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