The [[foreskin]], like the eyelid, also serves an important protective and hygienic function. The [[foreskin]] protects provides physical protection of the delicate [[glans]] of the [[penis]] and puts the [[urethra]] at a distance from its environment, protecting it from foreign pathogens and contaminants of all kinds while simultaneously shielding the [[penis]] from traumatic injury. It is a double fold of [[skin]] which offers two layers of protection to prevent [[keratinization]] and maintain sensitivity.
