Function of the foreskin :
- Erotic pleasure, especially via the ridged band and Meissner's corpuscles
- Acts as a rolling bearing in intercourse and masturbation
- Prevents dyspareunia (painful intercourse)
- Stimulates partner's genitalia, giving erotic pleasure
- Supplies skin to cover the shaft in erection and prevent tightness
- Stores pheromones and releases them on arousal
- Stores, releases and helps distribute natural lubricants ("smega" and pre-ejaculatory fluid)
- Makes the glans a visual signal of sexual arousal
- Provides a seal against the vaginal wall to contain semen
- Prevents the glans becoming keratinized (Hardening of the mucosa of the glans after circumcision, leading to reduced sensitivity), and keeps it soft and moist
- Protects the thin-skinned glans against injury
- Protects the nerves of the glans, retaining their erotic function
- In infancy, protects the urethra against contamination, meatal stenosis, (and UTIs?)
- Provides lysosomes ("Lysozyme protects us from the ever-present danger of bacterial infection. It is a small enzyme that attacks the protective cell walls of bacteria." "Lysozyme protects many places that are rich in potential food for bacterial growth." "Our tears and mucus contain lysozyme to resist infection of our exposed surfaces." - from Protein Data Bank Molecule of the Month, by David Goodsell, "The inner prepuce contains apocrine glands, which secrete cathepsin B, lysosyme, chymotrypsin, neutrophil elastase, cytokine (a non-antibody protein that generates an immune response on contact with specific antigens), and pheromones such as androsterone. Lysozyme, which is also found in tears, human milk, and other body fluids, destroys bacterial cell walls." - Fleiss et al) for bacteriostatic action around the glans
- Pigmented, it protects the unpigmented glans against sunburn
- Vascular (rich in blood vessels that bring heat to the tissues), it protects the less vascular glans against frostbite, as Sir Ranulph Fiennes found on his epic transpolar walk.
- Provides skin for grafts to burnt eyelids, reconstructive surgery, etc.
- "The foreskin is important embryologically in the formation of the end of the penis and the urethra. If there is no foreskin the urethral opening is not at the end of the penis where it should be, but somewhere on the underside of the penis (hypospadius is A condition in which the meatus points downward rather than forward. In the most serious cases the opening may be at the base of the penis. Hypospadias occurs in about one boy in 300 in the US. (but the rate has increased in the last three decades, and is currently one in 125 - New Scientist, 29 June 2002: exposure during pregnancy to anti-androgens and oestrogen-mimics generated by industrial pollution is suspected.) Hypospadias is an absolute contraindication for circumcision, because the foreskin can be used for its repair, but many boys with hypospadias are circumcised regardless. It may be iatrogenic, a consequence of circumcision. It may be repaired without circumcision, using the Byars' flaps technique or its "Batman excision" refinement.)." - Dr Edgar Schoen (!) (but he claims that is its only function)
- Holds absorbant tissue in place after urethral surgery, in case of minimal incontinence, etc.
