Foreskin fragrance: Wikify.
'''{{FULLPAGENAME}}''' is the term applied to the space on the [[intact]] [[penis]] between the [[prepuce]] and the [[glans penis]].<ref>{{REFweb

}}</ref> The preputial sac may also be called the '''sub-preputial space''' or '''preputial cavity'''. [[Circumcised]] men do not have a preputial sac.
==Description==
}}</ref> so it cannot be [[Infection| infected]]. The preputial sac will remain closed for a variable number of years.
The preputial sac is lined with [[mucosa]] as is appropriate for an internal organ where moisture is present.<ref name="cold-taylor1999">{{ColdCJ TaylorJR 1999}}</ref> [[Urine ]] and other sources of moisture are not harmful to it.
The [[glans penis]] (head of the [[penis]]) is covered and protected from friction and abrasion by the [[foreskin]] while it is in the preputial sac, so it does not accumulate [[keratin]], and maintains its [[Foreskin sensitivity| natural sensitivity]].
}}</ref> Moistness also may be maintained by [[transudation]].<ref name="cold-taylor1999" /> The sac may vary from very slightly moist to wet.
A longer [[prepuce ]] helps to keep out contaminants and pathogens. <ref name="fleiss1998">{{FleissP HodgesF VanHoweRS 1998}}</ref> Lakshmanan & Parkash (1980) described the muscle fibers in the [[prepuce]] (known as the [[dartos]]), which contract to keep the prepuce snugly close to the [[glans penis]].<ref>{{REFjournal

}}</ref> The muscle fibers form a whorl at the tip to keep the tip of the [[foreskin]] and keep the preputial sac closed against the outside world and contamination.<ref name="fleiss1998">{{FleissP HodgesF VanHoweRS 1998}}</ref>
Cold & Taylor (1999) described a healthy [[microbiome]] that lives within the preputial sac.<ref name="cold-taylor1999" /> They also reported that Langerhans cells are found in the mucosa of the preputial sac. [[Langerhans cells]] are part of the immunological defenses of the [[penis]].

=== Foreskin fragrance ===
The [[foreskin]] produces [[pheromone| pheromones]] that are likely to be present in the preputial sac.<ref name="fleiss1998" /> Some [[foreskinned]] men report a pleasant musky fragrance<ref name="vocabulary2024">{{REFweb

The [[foreskin]] produces [[pheromone| fragrance may contain stimulating pheromones]] that are likely to be present in the preputial sacand is variously characterized. A few find it offensive, but others find it attractive, pleasing, exciting, stimulating, or arousing.<ref name="fleiss1998vocabulary2024" /> Some believe that the use of soap in the preputial sac harms the natural [[microbiome]] and increases the strength of the fragrance. The musky foreskin fragrance may be contained by avoiding retraction of the [[foreskin]].
==Washing==
Birley et al. (1993) studied 43 men with recurrent or persistent [[balanitis]] at an outpatient genitourinary disease clinic in London, [[United Kingdom| UK]] where most men are [[intact]]. Of the study group only 33 percent were [[circumcised]]. Birley and colleagues discovered that the men in that group washed frequently with soap.  The men were instructed to wash less frequently, to stop using soap, and to treat with emollients. The soap and shower gel apparently removed the natural skin oil, which appears to be essential for health of the [[mucosa]] of the preputial sac.<ref name="birley1993">{{REFjournal

== Urination==
[[Intact]] men sometimes ask, "do I have to retract my [[foreskin]] when I pee?" They may have been heard myths that it is unhealthy to have [[urine]] inside the [[foreskin]], however there is no factual basis for that claim. Urine is normally sterile has a healthy microbiome<ref name="cold-taylor1999" /> when it leaves the urethra and is helpful for flushing out the [[foreskin]] and keeping it clean. Boys by necessity pee through their [[foreskin]] because it does not retract and men with [[phimosis]] also pee through their foreskin because the foreskin does not retract. It does no harm so it is not necessary to pull back when you pee.
Everything in the preputial sac is covered with [[Mucosa| mucosal membrane]] (similar to the inside of your mouth), which likes to be wet, so no damage or threat to health is caused by having urine inside the [[foreskin]]. The sphincter action of the preputial orifice functions as a one way valve, blocking the entry of contaminants and pathogens while allowing the passage of urine.<ref name="fleiss1998" /> The [[urine ]]will help to flush contaminants and pathogens out of the [[foreskin]]. Some individuals may experience [[ballooning of the foreskin]], which is harmless.
