The foreskin is too long to turn up, and the sebum secreted by the sebaceous glands of the foreskin will accumulate in the gap between the inner surface of the foreskin and the penis head. At the same time, urine will also penetrate into this gap and react chemically with these sebum to become scales. Scales often cause inflammation of foreskin and penis head, and long-term inflammatory stimulation will cause degeneration and deterioration of local tissues and cells of penis. If the foreskin is too long, it is recommended that you perform foreskin surgery as soon as possible to eliminate hidden dangers. At present, the treatment of redundant prepuce is mostly advanced prepuce plastic surgery in Korea, which can be completed in about 30 minutes. Postoperative beauty, leaving no scars, does not affect normal life and work. I wish you a speedy recovery.
