Only a small fraction of cases of Peyronie’s disease occur after there has been a clear, noticeable injury to the penis. The remaining cases are thought to be caused by small injuries and inflammation that has occurred over a long period of time. Because of this, the major risk factors for Peyronie’s disease are injury, age, smoking, and health conditions associated with inflammation and scarring.
Common Causes
Peyronie’s disease is first and foremost a wound-healing disorder. Its symptoms are the result of fibrous plaques, or scars, forming in the tunica albuginea. The tunica albuginea is the tissue that surrounds the erectile bodies of the penis.
Peyronie’s disease is thought to occur in between 0.5%and 20%of men, depending on the population. It can happen in men of any age, but it is more common in older men. It is also more common in individuals suffering from one or more of the following health problems:
Diabetes High blood pressure High cholesterol
Smoking is another significant risk factor for Peyronie’s disease.
Peyronie’s is thought to be the result of injury to the penis. This injury can be severe and acute, for example, because of surgery on the penis or trauma during sex.
More often, the injuries that lead to Peyronie’s are small, or even unnoticeable. Most, if not all, men experience some microtrauma during penetrative intercourse. However, only some men develop Peyronie’s disease. This is likely because Peyronie’s disease occurs in men where healing is impaired.
Having sex with a penis that is not fully erect may predispose the penis to microtrauma. This may also explain why the incidence of Peyronie’s disease increases with age. As people have more difficulty getting a firm erection, they experience more sub-acute injuries they need to heal.
Cardiovascular Health
High blood pressure, high cholesterol, and diabetes are all associated with both cardiovascular health and Peyronie’s disease. So is the use of certain cardiovascular drugs, such as beta-blockers. This is thought to be because the particular vasculature of the penis, and damage to those blood vessels, is critical to the formation of plaques and scars. There is also some evidence that oxidative stress plays a role in Peyronie’s disease as well as heart disease.
In addition to potentially playing a direct role in causing Peyronie’s disease, cardiovascular disease also contributes significantly to one of its symptoms.
Scarring compounded with poor blood flow contributes to the symptoms of Peyronie’s. Improved blood flow is thought to help healing. This is why Viagra and other erectile dysfunction drugs may be useful for Peyronie’s patients.
Lifestyle Risk Factors
There are a number of lifestyle risk factors for Peyronie’s disease. Basically, these can be divided into two groups. The first group are risk factors that affect healing. These include:
Smoking Alcohol abuse A history of unprotected sex leading to non-gonoccocal urethritis or exposure to another inflammatory STD
The other group of risk factors are those that affect the likelihood of penile trauma. These include:
Rough sex or sex at angles that bend or stretch the penis. Starting penetration before the penis is fully erectOther activities that could damage the penis.
A Word From Verywell
To a great extent, Peyronie’s disease is not a condition you can avoid. You can maintain a healthy body, but inflammation and penile injury are not necessarily things you can control.
Fortunately, Peyronie’s disease is often a relatively minor condition. Many individuals affected by it do not need any treatment. There is a range of treatments available for those who do.
If you are experiencing pain during erection, or noticing a new curve to your penis, talk to your healthcare provider. If it is Peyronie’s disease, sometimes early treatment can help.
