What causes bent penis?

Swelling of the penis may result from several conditions. However, true bent penis in adults can be due to Peyronie’s disease or penile fracture.

Peyronie’s disease is an inflammatory condition affecting the penis. The penis may become curved or bent due to the growth of fibrous scar tissue (plaque) under the skin of the penis. The cause of Peyronie’s disease is not known, but it may be due to a previous injury to the penis or it may possibly be the result of an autoimmune disorder.

Injury during an erection may cause a bent penis resulting from a penile fracture. Sudden or forceful bending of an erect penis may rupture one or both of the cylinders in the penis that fill with blood to create an erection.
