'''Keratinization''' is the process whereby the surface of the [[glans]] and remaining [[preputial mucosa| mucosa]] of the circumcised penis ~~become~~ dry, toughened and ~~hard~~.<ref>{{REFweb

Prior to [[circumcision]], the protected and covered [[glans penis]] is very smooth and has a glossy, shiny appearance. It is usually very sensitive to touch.

'''Keratinization''' is the process whereby the surface of the [[glans]] and remaining [[preputial mucosa|mucosa]] of the [[circumcised]] [[penis]] becomes dry, toughened, hard and relatively insensitive by a layer of [[keratin]].<ref>{{REFweb

}}</ref> Normally, the glans is covered by the [[foreskin]], which moisturizes the area by [[transudation]], keeping the surface of the glans and inner mucosa moist and supple. After circumcision, however, the glans and surrounding mucosa become permanently externalized, and they are exposed to the air and the constant abrasion of clothing. These areas dry out, causing layers of keratin to build, giving the glans and remaining mucosa a dry, leathery appearance and reducing sensation.

The color of the [[glans penis]] in Caucasian males will be changed by [[circumcision]]. In [[intact]] males, the color of the glans penis is likely have a purple tint, while in [[circumcised]], keratinized males the oolor is likely to be pinkish or flesh colored.

== Keratin as "Protection" ==

It was hypothesized in the past that the layers of keratin resulting from circumcision provided a barrier of protection against sexually transmitted diseases. In 1986, the late circumcision-advocate [[Aaron J. Fink]] invented the idea, without any evidence, that circumcision could prevent the transmission of HIV, arguing that the hard and toughened glans of the circumcised male resisted infection, while the soft and sensitive foreskin and glans mucosa of the intact male were ports of entry.<ref>{{REFjournal

Recent studies have shown this hypothesis to be false. One study found that there is "no difference between the keratinization of the inner and outer aspects of the adult male foreskin," and that "keratin layers alone were unlikely to explain why intact men ~~are~~ at higher risk for HIV infection, however keratinization of the glans penis was not measured."<ref>{{REFjournal

==~~Treatment~~==

==De-keratinization treatment==

[[Dekeratinization]] is the reversing of that process.

[[Foreskin restoration]] by non-surgical means has been found to reduce keratinization and to improve appearance and sensation. When the [[glans penis]] is consistently covered and protected by a regrown [[foreskin]] the moisture and oils cause the ~~keratinization~~ to come off gradually. ~~Increased~~ sensation has been reported by many restored men.

The [[foreskin]] provides moisture and oils to the [[glans penis]] by [[transudation]]. [[Foreskin restoration]] by non-surgical means has been found to reduce keratinization and to improve appearance and sensation. When the [[glans penis]] is consistently covered and protected by a regrown [[foreskin]] the moisture and oils cause the [[keratin]] to come off gradually.

Since [[skin]] is constantly dying naturally (apoptosis) and being replaced, once the friction and irritation is replaced with the warm, moist, snug protection of the inner [[foreskin]], the new cells aren't shoved into the harsh outside world, so they stay soft and pink and sensitive, the way they were intended to be. The surface of the glans penis gradually becomes softer, smoother, more glossy, and increased sensation has been reported by many restored men.

As the [[glans]] becomes more and more sensitive, restored men come to depend upon their [[restored foreskin]] for protection and comfort.
