Peyronie’s Disease Treatment: Does Penile Curvature Fix Itself? When Surgery Is Needed

Waking up to a bent, painful erection is a shock. For many men, Peyronie’s disease starts silently: a small lump under the skin of the shaft, an ache during erection, then a curvature that appears and worsens over weeks. Some hope it will fade on its own. It almost never does.

Peyronie’s disease affects roughly 3–9% of adult men, with real prevalence probably higher because most men are too embarrassed to seek help until sex becomes impossible. This guide, written from more than a decade of andrological practice in Istanbul, explains the two phases of the disease, which non-surgical treatments actually work, and the exact clinical thresholds that push a urologist to recommend surgery.

What is Peyronie’s disease?

Peyronie’s disease is the formation of fibrous scar tissue — called plaque — inside the tunica albuginea, the thick sheath surrounding the erectile chambers of the penis. When the penis fills with blood, the scarred segment cannot stretch as much as the healthy tissue around it. The result is curvature, indentation, hourglass narrowing, or shortening.

Anatomical length or girth is a separate procedure — details on our penis enlargement surgery page.

The most widely accepted trigger is repeated micro-trauma during intercourse in a genetically susceptible man. Risk factors include Dupuytren’s contracture of the hand, connective tissue disorders, diabetes, low testosterone, previous prostate surgery, and family history.

The two phases: acute vs chronic

Understanding which phase you are in is the single most important step, because it changes every treatment decision.

An office-based option worth mentioning is glans (penis head) filler for premature ejaculation.

Operating during the acute phase is a mistake — the deformity is still evolving, and any correction may be undone as the disease continues. Waiting for stability is not procrastination; it is the standard of care.

Does Peyronie’s disease heal by itself?

The honest data:

• Spontaneous improvement in curvature: about 12–13% of untreated men
• No change: about 40%
• Worsening: about 40–50%

Pain almost always resolves within 12–18 months on its own, but that is not the same as the disease resolving — the curvature usually remains and often progresses. “Wait and see” without any active management is only appropriate for men with minimal curvature (<20°), no pain, and preserved sexual function.

Watchful waiting — who and when

Reasonable candidates for observation alone:

A nerve-targeted alternative when medication fails is selective dorsal cryoablation for premature ejaculation.

• Curvature under 20 degrees
• No pain or pain fading month over month
• Intercourse still possible without difficulty for both partners
• No hourglass deformity or hinge effect
• Willing to return every three months for photographic reassessment

Even these men benefit from starting a low-risk traction protocol early — because the tissue is more responsive during the acute phase.

Oral therapy: what actually works

Oral treatments have modest and often disappointing effects, but a few are used because side effects are low and the acute-phase window is limited:

For an honest breakdown of what enlargement really delivers, see the penis enlargement truth.

• Pentoxifylline 400 mg × 3/day — anti-fibrotic; the best oral evidence, particularly for early plaques
• Vitamin E 400 IU/day — mixed evidence; largely obsolete as monotherapy, still used as adjunct
• L-carnitine, coenzyme Q10, colchicine — weak evidence; not recommended by EAU as monotherapy
• Tadalafil 5 mg daily — reduces smooth-muscle fibrosis and treats any coexisting ED (roughly 50% of Peyronie’s patients)

No oral drug has been shown to reliably reduce established curvature. Use them as part of a combined protocol, not a standalone cure.

Traction devices (RestoreX, Penimaster)

Mechanical traction is one of the few conservative treatments with genuine evidence of reducing curvature — but only if used properly.

• RestoreX (US-developed, Mayo Clinic trial data): 30–90 minutes daily; average curvature reduction 10–17 degrees, length gain 1.5 cm over 3 months
• Penimaster PRO (European): similar mechanism, comparable results with 4–8 hours daily use
• Andropenis: older design, still useful, tolerability lower

Traction works because collagen remodels under sustained tension. It works best in the acute phase and as an adjunct to injections. Compliance is the enemy — most men who fail traction did not use the device long enough.

Intralesional injections: Xiaflex & verapamil

Collagenase Clostridium histolyticum (Xiaflex) is the only FDA-approved non-surgical therapy for Peyronie’s. It enzymatically breaks down the collagen in the plaque. Standard protocol: 4 cycles, each with 2 injections plus modeling. Average curvature reduction: 34% (about 17 degrees).

For international pricing, read penile implant cost in Turkey.

Important: Xiaflex is licensed in the United States. It is not available in Turkey, and it was withdrawn from the European market in 2020. International patients seeking Xiaflex must travel to the US.

Verapamil intralesional injection is our workhorse alternative in Turkey and much of Europe. Ten milligrams diluted, injected directly into the plaque every two weeks for 12 sessions. Evidence quality is lower than Xiaflex, but properly delivered verapamil reduces curvature in roughly 50–60% of men, with a good safety profile and low cost.

Interferon-alpha-2b is another option with mid-level evidence, more inflammation post-injection, and higher cost. Rarely first-line in our clinic.

Shockwave therapy for Peyronie’s

Low-intensity extracorporeal shockwave therapy (LI-ESWT) is very useful for erectile dysfunction, but for Peyronie’s the evidence is much more limited. Current consensus (EAU 2024): shockwave reliably reduces pain in the acute phase but does not significantly straighten established curvature. We use it for painful acute disease as an adjunct, not as a standalone straightening treatment.

Surgery 1 — Plication (Nesbit & 16-dot)

Plication techniques shorten the side of the penis opposite the curve to straighten the shaft. The classic Nesbit procedure removes a small wedge of tunica; the modern 16-dot (Lue) technique uses non-absorbable sutures without tissue excision, preserving anatomy and length as much as possible.

A device-by-device breakdown is in our inflatable vs malleable penile implant guide.

Best candidate:

• Curvature under 60 degrees
• No hourglass or hinge deformity
• Adequate penile length (plication shortens by 0.5–1.5 cm)
• Good baseline erections

Straightening success: 85–95%. Recurrence: 5–10%. Palpable sutures possible but rarely troublesome. Return to sex: 6 weeks.

Surgery 2 — Plaque incision & grafting

For severe curvature (>60°), hourglass narrowing, or short penises where plication would shorten too much, the surgeon incises the plaque and patches the defect with a graft — usually bovine pericardium (Tutoplast), porcine small intestinal submucosa, or occasionally the patient’s own tissue.

Evidence-based, non-drug techniques are in our guide on how to last longer in bed.

Grafting preserves length and corrects complex deformity but carries a higher risk of postoperative ED (10–20%) because the surgery is closer to the neurovascular bundle. Careful patient selection — and thorough preoperative evaluation of erectile function including penile Doppler ultrasound — is essential.

Surgery 3 — Penile prosthesis with straightening

When Peyronie’s coexists with significant erectile dysfunction that does not respond to PDE5 inhibitors, the best single operation is a penile prosthesis (implant) combined with intraoperative straightening — usually manual modeling, or if needed, plication or a small graft during the same procedure.

This solves two problems in one operation:

• Reliable erection on demand
• Straight, functional penis

Modern three-piece inflatable prostheses have satisfaction rates above 90% in Peyronie’s patients — often higher than in the general ED population, because these men have suffered longer.

Recovery and outcome expectations

Nighttime traction with a RestoreX or Penimaster is often continued for 6–12 weeks after any Peyronie’s surgery to counteract postoperative scar contracture.

A complete comparison of sprays, pills, injections and surgery is in our premature ejaculation treatment guide.

Doctor’s perspective — Op. Dr. Cem İpek

The men who do worst are those who wait five years hoping the curve will go away. By the time they come to see me, the plaque is calcified, ED has taken hold, and half the reconstructive options are already off the table. Come in during the first year, even if all we do is start a traction protocol — the tissue is still plastic then.

Xiaflex works, but the noise around it in the English-speaking internet is out of proportion. In real numbers it reduces curvature by about a third — meaningful, but rarely enough for a 70-degree bend. Verapamil injection plus disciplined traction, done for the full 12-week protocol, gives outcomes very close to Xiaflex at a fraction of the cost, and it is available across Europe.

When curvature has been stable for a year and intercourse is impossible, surgery is not a luxury — it is the treatment. Modern plication for a simple 45-degree curve is a one-hour outpatient procedure with a return to sex in six weeks and a satisfaction rate above 90%. Delaying it does not preserve options; it narrows them.

When to see a urologist

Book an appointment if any of the following applies:

• Painful erection lasting more than four weeks
• A palpable lump or nodule under the penile skin
• New or worsening curvature, hourglass, or indentation
• Penis feels shorter than before
• Intercourse has become difficult or painful for either partner
• New erectile dysfunction alongside any of the above
• Family or personal history of Dupuytren’s contracture

Early evaluation almost always widens your treatment options — and lowers the chance that surgery will be the only remaining choice.
