Ignorant people out there have compared male foreskins to wisdom teeth to justify circumcision on completely healthy children. They say foreskins are vestigial and useless. I have to disagree.

Here is a study proving that humans' foreskin is not vestigial like wisdom teeth, in fact, humans' foreskin is an evolutionary advantage.

In this long [Study], they concluded:

The results of this study demonstrate that the human prepuce is not vestigial but is, in fact, an evolutionary advancement over the prepuce of other primates.
[...]
Removal of the prepuce disturbs normal copulatory behaviour in mammals, including humans

According to them, mammals' penile glans is covered by the foreskin/prepuce when flaccid for several reasons:

  • Protection: The foreskin acts as a protective layer, shielding the sensitive glans from friction, abrasion, and environmental irritants.
  • Sensory Function: The foreskin contains a high concentration of nerve endings, making it an erogenous zone that enhances sexual pleasure.
  • Hygiene: The foreskin helps to maintain moisture and cleanliness, reducing the risk of infections.
  • Evolutionary Advantage: In many species, the prepuce may have provided an evolutionary advantage by protecting the glans during movement and other activities.

Almost all mammal species have prepuce/foreskin. Only a small number of mammal species lack a prepuce. Specifically, monotremes, which include the platypus and the echidna, do not have a prepuce. Monotremes are egg-laying mammals and are quite distinct from other mammals in several ways.

There are good reasons why mammals have foreskin, and there are even better reasons why humans (still) have foreskin just like other mammals.

Here are some proven foreskins' fuctions in humans:

  1. Foreskin covers and protects the glans (the pink head of the penis) from: fabric friction, unwanted stimulations, keratinization, and from desensitization. Having your glans constantly exposed and rubbed against fabrics all the time will result in desensitization and keratinization. Can you see how rough the fabrics you wear are compared to the internal canal of the female genitalia (vagina)?
  2. Foreskin has a gliding function that acts like lube. Foreskin gliding up and down feels much more pleasurable and is more convienient than using lube.
  3. Foreskin keeps in moisture, prevents drying. It keeps the glans plump, smooth and shiny.
  4. Foreskin also has cells (such as Langerhans cells) that secrete immunoglobulin antibodies & antibacterial and antiviral proteins, including pathogen killing enzyme lysozyme.
  5. Foreskin itself has plenty of nerve-endings. It has coiled fine-touch receptors called Meissner's corpuscles, dorsal nerve branches, and specialized erotogenic nerve endings of several types.
  6. Foreskin itself has plenty of veins and blood vessels, including the frenular artery and branches of the dorsal artery, which increases blood flow to the shaft and glans of the penis.

I post this here because men deserve to know the truth about their bodies, and to understand why they should protect themselves and their sons from harm.
