DISEASE PROGRESSION*
If left untreated, roughly 40% of men with Peyronie's disease will experience a progression of the disease, 47% will experience no change and 13% will have disease regression over time.
Phase 1: Acute Inflammatory Stage
The acute inflammatory stage can last from 6-18 months. Sufferers may experience pain; varying degrees of penile curvature, shortening, or indentation; and the formation of a lump of scar tissue.
Phase 2: The Chronic Stage
In the chronic stage a stable plaque forms and the deformity stabilizes, which may result in erectile dysfunction or loss of penile length. Many urologists prefer to wait at least one year to surgically correct the curvature to help keep it from returning.

The progression of Peyronie's disease is not standard and will vary from patient to patient.
