Why is it permissible to remove the mucous membrane, which plays an important role in immunity?

Thank you for your questionOne should not remove the hood period. The hoodoplasty procedure is resecting the excess tissue hiding the clitoris so that it can more easily be exposed during intercourse. You may be confusing this with reduction of prepuce. There are two pair of inner labia. A lower pair that inserts into the clitoris and an upper pair, called prepuce, which forms the hood and have excess skin which frequently enters into and can overwhelm the lower pair. When the prepuce is reduced it should not involve the hood itself.When the hood is reduced it almost always involves a very minimal amount of epithelial tissue which in no way would effect immunological status. The video below on labiaplasty touches on the subject of prepuce and may be of help understanding

A properly performed clitoral hood reduction should involve removal of a limited amount of skin only above the clitoris and should not have any impact on the mucocutaneous function. It is true that this delicate operation can be done incorrectly or "over-corrected" with too much skin excised. It is therefore critical that you consult with an experienced board certified plastic surgeon or gynecologist well versed in the procedure. Best of luck to you.

It's never a good idea to remove the clitoral foreskin. Doing so would expose the head of the clitoris ro constant friction against clothing and would be a source of chronic pain. Your quote is a reference to removal of the male foreskin and the source you quoted it from was probably in error. Nonetheless, the clitoral hood should never be removed unless it is diseased.

Thank you for your appropriate and thoughtful question. There is much confusion when it comes to discussion of the "...Clitoral Hood." I'll try to clarify. Think of the hood as the foreskin of the clitoris, the same as a man has (at birth) a foreskin over the glans (the "head") of his penis. As the foreskin is a structure separate from the head (or "glans") of the penis, the hood is an attached but separate structure from the clitoris (which is made up of "glans" (head), shaft (or "body"), "knee" (where it takes a right angle to go under the pubic bone (like a mans penis takes an angle to "root" into the testicles.) The "root" of the clitoris consists of the "crurae" and "bulb," erectile structures that occupy, along with nerves from the autonomic nervous system, Grafenberg's area, colloquially known as the "G-Spot. The hood consists of different areas, the central hood (the little "hoodie" that covers the clitoral glans); the lateral portions of the central hood which; the folds from the underside of the clitoral glans (called the "frenular folds") and the prepucial fold (or prepuce), variable folds more laterally placed on the hood, which frequently "anchor" in to the lateral (or outer) portion of the labia. These variable folds continue "downward" to make up the labia, and are frequently reduced during a labiaplasty( labial reduction.) While "connected," the labia and clitoral hood are considered anatomically to be separate structures. NOW-- to answer your question: The hood proper is covered not by mucosa, but by a "squamous epithelium." This is the "covering" that is reduced during hood reduction. The human body has different tissue types that "cover" underlying tissue. Most common externally is the somewhat thickened, cornified covering known as "squamous epithelium." This is the external covering of your clitoral hood, most of your vulva, etc. -- what most persons call "...skin..." Mucosal epithelium is that pinkish tissue found in your mouth, your vagina, your vulvar vestibule, and- yes- on the underside of the central clitoral hood directly over your clitoral glans. The "correct" way to reduce what some women feel is "excessive" epithelium (redundancy) of the clitoral hood is to, in a variety of ways (that's why you want to go to an experienced surgeon!) excise kayak-shaped ellipses of epithelium only (very superficially, so as not to injure nerves that travel deep) from each side of the hood, sort of like smoothing out the center of the bedsheet by tucking in the sheets on either side. You do not want to operate on the central hood, removing tissue directly over the clitoral glans, as that can cause scarring, exteriorization of the glans, and- often- pain. Regarding "immunological importance because they may be a point of entry of mucosal vaccines..," this does not make sense to me. Bottom line: 1. The clitoral hood is not the clitoris; 2. It can be safely reduced if its redundancy is causing functional or significant aesthetic issues; 3. "...If it ain't broke, don't fix it. No reason to reduce the hood if not part of your aesthetic or functional issues. If you do have it worked on: ONLY by a well-experienced surgeon.. Hope this helps...
