Because surgery will bring complications and psychological shadows to some children, doctors often choose to apply ointment locally first. Safety and standardization are the premise of circumcision.

After all, circumcision is not cutting cabbage, but doing surgery. No tissue in the human body is useless. The foreskin can cover Tintin's head and play a protective role. Its secretion contains cytokines, which can protect the internal urethral orifice from infection and has immune protection.

This mucosa of the foreskin can also prevent Tintin from becoming sensitive due to friction with underwear, which can reduce the incidence of premature ejaculation in adult men. Therefore, foreskin is very useful for male reproductive health.

Unless it is pathological phimosis, dysuria, repeated inflammation, hypertrophy and edema of the foreskin, loss of elasticity and swelling of the foreskin, inability to retreat upward and urethral stricture (when a child urinates, Tintin's front end will bulge like a balloon and the urine will be as thin as a line) or the foreskin is too long.
