The most common cause of Peyronie’s Disease is from strenuous sex where the penis is bent during penetration. Other causes include accidents or sports activity. In many cases, no specific injury is recalled which makes the exact cause of Peyronie’s Disease difficult to determine.
There are other factors health experts believe may play a role in the cause of Peyronie’s Disease. These include age (most prevalent in men over 40), heredity and some form of connective tissue disorder. Men who have PD also have an increased risk Dupuytren’s contracture which is a gradual thickening of tissue under the skin of the hand/palm. As this tissue thickens, it feels like a rope or hard cord that causes the fingers to stay bent inward.
