How Common Is Peyronie’s Disease? Prevalence and Risk

Peyronie’s disease is more common than most people realize, though pinning down a single prevalence number is tricky. Estimates in the medical literature range from under 1% to nearly 12%, depending on how researchers define and screen for the condition. The best evidence suggests that somewhere between 3% and 9% of adult men are affected, with the true figure likely closer to the higher end because many cases go undiagnosed. Several modifiable and non-modifiable risk factors, from diabetes to genetics to prior surgery, meaningfully increase the odds.

Why Prevalence Estimates Span Such a Wide Range

The single biggest reason researchers disagree on how common Peyronie’s disease is comes down to how they look for it. Studies that rely on self-reported surveys tend to produce different numbers than studies where a urologist physically examines patients. A large U.S. population-based survey of over 7,700 men found that only about 0.7% met a strict “definitive” case definition, but when probable cases were included, the estimated prevalence jumped to 11.8%.¹ That gap between definitive and probable reflects the challenge: many men have penile curvature or palpable plaque but have never been formally diagnosed.

A review of the epidemiological literature put the figure at up to 9%, while noting that the data are inconsistent across studies and countries.² Some of the variation also comes from the populations studied. Surveys conducted in urology clinics naturally catch more cases than surveys of the general public, because men visiting a urologist already have a reason to be there. Embarrassment and stigma further suppress the numbers: men who have curvature or pain during erections often do not bring it up, even with their doctors. The condition is almost certainly underdiagnosed, especially among men with erectile difficulties who cannot achieve erections firm enough to reveal the full extent of deformity.³

Age, Race, and Other Demographic Patterns

Peyronie’s disease can show up at any age. The literature documents cases from teenagers to men in their seventies and eighties.² That said, most diagnoses cluster in men between their forties and sixties, which tracks with the accumulation of the micro-injuries and metabolic risk factors that drive plaque formation over time.

The U.S. population survey found an interesting wrinkle with age: younger respondents were actually somewhat more likely to fall into the probable or definitive category than older ones, with a modest decrease in odds for those in the 24-and-older age group compared to the youngest group surveyed.¹ This might reflect greater awareness among younger men or willingness to report symptoms, rather than a true biological trend toward younger onset. Geographic region and income also showed up as predictors in that study, though region was the stronger factor. Racial and ethnic data remain limited in most population-level surveys, though research in surgical populations (discussed below) has found significantly higher rates in white men compared to non-white men.

The Diabetes Connection

Diabetes is one of the most consistently identified risk factors for Peyronie’s disease, and the link appears to be dose-dependent. Men with diabetes are significantly more likely to develop the condition, and among those with diabetes, higher blood sugar levels make things worse. One study found that men with the poorest glucose control, defined as hemoglobin A1c above 8.5%, had about 60% higher odds of having Peyronie’s disease compared to men with better-controlled diabetes.⁴

The connection is not just about whether a man develops the disease but also how severe it gets. Research comparing men with Peyronie’s disease who had diabetes against those who did not found that the diabetic group had substantially worse curvature on average, around 45 degrees compared to 30 degrees. The rate of severe curvature above 60 degrees was roughly five times higher in the diabetic group, and those men also had poorer penile blood flow on vascular testing.⁵ The likely explanation is that diabetes promotes chronic inflammation and impairs normal wound healing throughout the body, and the penile tissue is no exception.

What Happens Inside the Tissue

At its core, Peyronie’s disease is a wound-healing problem. The tunica albuginea, the tough fibrous sheath that surrounds the erectile chambers, sustains small injuries, often from the normal mechanical stress of sexual activity. In most men these micro-tears heal normally. In men who develop Peyronie’s, the healing process goes off track. Chronic inflammation takes hold, and instead of resolving, the body lays down excess scar tissue in the form of a fibrous plaque.⁶

The abnormal scarring involves an imbalance in the enzymes that build up and break down connective tissue, combined with weakened antioxidant defenses. Certain signaling molecules, particularly TGF-beta, play a central role in driving cells to produce too much collagen and fibrous material.⁷ The result is a dense plaque that does not stretch the way normal tissue does, pulling the penis to one side during erection and sometimes causing pain. What makes some men vulnerable to this cascade while others heal normally involves genetics, anatomy, and metabolic health, all working together.⁸

Links to Other Fibrotic Conditions

One of the more telling clues about who is at risk comes from the overlap between Peyronie’s disease and Dupuytren’s contracture, a condition where fibrous tissue builds up in the palm and gradually curls the fingers inward. The two conditions share strikingly similar gene expression patterns, with both showing overactivity in gene families involved in collagen breakdown and scar-cell formation.⁹

The clinical overlap is substantial. A study at a tertiary andrology center found that about one in five men diagnosed with Dupuytren’s contracture also had Peyronie’s disease. Among those with both conditions, bilateral Dupuytren’s (affecting both hands) was a strong predictor, with dramatically elevated odds compared to unilateral disease.¹⁰ Looking from the other direction, a French cohort found that about 29% of men being followed for Peyronie’s disease also had Dupuytren’s.¹¹ If you have Dupuytren’s, or a family history of it, the odds that Peyronie’s could show up are meaningfully higher than average. Other fibrotic conditions like plantar fibromatosis (Ledderhose disease) are also reported to co-occur, though the evidence base is thinner.

Genetic Susceptibility

The fact that Peyronie’s disease runs in some families has been recognized for decades. Twin studies and family clustering reports have long suggested a heritable component, and molecular work over the past several years has started to identify specific genetic markers.¹² One genome-wide association study identified a variant near the WNT2 gene on chromosome 7 that was significantly associated with Peyronie’s disease. The association actually grew stronger when the researchers removed patients who also had Dupuytren’s contracture, suggesting that while the two diseases share some genetic ground, Peyronie’s also has its own distinct susceptibility pathways.¹³

Having a genetic predisposition does not mean the disease is inevitable. The current understanding is that genetics loads the gun, while environmental and metabolic factors pull the trigger. A man with the relevant genetic variants who never sustains penile micro-trauma or develops metabolic disease may never form a plaque. But that same genetic background makes his wound-healing system more likely to overreact when injury does occur.

Radical Prostatectomy and Surgical Risk

One of the most striking risk-factor findings in the Peyronie’s literature involves prostate surgery. Among over 1,000 men who underwent radical prostatectomy for prostate cancer, about 16% developed Peyronie’s disease afterward, with the average time to onset being roughly 14 months after surgery.¹⁴ That rate is far higher than the general population estimates discussed earlier.

The likely explanation involves the period of erectile dysfunction that commonly follows prostate removal. When the penis goes through weeks or months without normal erections, the tissue receives less oxygenation and blood flow, which can set the stage for fibrotic changes. Counterintuitively, the study found that younger age was actually a predictor of developing Peyronie’s after surgery, with the odds increasing by about 30% for every five-year decrease in age. White race was also a strong independent predictor, with roughly four times the odds compared to non-white men.¹⁵ The younger-age finding might reflect more aggressive attempts at sexual activity during recovery, or it may point to biological factors that remain poorly understood.

Trauma and Medications

Beyond surgery, direct penile trauma is considered a contributing factor. The plaques that characterize Peyronie’s disease reduce the elasticity of the tunica albuginea at specific points, and the resulting curvature concentrates mechanical stress during erections. This creates a feedback loop: existing disease increases vulnerability to further injury, including in rare cases penile fracture, which is a tearing of the tunica during sexual activity.¹⁶ Not every man with Peyronie’s will experience anything close to that extreme, but the principle holds: curvature changes the mechanics, and altered mechanics can worsen the disease.

Certain medications have also been flagged. Beta-blockers, a class of blood pressure and heart medications, have been associated with the onset and progression of Peyronie’s disease in case reports and pharmacological reviews.¹⁷ The mechanism is not fully worked out, but beta-blockers are known to affect connective tissue metabolism. This does not mean every man on a beta-blocker should panic. The association has been noted mainly through case reports and observational data rather than large controlled studies. Still, if you notice changes in penile curvature after starting a beta-blocker, it is worth mentioning to your doctor.

The Relationship With Erectile Dysfunction

Peyronie’s disease and erectile dysfunction frequently travel together, and the relationship runs in both directions. In a study of men seeking treatment for erectile dysfunction, about 8% were found to have Peyronie’s disease, and the condition was more common in men whose erectile problems were longer-lasting and more severe.¹⁸ Coming at it from the other side, research in men already diagnosed with Peyronie’s found that most had some degree of erectile difficulty, with mild-to-moderate dysfunction being the most common pattern.¹⁹

One older but widely cited study put numbers on the timeline. Among 176 men with Peyronie’s disease, about 40% reported decreased erectile rigidity even before their Peyronie’s began, while roughly 59% noticed their erections worsening after the disease appeared.²⁰ In other words, the two conditions feed off each other: the plaque can physically impair the vascular mechanics of erection, while poor erectile function may reduce tissue oxygenation and promote further fibrosis. For men dealing with both, treatment often needs to address the erectile component alongside the curvature.

How the Disease Progresses Over Time

Peyronie’s disease typically moves through two phases. The early or “acute” phase involves active inflammation, plaque formation, and often pain during erections. This phase can last anywhere from several months to about a year and a half. After that, things tend to settle into a “chronic” or stable phase where pain resolves but the curvature remains more or less fixed.²¹

A natural history study tracked men over time and found that pain almost always improved, with 89% reporting complete resolution at follow-up. Curvature, however, was a different story. About 12% of men saw their curvature improve on its own, 40% remained stable, and 48% got worse. Among those who worsened, the average increase was 22 degrees. Among those who improved, the average decrease was 15 degrees.²² The takeaway is that spontaneous improvement does happen, but it is the minority outcome. Waiting and hoping things resolve on their own is a gamble that works less than half the time.

The Psychological Burden

The emotional toll of Peyronie’s disease is considerable and probably underappreciated by the medical community. Research estimates that around half of men with the condition experience depressive symptoms, and upwards of 80% report significant distress related to it.³ This goes beyond the physical symptoms. Men describe shame, a damaged sense of masculinity, relationship strain, and avoidance of sexual intimacy altogether.

A large Swedish cohort study of 3.5 million men put harder numbers on the psychiatric associations. Men diagnosed with Peyronie’s disease had roughly 1.9 times the risk of being diagnosed with an anxiety disorder and 1.7 times the risk of depression compared to men without the condition. The risk of self-injurious behavior was doubled. Even after accounting for other factors, the overall risk of any psychiatric outcome was about 40% higher.²³ These are not small effect sizes. They suggest that Peyronie’s disease does real psychological damage, and that mental health screening should be a standard part of care for men with this diagnosis. Partners are affected too: studies consistently note that relationship distress is a major theme in the psychological literature on Peyronie’s, though the partner’s perspective remains understudied.

When Men With Dupuytren’s Should Pay Attention

For men who already have Dupuytren’s contracture, the data on overlap deserves a closer look beyond just the headline co-occurrence rates. In the tertiary-center study, bilateral Dupuytren’s was an especially powerful predictor of also having Peyronie’s disease, with an odds ratio above 17 in the final statistical model. Diabetes compounded the risk further: among men with both Dupuytren’s and Peyronie’s, over 80% also had diabetes, compared to about 44% in the Dupuytren’s-only group.¹⁰

The practical implication is straightforward. If you have Dupuytren’s contracture, especially in both hands, and you also have diabetes, you belong to a demographic where Peyronie’s disease is not rare at all. It may be worth raising the topic with a urologist proactively, rather than waiting for symptoms to become obvious. Screening in this population does not require anything invasive; a physical exam and a conversation about any changes in penile shape or pain during erections can catch the problem early, when treatment options are broadest.
