A penile fracture is not a broken bone. It is usually much more serious. Because you will be bleeding inside.
How can you have a penile fracture? There are no bones in your penis. Even when you have such a hard erection that you think there must be.
Here's an example: If you were having intense sexual intercourse, and your shaft came out of your partner's vagina, and then in the heat of the moment you forcefully tried to reenter and missed.... then you heard a "snap" and felt a sudden sharp pain there.... yes, you very well may have caused a "fractured penis".
The bone you thought you might have broken was most likely your tunica albuginea.
But, your tunica albuginea is not a bone. It is a very strong soft tissue. It is like a balloon that covers your erectile chambers (your corpus cavernosum and corpus spongiosum). These chambers fill with blood when you get sexually excited.
During an erection your tunica albuginea is stretched very tight when the erectile chambers fill with blood (see the diagram above). Much like when you blow a balloon up as far as it will go before popping. This is what makes your erections feel hard.
And, that is why the pain from a tear here is worse than from a broken bone. It is the same awful pain as a sprain or a torn ligament.
A fracture may also include a tear in your corpus cavernosum, your corpus spongiosum, and/or your urethra (the tube you urine and semen come out of).
As you learned, your tunica albuginea is a balloon-like covering over your erectile chambers. It is a very tough and strong tissue.
When your corpus cavernosum fills with blood, your tunica albuginea expands just like a balloon.
But, it's expansion has a limit. Just like a balloon. When it reaches that limit, your erection feels hard as a bone.
Now, when you have a hard erection, your tunica albuginea is pulled so tight that forcing it to bend even a small amount will usually make it tear, or, snap (just like pulling a rubber band too far). That is what a penile fracture is.
In a limp or flaccid state, your tunica albuginea is very flexible. You can never cause this when your shaft is limp and soft.
Normally (even though they may hurt like hell) these injuries are not life threatening. But, they can cause severe and possible permanent damage to your shaft.
If not treated properly and quickly, you could wind up with a severely bent penis. If the tear is severe, and left untreated, gangrene could set in and you could lose your penis all together.
Only a qualified medical professional will know.
If you have fractured your penis, or even suspect you have:
You should get to your doctor or an emergency room immediately.
The symptoms of a fracture, or internal penile tear, include:
Usually this kind of tear inside your erection hurts so much and so suddenly that you know exactly what has happened. And, you won't necessarily have all these symptoms.
A penile fracture actually means an "internal tear".
You are bleeding inside.
That is why things are starting to turn purple. It is a serious injury. And it should be checked by a professional as soon as possible.
As I stated earlier: If you even suspect you have just fractured your penis, go to your doctor or an emergency room immediately. Normally a penile fracture can be fixed without complications if you do it in time.
