Some men have a penis that curves to the side, upward or downward when erect. This is common, and a bent penis in most men isn't a problem. Generally, a bent penis is only a cause for concern if your erections are painful or if the curvature of your penis interferes with sex.
Possible underlying causes of a bent penis include:
- Normal differences in penis anatomy
- Autoimmune disorder
- Inherited fibrous tissue (collagen) abnormality
- Injury to the penis
- Peyronie's disease (a curved erection caused by one of a number of underlying conditions)
Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
