Circumcision is a condition in which the foreskin covers the glans and can be turned up to expose the glans and urethra. Most Asian men are circumcised. In the case of long foreskin, the secretions in the inner plate of the foreskin are not easily removed and the local humidity is easy to lead to the reproduction of bacteria and the occurrence of foreskin glansitis. Repeated occurrence of foreskin glansitis is also a high risk factor for penile cancer. Meanwhile, the foreskin covering the glans for a long time can lead to increased sensitivity of the glans and cause premature ejaculation. So, do all circumcised people need surgery? Circumcision is needed in the following cases: 1. If the foreskin is too long with narrow foreskin opening, when the penis is erect during sex, the foreskin will flip up to the back of the coronal sulcus, which may cause local discomfort and affect sex life, but also may lead to foreskin inlay, resulting in edema of the glans, and in serious cases, may lead to necrosis of the glans. 2. If the foreskin is too long, although the opening of foreskin is loose and will not cause foreskin imposition and discomfort of sex life, but if glans prepuce occurs repeatedly despite the daily attention to local cleanliness and hygiene, circumcision is also needed to prevent the occurrence of penile cancer in the future. However, although circumcision is a minor surgery, it is still a surgery after all, which may lead to adverse reactions to anesthetic drugs and complications of surgery, such as postoperative bleeding and short circumcision after surgery. Therefore, the indications for surgery should be strictly controlled. The following cases do not need to be circumcised 1. If the foreskin is too long and the foreskin mouth is loose, daily attention should be paid to: upturn the foreskin when urinating to expose the urethral orifice to avoid urine passing through the foreskin cavity, which helps keep the local clean and dry; upturn the foreskin daily to clean the foreskin cavity, try not to use bathing liquid and soap and other irritating items frequently to clean the local area; wash the local area with water before and after sex in time. If you can pay attention to the local cleanliness and hygiene to avoid glans circumcision, you can not circumcision. 2. Although the glans is exposed after circumcision, which increases the friction with underwear and can reduce the sensitivity of the glans, it is usually futile for patients suffering from premature ejaculation to extend their sex life by circumcision.
