The line under the glans is commonly referred to clinically as the prepuce. The foreskin tether is an important structure of the male penis, and the foreskin tether is rich in nerve fibers. The mucous membrane of the glans of the male penis is rich in nerve endings, and the nerve endings feel sexual stimulation through the nerve fibers, that is, the nerve fibers in the foreskin tether, to the center of the spinal cord and the brain, thus causing sexual excitement, making the penis erect and inducing orgasm, etc. Clinically common foreskin tie rupture is mainly caused by excessive force or violent intercourse during sexual intercourse in men. The fracture of the foreskin tether allows the nerve fiber conduction to be affected, often causing impotence and other conditions to occur. Therefore, it is important to actively treat a broken foreskin.
