Penile Fracture: The Surprising Thing That Can “Break”

Article By

~ November 2021 ~ Is it true that a man can break his penis? The short answer is yes, but what exactly is a penis fracture?

During an erection, the penis is engorged with blood. If the penis is bent suddenly or forcefully while it’s engorged, the trauma may rupture the lining of one of the two cylinders in the penis (corpus cavernosum) responsible for erections — resulting in a penis fracture.

The trauma is usually related to aggressive activity, including sex, and, in some cases, aggressive masturbation.

A penis fracture is a painful injury that’s often accompanied by an audible cracking sound, followed immediately by dark bruising of the penis due to blood escaping the cylinder. In some cases, the tube that drains urine from the body (urethra) may be damaged as well, and blood may be visible at the urinary opening of the penis.

In order to really understand a penile fracture, we need to give you a refresher course in biology: Your penis consists of three cylindrical tubes. The two larger tubes are called the corporeal bodies—think of them as “balloons”—that fill up with blood when you become hard.

The “skin” of these balloons is the tunica albuginea, a tissue that expands both length- and width-wise during an erection.

The third, smaller tube—located on the underside of your penis—is your urethra, from which you urinate.

When you get aroused, blood rushes into those two larger tubes, and the pressure grows. That makes your penis rigid and hard to bend. So if it experiences some kind of force—like if you accidentally hit your girlfriend’s perineum during sex while thrusting, or she moves it too much when grinding on top—it can lead to pressure overload.

When the surrounding tissue that’s holding the pressure inside can’t withstand it anymore, that’s when the rupture occurs.

Penile fractures happen only when you have an erection. When you’re soft, the pressure inside your penis is low, so it’s more able to bend and withstand unexpected forces.

A penis fracture requires urgent medical attention. A penis fracture can usually be diagnosed with a physical exam. A prompt surgical repair is also typically recommended. If left untreated, a penis fracture may result in deformity of the penis or the inability to have or maintain an erection (erectile dysfunction).

So what do you need to do if you have one?

First, the doctors at the ER can confirm your penile fracture through a clinical exam and also by tests like a urethrogram, an MRI scan, or a cavernosogram, which is an X-ray of the penis.

You’ll usually require surgery to repair the tear in your penile tissue. And it’s important that you go under the knife within 3 days of the injury. This isn’t a wait-and-see condition—if you put it off too long, you can raise your risk of complications down the line.
