Causes
By Mayo Clinic staffA bent penis generally occurs when hollow spaces inside the penis don't expand evenly during an erection. When you become sexually aroused, blood flows into these spaces. This flow of blood causes an erection by expanding, straightening and stiffening the penis. Scar tissue or another problem inside the penis can cause uneven expansion of the spaces inside your penis, leading to a bent penis. Possible causes of a bent penis include:
- Autoimmune disorder
- Inherited collagen abnormality
- Injury to the penis
- Medications, especially beta blockers
- Peyronie's disease
Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
