'''Keratinization''' is the process whereby the surface of the [[glans ]] and remaining [[preputial mucosa|mucosa ]] of the [[circumcised ]] [[penis ]] become dry, toughened , hard and hardrelatively insensitive by a layer of [[keratin]].<ref>{{REFweb |url=https://medical-dictionary.thefreedictionary. com/keratinization |archived= |title=Keratinization |trans-title= |language= |last= |first= |author-link= |publisher=Medical Dictionary for the Health Professions and Nursing |website= |date=2012 |accessdate=2021-03-17 |format= |quote=}}</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 appearanceand reducing sensation. The color of the [[glans penis]] in Caucasian males will vary. In [[intact]] males, the color of the glans penis is likely have a purple tint, while in [[circumcised]] and keratinized males the oolor is likely to be pinkish or flesh colored.

It was hypothesized in the past that the layers of [[keratin ]] resulting from [[circumcision ]] provided a barrier of protection against [[Circumcision and Sexually Transmitted Diseases (STD's)| 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 |last=Fink, |first=Aaron J.

Recent studies have shown this hypothesis ==De-keratinization treatment==[[Dekeratinization]] is the reversing of that process.  The [[foreskin]] provides moisture and oils to be falsethe [[glans penis]] by [[transudation]]. One study [[Foreskin restoration]] by non-surgical means has been found that there to reduce keratinization and to improve appearance and sensation. When the [[glans penis]] is "no difference between consistently covered and protected by a regrown [[foreskin]] the moisture and oils cause the keratinization of to come off gradually. Since [[skin]] is constantly dying naturally (apoptosis) and being replaced, once the inner friction and outer aspects irritation is replaced with the warm, moist, snug protection of the adult male foreskin," the new cells aren't shoved into the harsh outside world, so they stay soft and pink and that "keratin layers alone sensitive, the way they were unlikely intended to explain why uncircumcised 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 are at higher risk come to depend upon their [[restored foreskin]] for HIV infectionprotection and comfort."<ref> {{REFjournalSEEALSO}} | last=Dinh | first=MH | coauthors=McRaven MD, Kelley Z, Penugonda S, Hope TJ | title=Keratinization * [[Immunological and protective function of the adult male foreskin and implications for male circumcision]] | journal=AIDS* [[Preputial sac]] | volume=24{{LINKS}} | issue=6* [https://damagefromcircumcision.blogspot.com/p/keratinization.html The Damage from Circumcision: Keratinization] | pages=899-906* {{REFweb | url=http://www.ncbiintactaus.nlm.nih.govorg/information/pubmedfunctionsoftheforeskin/20098294 | quotetitle=We found no difference between the keratinization Functions of the inner and outer aspects of the adult male foreskin.
