Firstly, Peyronie's Disease is not actually a disease and is caused by scar tissue, called plaque, that forms inside the penis. It results in a curved penis, in some instances up to 90% curvature although anything less than 10% is considered normal.
Peyronie's Disease is much deeper than physical and could include sexual, psychological, and social effects.
It is linked to erectile disfunction and depression and can in some instances, cause relationships to break down.
It is thought that Peyronie’s Disease could impact up to 10% of males however, most cases go unreported.
