The 6 bent penis causes are:

  • Genetic

  • Peyronies Disease

  • Fractured Penis

  • Stretching

  • Autoimmune Disease (and certain medications)

  • Circumcision

Let’s take a look at each one:

The 6 Causes
in detail

Let’s discuss the first of the bent penis causes: slight curvatures. Because they really need no attention or correction. We’ll work our way up to the most severe and problematic ones last.

bent penis cause #1:

The Genetic Bent Penis

bent penis causes

This type of curvature is usually very mild. It does not interfere with sexual intercourse. And, sometimes women find it quite lovely.

Over half of all men have a small curvature in their erection. You didn’t know that. Did you? This type of penis curvature is nothing to be concerned about, and, you don’t need to do anything to “fix” it. It’s fine. And, it’s normal.

bent penis causes #2:

The Stretched Curvature

Just like the genetic bend, these curvatures are usually very slight.

They can be caused by continuous rough masturbation in one direction, tight clothes with your cock always in the same place, anything that constantly pulls the shaft to a certain direction.

They are very very rarely much of a bend at all.

Interestingly enough, improper or very aggressive circumcision can cause some penile curvature. And, after adult circumcision, there may even be pain during erection.

“North American men who have been aggressively circumcised –have too much tissue removed-- often have tension during erections due to penile skin sheath asymmetry.

Very commonly a circumcised male has a curved or bent penis on erection due to inadequate remaining tissue on the ventral (under) side (penis curves down), or, inadequate tissue on the dorsal (top) side (penis curves up), or even left or right.

This tension can be severe enough that it induces pain or drum-tight tension on erection, and disturbs important REM deep sleep, the time when nocturnal tumescence (erection) occurs.

The natural, intact (not circumcised) penis has a gentle upward curve as you will know, and, of course, no artificial deficit of tissue that might induce additional curvature. Any excessive curvature on an intact male might, indeed, be due to Peyronie’s.”

reference: Dr. George Denniston MD, President,

In circumcised babies, if there is a curvature later in life, it is almost always small and insignificant.

In circumcisions performed on adult males, more problems can and do occur because the tissue is not as elastic as that of an infant.

bent penis causes #4:

Peyronies Disease

A bent penis caused by Peyronies disease is what usually brings a man to this website.

Peyronies disease can deform a penis in the most severe and hideous fashion.

These erections can be painful.

PD can cause both physical erectile dysfunction, psychological ED, or both.

Peyronies takes a man by surprise in mid life, without warning. Because we are almost never educated bout this, most men don’t have any idea what is happening. The result can be devastating both sexually and emotionally.

FORTUNATELY: It is very easy to fix a bent penis 99% of the time. Without surgery, injections, or drugs.

I will get into that in detail later. If you want to skip ahead, please just click here.

bent penis causes #5:

Autoimmune Disease (and certain medications)

These bends can be just as awful as those of Peyronies disease. I was a victim of this. A full 90 degree bend to the right.

With Peyronies disease you can usually feel the scar inside that is causing the bend.

With an autoimmune disease like Dupuytren’s Contracture (what I have) you feel no bump. You just have a thickening of the tissue inside that prohibits normal stretching during erection.

Other autoimmune disease that can cause Peyronies are: rheumatoid arthritis, lupus, diabetes millitus, scleroderma, and some other less common ones.
Certain medications can also cause this tissue thickening.

There are a number of injectable drugs used on Dupuytren’s contracture. Some are reported to work.

The only FDA approved injection for PD at this time is Xiaflex® (collagenase clostridium histolyticum). A full set of these injections will cost you about $30,000 (yes, thirty thousand dollars). And, Xiaflex® comes with some serious possible side effects which include penile fracture (corporal rupture). A medical emergency. You can see the full list of the possible side effects on their website at

But, the fact is, with duyputren’s contracture, if you start stretching your hand when the tightening/bending first starts (just pull the fingers away from the tight tissue), you can keep the thickening tissue from causing a problem.

Like me, you will still be able to see the lumps of tissue in your palm, but, they will cause absolutely no problem with full functionality if they are sufficiently stretched out.

If you’re too lazy to stretch them each day (about half a minute to a minute), they will get worse and eventually take a lot more work to correct.

It you’re just learning about this now, and your fingers are already not opening up, just be patient with the stretching. It can take a while, but, it almost always works like a charm.

The entire point of that long explanation on hands is this: The same is true for stretching and straightening a bent penis caused by this autoimmune problem.

bent penis causes #6:

A Fractured Penis, Broken Penis

You probably never imagined that you could break your penis. Did you?

I saved this one for last, as the most serious, because a fractured penis needs immediate medical attention.

broken penis causing Peyronies disease

A penis has no bones. So what breaks?

What there is inside the shaft a tough thin sack that holds your erectile chambers. This sack is what makes the erection hard when the chambers fill with blood. This sack is call the tunica albuginea.

bent penis causes, tunica albuginea

A “fractured”, or, “broken penis” is what happens when this sack tears.

This tearing usually happen during rough intercourse when the erection is slightly bent (it was never meant to bend at all during erection).

In the broken penis, the tunica albuginea or the erectile chambers tear. That is what the “break” is. And, you will bleed inside.

It usually is a very sharp pain when it happens. So, it won’t just sneak up on you when you sleep.

A broken or fractured penis is a medical emergency.

You need to get to an emergency room immediately.

If you don’t, you could lose your penis (it will be amputated) to gangrene (rotting from lack of blood flow).

When a broken penis heals it can cause a bend in your erection. Either now, or, years later.

How to
Fix a Bent Penis

99% of the time, it’s really quite easy to fix a bent penis. Even with a severe bend that is causing erectile pain.

And, 99% of the time, it can be done without surgery.


Because every bend is caused by just one thing: One side of the erectile tissue is shorter than the other during erection. So the erect shaft is pulled in that direction.  *There can be more than one short spot.  So, a penis may bend in multiple directions.

This video makes it so easy to understand:

I hope you took a couple of minutes to watch that video. It will make everything I’m going to tell you now easier to understand.

To straighten the bending, all you need to do is stretch out the shorter section until it stretches as far as the longer section.

Do you see why this eliminates the need for a surgery? Or, chemical injection?

So simple!

Yes, there are a small number of men who will need surgery. But, that’s a very small number of men.

The Safest and Most Effective
Medically Recommended Penis Straightening

The Safest of all the medically recommended methods, that have proven to work consistently, is called Penis Traction Therapy (PTT)

PTT comes with none of the possible side effects of surgery or injections.

Penis traction therapy is done with a small device developed in 1994 by a penis surgery specialist named Dr. Jorn Ege Siana.

Correct penis traction can straighten out almost any curvature from all of the bent penis causes. The cost is under $300.

“I advise that penile traction therapy is initiated early as soon as signs and symptoms of Peyronie’s disease are identified and diagnosed. The goal of penile traction therapy is three-fold:

  1)  Prevent worsening of symptoms, in particular ,prevent penile shortening that affects many men with Peyronie’s disease.

  2)  Reverse penile shortening that has occurred.

  3)  Prevent and reverse penile curvature.”

bent penis causes

There are 6 bent penis causes.

The most common are Congenital curvature (from birth) and Peyronies Disease (from tissue that hardens later in life).

Penis curvature that is slight, and, that does not interfere with sexual intercourse does not need any kind of correction.

Severe penis curvature is easy to straighten 99% of the time without surgery using correct penis traction therapy.

Be Well.....
