At present, you can see small advertisements for the treatment of circumcision, prepuce infection and foreskin stenosis everywhere; there are also a variety of “new technologies” on TV and the Internet, and the people who do these advertisements regard “foreskin” as the enemy of men and a public hazard to women, so circumcision It has become very popular. In addition, many teenage men on vacation every summer will also go to the hospital to consult circumcision, so it is necessary to understand this disease objectively from a scientific point of view. In fact, circumcision is the removal of excess foreskin from the head of the penis, so that the head of the penis is exposed, is a small operation for the treatment of prepuce and circumcision, the operation generally requires only local anesthesia in the outpatient clinic, the process is about 30 minutes. There are two main indications for the surgery: 1. Recurrent infection due to prepuce or prepuce. 2. Circumcision combined with narrow foreskin mouth, the foreskin will nestle the head of the penis or simply cannot retract and reveal the head of the penis. However, simple circumcision does not require surgery if you can keep it hygienic and clean. Myths: 1, foreskin useless theory: men have different lengths of foreskin, is a normal male physiological structure, the role of glans protection; foreskin gland has a secretory function, with the glans to keep slippery, from abrasion, keep sensitive and prevent the role of bacterial invasion; foreskin contains a lot of nerves and sexual stimulation closely related. Therefore, generally speaking, the advantages of foreskin outweigh the disadvantages. 2, early circumcision is good: some western countries children cut the foreskin after birth, in fact, is not scientific. The prepuce in childhood is normal and can disappear on its own with the development of the penis, and should not be operated if there are no complications. Especially since the penis is more exposed in childhood, premature removal of the foreskin will increase the risk of mosquito bites and trauma to the glans. Even if there are foreskin adhesions and mild stenosis, you can often help the child to turn the foreskin up and clean it and expand the foreskin opening. 3, the blind pursuit of new technology: the advantages of the standard surgical method is that the cut edge is neat, healing fast, bleeding very little; “laser knife” excision bleeding very little, but the laser treatment of the cut edge healing later; ring ring ligation cut edge Qi but discomfort is obviously good high cost, in fact, several surgical methods have their advantages and disadvantages, suitable is the best. And more “advanced” Korean plastic surgery technology, American-style circumcision, red light irradiation, etc. In addition to the cost and advertising differences, it really can not see what the substantive differences. 4, the theory of surgical danger: the general public will worry about surgery bleeding, pain, infection, etc., in fact, the surgery bleeding is very little, pain only in playing local anesthetic when there is the same feeling as a needle, and anesthesia will not cause any harmful effects on the penis, the penis is rich in blood supply, almost no infection; the risk of other complications is also completely within the control, do not need to be nervous.
