A biological myth that many people fall for is that our foreskin is useless. However, if we can take one lesson from human anatomy, it’s that even important parts of our body can look deceivingly simple and misleadingly useless.

Take away the function of that seemingly “useless” part of your body and you soon realize the important role it plays in your life.

While many people are becoming aware of the importance of the foreskin and its specialized function, many are still unaware of the importance of a small piece of penile tissue that has remarkable functionality.

This piece of tissue is called the frenulum.

There’s a thin piece of tissue found on the underside of your glans and it connects your foreskin to the base of the penile head. This piece of tissue is elastic and works similar to the elastic tissue found under your tongue and your upper lip.

In medical terms it’s called the frenulum preputii penis or the penile frenulum. Many even casually refer to it as the banjo string.


What does the frenulum do?

Unlike the frenulum found under your tongue and your upper lip, the penile frenulum has a highly specialized function. One of its obvious functions is to act as a flexible band that always returns our foreskin back to where it should be – covering the glans.

One end of the frenulum is attached to the foreskin while the other is anchored in between the two globes of the glans. When a male is erect, the foreskin usually rolls back, allowing for the glans to be exposed. Once the male returns to the flaccid state, the recoil action of the frenulum […]
