What is the purpose of foreskin?

The purpose of the foreskin is generally to protect the glans, promote sexual function, regulate immunity, etc., but it will gradually become shorter as the reproductive organs develop.

The foreskin is the skin covering the glans. In infants and children, the foreskin will completely wrap the glans of the penis and can be used to protect the eyes from external damage.

The nerve recovery at the junction of the mucous membrane and skin of the foreskin is relatively rich. During sexual life, the foreskin has a certain degree of mobility, which is conducive to penile erection and can increase sexual stimulation.

The foreskin can secrete cytokines and interleukins, which can stimulate the body's immune response and prevent infection by microorganisms such as bacteria and fungi.

In addition, the foreskin can also adjust the pH value and temperature of the reproductive organs.
