Peyronie’s Disease

XIAFLEX® Injections

A curved erection caused by Peyronie's disease may happen because of a problem in the way the body heals after an injury (a connective tissue disorder).

When this happens, the body doesn't properly control how much scar tissue develops and too much builds up gradually. A bump of scar tissue forms under the skin of the penis. This bump is called a Peyronie's plaque.

Peyronie's disease is unlikely to go away on its own, and may get worse over time.

Erectile curvature can vary greatly from man to man. You could have Peyronie's disease with a curve ranging anywhere from 15 degrees to more than 90 degrees.

XIALFEX® is administered via injection into the penis, and is indicated to treat adult men with Peyronie's disease who have a "plaque" that can be felt and a curve in their penis greater than 30 degrees when treatment is started.
