Causes
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:
- Peyronie's disease (a curved erection caused by one of a number of underlying conditions)
- Injury to the penis
- Autoimmune disorders
- Inherited fibrous tissue (collagen) abnormality
