Can Masturbation Cause Peyronie’s Disease?

No credible medical evidence links masturbation to the development of Peyronie’s disease. The condition involves the formation of fibrous scar tissue (called plaque) inside the tough outer sheath of the penis, and while trauma to that tissue is one proposed trigger, the kind of force involved in normal masturbation falls far short of what researchers believe is needed to start the process. What makes Peyronie’s disease develop in some men and not others appears to have far more to do with how their bodies handle wound repair at a cellular level than with any particular sexual activity.

Where the Worry Comes From

The idea that masturbation could cause Peyronie’s disease taps into a long history of unfounded medical claims about self-stimulation. For centuries, physicians blamed masturbation for conditions ranging from blindness to mental illness, and while modern medicine has thoroughly discredited those assertions, a residual anxiety persists in popular culture. When a man notices a new curve, lump, or pain in his penis, it is natural to search for a cause in recent behavior. Masturbation, being both common and private, becomes an easy suspect.

The worry gets reinforced by a real but often misunderstood piece of the Peyronie’s puzzle: the role of penile trauma. The current academic consensus does consider repetitive microvascular trauma or direct injury to the tunica albuginea a factor in the disease’s development.¹ Hearing “trauma causes Peyronie’s” and then applying it to vigorous masturbation feels like a logical step. But the leap from “trauma may play a role” to “masturbation is a cause” skips over critical details about what kind of trauma matters, and whether trauma alone is even sufficient.

The Trauma Hypothesis and Its Limits

The tunica albuginea is the dense, fibrous casing that surrounds the erectile chambers of the penis. It is remarkably tough tissue, with a complex structure of interlacing collagen fibers that gives it both strength and some flexibility.¹ The prevailing theory of Peyronie’s disease holds that when this tissue is injured, some men heal abnormally: instead of the wound resolving cleanly, excess collagen and fibrous tissue accumulate, forming a plaque that can pull the penis into a curve.

The types of trauma researchers have studied are considerably more forceful than anything that occurs during typical masturbation. One well-known study looked at two forms of significant penile injury: actual penile fracture (a rare but severe rupture of the tunica during erect intercourse) and a traditional practice called taqaandan, which involves deliberately bending the erect penis to make it go flaccid. Both of these involve forces that dramatically exceed what masturbation produces. Yet the study found that neither acute trauma from penile fracture nor chronic buckling injury from taqaandan was associated with later development of Peyronie’s disease.² The researchers concluded that this finding questions whether trauma and the inflammatory cascade it triggers are really the main causes of Peyronie’s disease.

This is an important result for the masturbation question. If even penile fracture, one of the most violent injuries the penis can sustain, does not reliably lead to Peyronie’s disease, then the much milder mechanical stress of masturbation is unlikely to be a meaningful trigger on its own.

Why Wound Healing Goes Wrong

If trauma alone does not explain Peyronie’s disease, what does? The evidence increasingly points to an underlying problem with how certain men’s bodies conduct tissue repair. Peyronie’s disease is now understood as a chronically impaired, localized wound-healing process within the tunica albuginea.³ In normal healing, the body lays down collagen to close a wound and then remodels it over time. In Peyronie’s, that remodeling fails, and fibrosis takes hold instead.

A key player is a signaling molecule called TGF-β1. Research comparing tissue from men with Peyronie’s disease to tissue from unaffected men has found that TGF-β1 is expressed at high levels in the overwhelming majority of Peyronie’s plaques.⁴ The cells in affected tissue also show heightened activity of internal signaling pathways that drive fibrosis, meaning these cells are essentially pre-wired to overreact to injury. Fibroblasts from men with Peyronie’s disease respond faster and more aggressively to TGF-β signals than fibroblasts from men without the condition.⁵

This means that the real vulnerability is biological, not behavioral. Two men can experience the same minor penile stress, whether from intercourse, masturbation, or even just an awkward movement during sleep, and one develops plaque while the other’s tissue heals without incident. The difference lies in their cellular machinery, not in what they did.

Risk Factors That Actually Matter

If you are looking for the things that genuinely increase the likelihood of Peyronie’s disease, the evidence points toward metabolic conditions, age, and a genetic tendency toward fibrotic disorders rather than any particular sexual behavior.

Diabetes stands out as one of the most consistent risk factors. The prevalence of Peyronie’s disease among men with diabetes and sexual dysfunction is roughly 11%, and poorly controlled blood sugar makes the association stronger.⁶ Men with the highest blood-sugar levels (measured by HbA1c above 8.5) have significantly elevated odds of developing the condition.⁷ Diabetes also appears to produce more severe disease: diabetic men with Peyronie’s are more likely to present in the chronic phase and to have curvature exceeding 60 degrees.⁶ It also seems to affect how well treatments work.⁸

Another telling clue is the overlap with Dupuytren’s disease, a fibrotic condition of the hand where cords of scar tissue form in the palm, gradually pulling the fingers into a bent position. In one cohort, about 13% of men diagnosed with Dupuytren’s also had Peyronie’s disease, while nearly 30% of men with Peyronie’s had Dupuytren’s.⁹ A separate study found that about 22% of men with Dupuytren’s had concomitant Peyronie’s, and bilateral Dupuytren’s (affecting both hands) was far more common in the group that also had penile plaque.¹⁰ A third fibrotic condition, Ledderhose disease (which affects the sole of the foot), was also significantly more common when both Peyronie’s and Dupuytren’s were present.⁹

This clustering of fibrotic conditions in the same patients strongly suggests a shared genetic or systemic predisposition. Nobody blames hand use for Dupuytren’s disease, and the parallel with Peyronie’s disease undercuts the idea that penile activity is the driving cause.

Is It Peyronie’s or Just a Natural Curve?

Men who worry about masturbation causing Peyronie’s disease are often noticing their own anatomy for the first time and wondering whether what they see is normal. It is worth knowing that some degree of penile curvature is extremely common and has nothing to do with Peyronie’s disease or any other condition. Congenital curvature is present from birth (or at least from the onset of erections in puberty) and results from slight asymmetries in the development of the erectile tissue. It does not involve plaque, does not progress, and does not cause pain.

The two conditions look quite different on closer examination. Congenital curvature tends to show up in younger men, with an average age of about 26 at the time of surgical consultation, whereas acquired curvature from Peyronie’s disease typically presents at an average age in the mid-50s.¹¹ Peyronie’s disease also tends to produce a sharper bend: the average curvature in one surgical series was about 63 degrees for Peyronie’s compared to about 48 degrees for congenital curvature.¹¹ Crucially, Peyronie’s disease usually comes with a palpable lump or plaque, and often with pain during the early phase. A curve you have had since your teens that has never changed and never hurt is almost certainly not Peyronie’s.

How Peyronie’s Disease Progresses

Peyronie’s disease generally moves through two phases. During the acute phase, which can last anywhere from several months to about 18 months, the plaque is actively forming. This is when men typically notice pain during erection, a worsening curve, or both. The chronic phase follows, during which pain usually resolves and the curvature stabilizes.¹² The distinction matters for treatment decisions, because most interventions are timed around disease stability.

If you are in the early stages and worried that continued masturbation will make things worse, the honest answer is that there is no evidence for that either. The forces involved in masturbation are not meaningfully different from those involved in vaginal or anal intercourse, and no medical guideline advises abstaining from sexual activity to prevent Peyronie’s progression. What does matter is avoiding genuinely traumatic events, like forceful bending of an erect penis, which is not a feature of normal masturbation.

The Psychological Toll

Perhaps the most underappreciated aspect of Peyronie’s disease is the psychological damage it inflicts. Men with the condition face significantly elevated rates of depression, anxiety, and self-injurious behaviors. A Swedish cohort study of 3.5 million men found that those with Peyronie’s disease had roughly double the risk of anxiety and self-injurious behaviors, and about 70% higher risk of depression compared to men without the condition.¹³ The prevalence of depression among men with Peyronie’s ranges from 12% to 62% across studies, and anxiety from 7% to 75%, depending on how and when it is measured.¹⁴

The sources of this distress go beyond physical symptoms. Loss of sexual confidence, feeling less attractive, performance anxiety, altered body image, and a sense of isolation all contribute.¹⁵ The shame and secrecy around penile conditions, including the very reluctance to bring them up with a doctor, can amplify these feelings. Unfounded guilt about masturbation having “caused” the condition adds another unnecessary layer of psychological burden. If you are dealing with Peyronie’s disease, recognizing that you did not bring it on yourself through normal sexual behavior is not just technically correct but genuinely important for your mental health.

How Peyronie’s Disease Is Diagnosed

Diagnosis typically begins with a physical exam where a clinician feels for plaque along the shaft. Ultrasound is the primary imaging tool because it can identify smaller and non-palpable lesions that a manual exam might miss, and it can show both calcified and softer fibrotic elements of the plaque.¹⁶ Ultrasound also helps evaluate erectile function by measuring blood flow, which provides useful information for planning treatment.¹⁷ If you are uncertain whether what you are feeling is a plaque or just normal anatomy, a urologist can typically resolve the question quickly.

Treatment Options

Treatment for Peyronie’s disease depends on the phase of the disease, the severity of the curvature, and whether erectile function is affected. In the acute phase, many clinicians recommend a watch-and-wait approach, sometimes supplemented with penile traction therapy to counteract shortening and slow the progression of curvature.

Traction therapy has the most evidence behind it as a conservative option. In clinical trials, men using a purpose-built traction device for as little as 15 minutes a day for six months experienced length gains of roughly two centimeters and curvature improvements of about 17 to 21 degrees.¹⁸ When combined with collagenase injections (the enzyme-based medication that breaks down plaque), the results were even more pronounced: one trial reported nearly 50% curvature improvement and significant length gains in the combination group, which outperformed either treatment alone.¹⁹

Surgery is reserved for men whose disease has stabilized and whose curvature or erectile dysfunction is severe enough to impair function. The surgical approach depends on the specific situation:

• Plication: The surgeon shortens the longer side of the penis to straighten it. This is the simplest procedure and is generally recommended for curves under about 60 to 70 degrees in men with good erectile function, though it does result in some loss of length.²⁰²¹
• Plaque incision and grafting: For more severe curvatures, hourglass deformity, or cases where the man wants to preserve length, the surgeon cuts into or partially removes the plaque and patches the gap with a graft. This is preferred for curvatures above 60 degrees or when the defect after incision would be larger than about two centimeters.²²
• Penile prosthesis: For men who have both significant curvature and erectile dysfunction that does not respond to medication, an inflatable prosthesis can address both problems at once.²¹

The Fibrotic Overlap With Other Conditions

The connection between Peyronie’s disease and other fibrotic disorders deserves more attention than it typically gets, because it reshapes how you think about causation. Dupuytren’s disease involves the same kind of runaway collagen production, just in a different anatomical location. Ledderhose disease does the same thing in the foot. When researchers find that roughly one in five men with both Peyronie’s and Dupuytren’s also have Ledderhose disease, the pattern starts to look systemic rather than local.⁹

This framing matters for anyone anxiously combing the internet for a behavioral explanation for their Peyronie’s disease. The condition is not a punishment for how you used your body. It is a manifestation of how your connective tissue responds to ordinary wear and repair, influenced by genetics, metabolic health, and the aging process. Masturbation, intercourse, and other routine sexual activity are part of the normal mechanical environment the penis is built for. If Peyronie’s disease develops, the vulnerability was already there. The trigger, if trauma played a role at all, could have been almost anything, and the same outcome might have occurred regardless. Spending energy on guilt over a normal activity adds psychological harm on top of a condition that already carries a significant emotional burden.
