- Peyronie's disease is a fibrotic disorder in which a plaque in the tunica albuginea causes penile curvature, indentation, or shortening, often with erectile dysfunction.
- It progresses through an acute (active) phase of pain and changing curvature and a chronic (stable) phase — treatment choices depend on which phase you're in.
- Diagnosis is clinical, usually confirmed with penile duplex ultrasound; a urologist is the right specialist.
- Collagenase (Xiaflex/CCH) is the only FDA-approved drug and can reduce curvature in stable-phase men with 30-90° curvature; surgery is reserved for severe, stable deformity.
- Costs are substantial and coverage varies, but many commercially insured patients pay little out of pocket through manufacturer support — verify your own coverage.
- This is general education, not medical advice — early urology referral matters, and online supplements are not a substitute for evaluation.

For decades treated as a quirky urologic curiosity, Peyronie’s disease is now recognized as a common, distressing fibrotic disorder. Population-based studies suggest a prevalence between roughly 3 and 9% of adult men, with higher rates in men with diabetes, prior pelvic surgery, or a family history. The AUA Peyronie’s Disease Guideline emphasizes that many men go years before bringing the issue up with a clinician — partly out of embarrassment, partly because they assume the curvature is permanent and untreatable. Neither assumption is correct. This article is general education, not medical advice.
What Peyronie’s Disease Is
Peyronie’s is a localized fibrosis of the tunica albuginea — the dense connective tissue sheath surrounding the corpora cavernosa. A fibrous plaque forms, typically dorsally, and prevents the affected segment of the tunica from expanding evenly during erection. The result is a curvature, an indentation, or shortening, often accompanied by erectile dysfunction.
The disease classically progresses through two phases. The acute (active) phase, lasting roughly 6 to 18 months, features pain with erection and changing deformity. The chronic (stable) phase begins when pain resolves and curvature stops progressing, usually around 12 months from onset. The distinction matters because treatment recommendations differ for each phase.
What Causes Peyronie’s
The leading theory is repeated microtrauma during intercourse, with abnormal wound healing in genetically susceptible men. The injury triggers an inflammatory cascade, fibroblast activation, and excess collagen and fibrin deposition that fails to remodel normally. Cleveland Clinic notes that men with Dupuytren’s contracture (palmar fibrosis) have a substantially higher risk, supporting a shared connective-tissue susceptibility.
Risk factors include diabetes, hypertension, dyslipidemia, low testosterone, age (peak incidence 50 to 60), pelvic surgery (notably radical prostatectomy), and tobacco use. Erectile dysfunction coexists in roughly half of cases — and the cause-and-effect relationship can run in both directions.
Symptoms
The classic presentation is a new, palpable plaque on the penile shaft along with progressive curvature noted during erection. Pain with erection is common during the active phase. Other manifestations include hourglass deformity, indentation, shortening, hinging, and erectile dysfunction. The curvature can be dorsal, ventral, lateral, or complex; severity ranges from cosmetic concern to inability to have penetrative intercourse.
Psychological impact is substantial. Multiple studies report depression and relationship distress in 50 to 80% of men with Peyronie’s. Symptom severity does not always track with anatomic severity — some men with mild curvature are devastated, and some with significant deformity adapt well.
How Peyronie’s Is Diagnosed
Diagnosis is clinical. A urologist takes a focused history covering onset, progression, sexual function, pain, and any inciting trauma. Physical exam during the flaccid state identifies the plaque; an in-office injection-induced erection or patient-supplied erect photographs document the curvature angle and shape. Penile duplex ultrasound is the reference standard for measuring plaque size, location, and calcification, and for assessing penile blood flow. The Mayo Clinic uses ultrasound routinely before any procedural intervention.
Treatment Options
Management depends on phase and severity, and it should be directed by a urologist. In the acute phase, treatment focuses on pain control and limiting progression. Oral therapies — pentoxifylline, vitamin E, L-carnitine, colchicine — have been used for decades but have weak evidence; the AUA Guideline does not recommend them as standard therapy. NSAIDs and traction therapy with FDA-cleared devices (such as RestoreX or PMP) have modest evidence for reducing curvature when used consistently over months, typically for a set period each day as directed by a clinician.
The most significant treatment advance is collagenase clostridium histolyticum (Xiaflex, or CCH), the only FDA-approved drug for Peyronie’s. It is injected directly into the plaque in cycles, breaking down collagen and reducing curvature. In the pivotal IMPRESS trials, it produced roughly double the curvature improvement of placebo — on average about a 17-degree reduction, with a meaningful improvement in bother score. It is approved for men with a palpable plaque and a curvature of 30 to 90 degrees in the stable phase, and the AUA gives it a moderate recommendation in that setting when combined with clinician- and patient-directed modeling. Costs are substantial: as of 2025, each injection of Xiaflex runs on the order of several thousand dollars plus an administration fee (roughly $6,800 per dose, plus about $350 to administer), and a full course can involve up to eight injections, so the list-price total can exceed those of many procedures. That said, coverage varies widely and many commercially insured patients pay little or nothing out of pocket through the manufacturer’s copay support — so verify your specific benefits before assuming a large bill. Intralesional verapamil and interferon alpha-2b are off-label injection alternatives with less robust evidence but lower cost.
Surgical correction is reserved for men in the stable phase with significant curvature, severe deformity, or coexisting ED unresponsive to medical therapy. Options include plication procedures (suturing the convex side to straighten — shortens the penis but spares erections), plaque incision and grafting (preserves length but carries higher ED risk), and penile implant with concurrent straightening (often considered the best option for men with both Peyronie’s and refractory ED). Reported satisfaction rates are commonly 70 to 90% across procedures in experienced hands.
When to See a Doctor
Any new penile pain, palpable lump, or curvature deserves evaluation, especially if it is progressing. Early referral during the acute phase opens up options like traction and CCH that work best when started early or in the stable phase before extreme deformity sets in. Men whose curvature prevents intercourse, whose ED is worsening, or who are experiencing significant emotional distress should not wait. Sexual partners are often part of the conversation, and many urologists welcome partner involvement.

Frequently Asked Questions
Will Peyronie’s disease go away on its own?
Only a minority of men — on the order of 12 to 13% — experience spontaneous improvement; roughly half stay the same, and the rest worsen without treatment. Counting on spontaneous resolution is not generally a good strategy, particularly when curvature is interfering with intercourse.
Does Xiaflex really work?
Yes, but the effect size is moderate. Pivotal trials showed an average curvature reduction of about 17 degrees and a meaningful improvement in patient-reported bother. It is most useful for men with curvatures between 30 and 90 degrees and intact erections. Men with severe deformity, hourglass plaques, or coexisting ED may benefit more from surgery. Your urologist can advise whether you are a candidate.
Can Peyronie’s cause infertility?
Indirectly. Severe curvature can prevent intromission and intercourse, which obviously interferes with conception. Peyronie’s does not affect sperm production. Workarounds include intrauterine insemination if the curvature is the only barrier.
Are penile pumps helpful?
Vacuum erection devices are sometimes used as adjunctive therapy to help maintain length and preserve erectile function. Evidence for curvature reduction on their own is limited, and they are commonly combined with traction therapy in stable-phase patients under a clinician’s guidance.
How much does Peyronie’s treatment cost?
It varies widely by treatment and insurance. Traction devices are a few hundred dollars; Xiaflex has a high list price (thousands of dollars per injection across a multi-injection course), but many commercially insured men pay little through copay support. Surgery costs depend on the procedure and facility. Confirm coverage and out-of-pocket estimates with your urologist and insurer before starting.
The Bottom Line
Peyronie’s disease is more treatable now than it has ever been. Early urology referral, accurate phase classification, and matching the therapy to the deformity produce real outcomes — preserved sexual function in most men and effective surgical correction in those who need it. Avoidance and online supplements waste the window when treatment works best, so an evaluation is the practical first step.
