The '''preputial mucosa''' of the [[penis]] is the epithelium of the inside of the prepuce, or [[foreskin]]. To differentiate it from the cutaneous [[skin]] of the outside of the [[Foreskin|prepuce]], it is sometimes referred to as the '''inner mucosa'''. It starts at the mucocutaneous junction at the tip of the [[Foreskin|prepuce]] and continues to the coronal sulcus (groove behind the [[glans penis]]), where it meets the epithelium of the glans and penile shaft.<ref name="cold-taylor1999">{{ColdCJ TaylorJR 1999}}</ref> The preputial mucosa is devoid of hair, as is the cutaneous surface.<ref name="taylor1996">{{TaylorJR LockwoodAP TaylorAJ 1996}}</ref> | The '''preputial mucosa''' of the [[penis]] is the epithelium of the inside of the prepuce, or [[foreskin]].

Fleiss et al. (1998) report the inner [[mucosa]] contains apocrine glands, which secrete cathepsin B, lysozyme, chymotrypsin, neutrophil elastase, and hormones such as androsterone. The first four substances have protective immunological functions.<ref name="fleiss-hodges-vanhowe1998">{{ | Fleiss et al.

After circumcision, the residual [[mucosa]] is found between the [[circumcision scar]] and the [[glans penis]]. The [[mucosa]] is no longer moisturized by [[transudation]] from the [[foreskin]] and becomes desiccated. | After circumcision, the residual [[mucosa]] is found between the [[circumcision scar]] and the [[glans penis]].
