be cancerous. The treatment of circumcision: simple circumcision, should pay attention to the local cleanliness of the penis, wash often, if the foreskin can not be turned up, do not forcibly flip. If you can flip it up and wash it, you should return the foreskin to its original position after washing it to avoid causing imbedded prepuce. If the foreskin is circumcised, surgery (circumcision) is necessary. The whole procedure takes about 30 minutes, there are many kinds of surgery, the classic surgery is the scissors method and knife peeling method, the process is relatively simple, after the surgery (absorbable thread) no need to remove the stitches, available 1: 5000 concentration of potassium permanganate solution soak, after the surgery can be appropriate amount of oral anti-inflammatory drugs to prevent infection. It has little impact on work and life.
