There’s no guaranteed way to prevent Peyronie’s disease, but you can significantly lower your risk by addressing the factors that cause it: repetitive micro-trauma to the penis, chronic inflammation, and poor vascular health. The condition affects roughly 10% of men at some point, most commonly between ages 40 and 59, though about 22% of cases occur in men under 40.
How Peyronie’s Disease Develops
Understanding what causes Peyronie’s disease is the first step toward preventing it. The widely accepted explanation is that small, repeated injuries to the penis during sex or physical activity create tiny tears in the tough tissue layer that surrounds the erectile chambers. These micro-tears trigger an inflammatory response: blood leaks into the damaged area, immune cells flood in, and the body begins laying down scar tissue as a repair mechanism.
In most people, this healing process resolves normally. But in some men, the process goes haywire. Certain cells convert into a type that produces excessive collagen and fibrous tissue. This buildup forms the hard plaques that define Peyronie’s disease, eventually causing curvature, shortening, pain, or erectile problems. The key insight for prevention is that this chain of events has two entry points you can influence: reducing the initial trauma and keeping inflammation in check so your body heals normally.
Reduce Penile Trauma During Sex
Sexual activity is the most common source of the micro-injuries that start the fibrotic process. This doesn’t mean sex is dangerous, but certain situations carry more risk. Vigorous thrusting, positions where the penis is more likely to bend or buckle against a partner’s body, and intercourse without sufficient lubrication all increase the chance of those small internal tears.
Practical steps to lower this risk:
- Use adequate lubrication. This reduces friction and the force transmitted to penile tissue during penetration.
- Avoid positions with high buckling risk. Positions where your partner is on top carry a higher chance of the penis bending sharply if it slips out or meets resistance at the wrong angle. Being mindful during these positions, rather than avoiding them entirely, is a reasonable approach.
- Don’t force penetration. If the penis isn’t fully erect, attempting intercourse increases the likelihood of it bending or folding in ways that damage the internal tissue layers.
Quit Smoking
Smoking is an independent risk factor for Peyronie’s disease, meaning it can promote the condition on its own without any other triggers present. Tobacco combustion releases toxic compounds that cause chronic inflammation in penile tissue. Over time, this persistent low-grade inflammation can generate or worsen the fibrosis that forms Peyronie’s plaques.
Smoking also damages blood vessels in two ways that compound the problem. It causes vasoconstriction (narrowing of blood vessels) and impairs the inner lining of those vessels. The result is reduced blood flow to the penis, which weakens erections and creates an environment where fibrous plaques form more easily. Research shows significant associations between Peyronie’s disease and both the duration of smoking and the number of cigarettes smoked per day. If you smoke, quitting is one of the most direct prevention steps you can take.
Manage Diabetes and Cardiovascular Risk
Diabetes is one of the strongest medical risk factors for Peyronie’s disease. Men who have had diabetes for more than 10 years are six times as likely to develop the condition compared to those with diabetes for fewer than five years. And nearly 96% of diabetic men diagnosed with Peyronie’s disease had poor blood sugar control.
The connection makes biological sense. Poorly controlled diabetes accelerates vascular damage and nerve complications throughout the body, including the penis. It promotes the kind of chronic inflammation that drives abnormal scar tissue formation. If you have diabetes, keeping your blood sugar well managed is one of the most effective things you can do to reduce your Peyronie’s risk.
Other cardiovascular risk factors also show significant associations with the disease. Obesity, high cholesterol, and high blood pressure all contribute to the same vascular dysfunction and inflammatory environment that promotes plaque formation. Maintaining a healthy weight, staying physically active, and managing cholesterol and blood pressure aren’t just good for your heart. They protect the small blood vessels in the penis that are vulnerable to the fibrotic process.
Wear Protection During Contact Sports
While sexual micro-trauma gets the most attention, direct impact injuries to the groin during sports can also damage penile tissue. Lacrosse, wrestling, baseball, and football carry the highest rates of genital injury. An athletic cup provides the most complete protection and is recommended for any contact sport or activity where groin impact is possible. Compression shorts or a jockstrap offer less protection but are better than nothing for sports like running, basketball, or skating where jostling is an issue.
Know Your Personal Risk Level
Some men are more susceptible to Peyronie’s disease than others. The condition clusters in families, suggesting a genetic component in how the body handles tissue repair and inflammation. If you have a close relative with Peyronie’s disease, or if you have another connective tissue condition like Dupuytren’s contracture (thickening in the palm of the hand), your body may be more prone to abnormal scarring. This doesn’t mean the disease is inevitable, but it does mean the prevention strategies above carry extra weight for you.
Age also matters. The majority of cases appear between 40 and 59, a period when vascular health tends to decline and the body’s repair mechanisms become less efficient. Men in this age range benefit most from proactively addressing cardiovascular risk factors and being attentive to early warning signs.
Recognize Early Signs Before Progression
Prevention also means catching the disease early if it does develop. The acute (active) phase is when intervention has the best chance of limiting damage. Early signs include:
- A small lump or hard area felt under the skin of the penis, sometimes with tenderness over it
- New curvature during erections, whether upward, downward, or to one side
- Pain during erections or intercourse that wasn’t there before
- Erectile difficulty that appears before other symptoms (this is actually a common early signal)
Many men notice erectile dysfunction before they notice curvature or a palpable plaque. If you develop new erection problems alongside any penile tenderness or changes in shape, that combination warrants prompt evaluation. During the early active phase, the plaque is still forming and the disease hasn’t stabilized, which means early treatment has the best chance of preventing further curvature or shortening. Waiting until the disease has fully matured limits your options.
