Abnormal Penis Shapes: What Causes Them?

Like all humans, the penis can also come in all shapes and sizes! Even with identical twins, there will be variations in its appearance. Nevertheless, there are still certain differences that might end up being considered as abnormalities.

There are ways to address these irregularities, but you first must learn about what causes them. With that said, check out the most common causes of penile abnormalities, particularly when it comes to its shape.


Typical Penis Shapes

As mentioned, no two penises are precisely the same. In fact, most penises are asymmetrical, so it’s completely normal to have a differently shaped penis. As long as it functions normally, there’s no need to be concerned.

With that said, here are the usual variants of penis shapes:

  • Straight
  • Curved (either upward or downward)
  • C-shaped or curved sideways
  • Narrow base with a larger head and vice-versa


Causes of Abnormal Penis Shapes

On the other hand, there are some whose penis shapes are considered abnormal. These often mean deformities that can significantly affect the penis’s function and overall health. In these cases, it’s crucial to know what causes these abnormal shapes.

So, what are the usual causes of abnormal penis shapes?


Various devices to increase penile length and size are now becoming incredibly popular. However, you must be careful when using one because it might cause damages, particularly narrowing.

Narrowing often happens when a man uses too much weight to increase their penile length. The excessive weight will stretch their penis too much, resulting in a longer but narrower penis.

This can pose problems in the intimacy department because many women tend to value girth more than length.

        2.Penile Fractures

Penile fractures are another common cause of abnormal penis shapes. Although the penis doesn’t technically have a bone, it can still experience a fracture.

Penile fractures occur when the tunica albuginea tears after the penis is severely bent while erect. The tunica albuginea is a spongy group of tissues underneath the skin. It’s what allows the penis to increase in size during an erection. 

After it’s torn, that area’s blood spreads to other tissues, causing bruises and inflammation. It’s vital to see a doctor if you suspect a penile fracture. This is because not immediately addressing fractures may leave your penis permanently damaged. 


Penile curvatures refer to abnormal bends in the penis that you can observe during erections. There are different reasons for abnormally curved penises, such as:

  • Congenital or in-born
  • Trauma or injuries to the penis
  • Hypospadias
  • Peyronie’s Disease

Mild cases of penile curvature often don’t require treatment. However, suppose it significantly affects intercourse or its overall function. In that case, you can opt for surgery or use extenders to correct its shape and restore its normal function.

      4.Peyronie’s Disease

Peyronie’s Disease is slightly distinct from normal penile curvatures because of what causes the abnormal shape. Peyronie’s Disease happens when scar tissue builds up in your penis, affecting its shape and appearance, particularly while erect.

Some attribute the cause of Peyronie’s Disease to injuries. Some believe that it’s because of one’s genes or underlying conditions like auto-immune disorders.


Phimosis refers to the condition wherein you can’t retract your penis’s foreskin. While a tight foreskin is common in boys who can’t be circumcised, this can be problematic for adults. This is because it can interfere with erections and even urination.

This condition can occur naturally, but other causes include infections and inflammation like Balanitis. 

Some recommend using a penile traction device or extender to make the penis’s foreskin wider naturally. 



Penises come in various shapes and sizes, so it’s perfectly normal to have an asymmetrical penis. However, some conditions can cause abnormal penis shapes that can sometimes affect your penis’s health and functions. 

Identifying and understanding their causes will help you find suitable solutions to address these problems.
