Why Are Penises Shaped the Way They Are?

Penises come in all shapes and sizes, but most have something in common. Whether they're long or short, thick or thin, circumcised or uncircumcised, they all have this mushroom-like head at the end, which scientists call the glans. But why are penises shaped the way they are? It turns out there's a very specific reason and it's got to do with biology and love rivals.

During sexual arousal, there's increased blood flow to the glans and this gives it its rounded appearance. Some experts believe this is to help us reach orgasm faster by enhancing the contact between the head and vagina.

But the glans has other important functions too. According to evolutionary psychologist Gordon Gallup, the tip of a man's penis was designed as a tool that allows him to solve a specific adaptive problem related to his reproductive success.

The coronal ridge of the glans is designed to displace semen deposited by male sexual rivals from the vagina. When you thrust during sex, this ridge scoops up the sperm from your competitor and expels it out of the body, allowing your own sperm to fertilize the egg.

But this theory doesn't have universal support among other experts. Other theories suggest that the glans is shaped this way to facilitate penetration and to provide greater stimulation during sex. The curved shape also helps protect the urethra and the surrounding delicate tissues. And the glans may even serve as a visual signal to other men that a man is available for mating.
