The foreskin is a layer of skin that protects the penis. Under normal circumstances, it will adhere tightly to the penis during the initial stage, and then separate from the penis by itself, and can be turned out to expose the glans. If some boys have phimosis (which means the foreskin is too tight), it can cause repeated inflammation of the urethra and the foreskin. A “circumcision” could be performed to reduce the risk of infection and inflammation in the area.
