What is the function of the male foreskin?
The male foreskin performs a number of functions. First, it directly enhances sexual pleasure via specialized erogenous nerve endings such as the frenulum, the ridged band, and stretch receptors called Meissner’s corpuscles. The foreskin also serves to protect the moist, mucous membrane of the glans (the “head” of the penis) and the inner foreskin from outside elements, similar to the way the female foreskin protects the clitoris. When the foreskin is removed, the penis is transformed from an internal organ into an external one, initiating a desensitizing process known as keratinization. Keratin is a tough, skin-like substance similar to a callus that forms on top of the nerve endings of the glans, resulting in significant loss of sexual sensitivity. The foreskin also provides a gliding mechanism during sexual intercourse that reduces friction and locks in moisture, acting as a natural lubricant. The foreskin provides a number of other important functions as well.
