When you become sexually aroused, blood flows into spongelike spaces inside your penis, expanding and stiffening it. A bent penis generally occurs when these spaces don't expand evenly. Most often, this is due to normal differences in penis anatomy, but sometimes scar tissue or another problem causes a bent penis and painful erections.

Possible underlying causes of a bent penis include:

  1. Peyronie's disease (a curved erection caused by one of a number of underlying conditions)
  2. Injury to the penis
  3. Autoimmune disorder
  4. Inherited fibrous tissue (collagen) abnormality

Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
