The idea that the foreskin is "dirty" or "unclean" is a scientifically unfounded superstition. The [[intact]] [[penis]] is naturally clean and maintains a level of hygiene that is optimal when compared to a [[penis]] that has been altered by [[circumcision]].<ref name="fleiss-hodges-vanhowe1998" />

In comparison, due to the open wounds and raw [[bleeding]] flesh in a diaper, the [[circumcised]] [[penis]] needs much more care after [[circumcision]]. The surgically externalized [[glans]] is dirty rather then clean because of constant exposure to dirt, abrasion, pathogens, and contaminants.<ref name="vanhowe1997">{{REFjournal

==Conclusion==
Most mammals have a foreskin. The [[foreskin]] evolved over millions of years to provide protection in difficult environments against [[trauma]] and [[infection]]. The various protections described in this article work best when the foreskin is of sufficient length to securely cover and protect the [[penis]] with the tip of the foreskin puckered closed by the [[dartos]] fascia at all times to protect against entry of irritants and pathogens. Urine has a healthy microbiome<ref name="cold-taylor1999">{{ColdCJ TaylorJR 1999}}</ref> when it leaves the urethra and is helpful for flushing out the [[foreskin]] and keeping it clean.

Many ill-informed sources will advise [[foreskinned]] men to retract their [[foreskin]] and wash their [[penis]] at least daily. This advice ignores the findings of medical science.<ref name="birley1993" /> Retraction of the foreskin provides an opportunity for pathogens to enter. Washing removes the protective substances found in the [[preputial sac]].

Washing with warm water is recommended before and after a sexual encounter and as necessary to remove accumulated [[smegma]]. The use of soap, body wash, and shampoo in the [[preputial sac]] should be avoided.
