How does Peyronie’s disease develop?

Although the exact cause of Peyronie’s disease is not known, current scientific research indicates that an exaggerated healing process in the body occurs after trauma to the penis, which may happen during intercourse. It is important to note that the vast majority of patients will not recall a specific traumatic intercourse event and that the “trauma” may not be very different from what is normally experienced.

In Peyronie’s disease, this exaggerated response leads to tunical (the lining of the penis) plaque formation. As a result of this plaque (not the same as blood vessel or heart plaques), the penis tends to be deformed or curved when erect. The plaque may also affect the quality of erections, so a person suffering from Peyronie’s disease may experience both poor erections and a deformed or curved penis.

Pain in the plaque area is not always a symptom of Peyronie’s disease, but it certainly can be an additional burden for many men. When pain is observed, it is usually in the first 12 to 18 months, when the pathology is thought to be in its active phase (when the plaque may be going through changes that can affect the shape of the penis). In some cases, the degree of curvature is such that intercourse may be impossible due to discomfort for the patient or his partner.
