Peyronie's disease: curvature, pain, and what actually treats it
There is one FDA-approved drug for Peyronie's and a large market of things that are not. Knowing which phase you are in determines what you should do — and what you should refuse.

Peyronie's disease is fibrous scar tissue — a plaque — forming in the tunica albuginea, the tough sheath surrounding the erectile bodies. Scar tissue does not stretch the way healthy tissue does, so when the penis fills with blood it bends toward the plaque.
It causes curvature, sometimes pain, often shortening, and frequently erectile dysfunction on top. It is also poorly served by the internet, which is full of devices and supplements sold against a condition that has exactly one approved drug.
The two phases, and why they change everything
Nearly every treatment decision depends on which phase you are in. Get this wrong and you will either be operated on too early or treated too late.
| Acute (active) phase | Chronic (stable) phase | |
|---|---|---|
| Typically lasts | Roughly 6–18 months | Indefinitely, once reached |
| Pain | Common, often with erections | Usually resolved |
| Curvature | Changing — may worsen month to month | Stable for several months |
| What is appropriate | Symptom management; documenting the change | Injections or surgery can be considered |
| What is not | Surgery — the curve is still moving | Waiting indefinitely to see if it improves |
The one approved drug
Xiaflex — collagenase clostridium histolyticum — is the only FDA-approved drug treatment for Peyronie's disease. It is an enzyme injected directly into the plaque to break down the collagen it is made of, given in a series of cycles alongside modelling of the penis by the clinician and by you.
| What the label and guidance say | |
|---|---|
| Approved for | Palpable plaque with curvature of 30° or more |
| AUA guidance | May be used in stable disease with curvature over 30° and under 90°, with intact erectile function |
| Typical benefit | Mean curvature improvement reported in the region of 29–34% |
| Not studied in | Hourglass deformity, ventral curvature, calcified plaque, or plaque at the base |
What the evidence says about everything else
This is where a lot of money gets spent on very little.
| Treatment | Where it stands |
|---|---|
| Intralesional verapamil | May be offered, but on a weak recommendation — efficacy is inferior to collagenase and study findings conflict |
| Electromotive verapamil | Specifically not recommended in AUA guidance |
| Traction therapy | Some supporting evidence, but it demands many hours a day over months. Adherence is the limiting factor, not plausibility |
| Oral vitamin E, colchicine, pentoxifylline | Widely sold and weakly supported. Guidance does not endorse them for curvature |
| Shockwave therapy | May help with pain in the active phase. It does not correct curvature — see our shockwave review |
| Supplements marketed for Peyronie's | No approved product, no reliable evidence — see herbal ED supplements |
Surgery, once the disease is stable
Surgery is the most reliable way to correct curvature, and the choice among approaches turns largely on your length and whether you also have erectile dysfunction.
- Plication — shortens the longer, unaffected side to match. Simple and reliable, at the cost of some length. Usually suited to less severe curves in men with good length.
- Plaque incision or excision with grafting — lengthens the affected side instead. Preserves more length, but carries a higher risk of post-operative erectile dysfunction.
- Penile implant — the answer when significant ED accompanies the curvature, since it addresses both at once. Straightening can be done during the same operation.
The overlap with erectile dysfunction
The two conditions travel together, in both directions. The plaque itself can interfere with the veno-occlusive mechanism that keeps blood in, and the anxiety and pain of a changing curvature affect erections on their own.
That overlap matters for treatment choice. Collagenase guidance assumes intact erectile function. Grafting surgery risks worsening ED. And if your ED is already significant, an implant addresses both problems in one procedure rather than sequencing two.
What to do first
- 1See a urologist, ideally one who treats Peyronie's regularly. This is a condition where experience shows.
- 2Get the phase established. Active or stable determines everything that follows.
- 3Document the curvature — photographs of an erection from above and the side, dated. It is awkward and it is the most useful thing you can bring to an appointment.
- 4Ask about collagenase specifically, and whether your curvature and plaque location fit the studied population.
- 5Do not buy a device or supplement on the strength of an advert while you are waiting.
- 6Mention any Dupuytren's contracture in your hands — the two conditions are associated and it is useful context.
Peyronie's has a genuinely approved treatment and genuinely effective surgery. It also has a marketing industry built around the fact that men frequently do not want to show this to a doctor. The second is much easier to reach than the first, which is exactly the problem.
Common questions
Will Peyronie's disease go away on its own?
Sometimes it improves during the active phase, but spontaneous resolution is uncommon and most men are left with some degree of stable curvature. Waiting indefinitely to see is not a strategy — get the phase established so you know whether you are waiting for stability or already at it.
Does Xiaflex straighten the penis completely?
No. Reported mean improvement in curvature is in the region of 29–34%, which can be genuinely meaningful without being a cure. It also carries real risks including corporal rupture and haematoma, which is why it is given under a restricted programme by trained clinicians.
Do traction devices work?
Medical traction protocols have some supporting evidence, but they require many hours a day over months and adherence is the main limitation. That is a different thing from a stretching device bought online on a promise of straightening a curve — Peyronie's is a condition where the wrong mechanical intervention can worsen things.
Is vitamin E worth trying?
It is widely sold for Peyronie's and weakly supported. Guidance does not endorse oral agents such as vitamin E, colchicine, or pentoxifylline for reducing curvature. If you want something with evidence behind it, that conversation is about collagenase or surgery.
Can I have surgery straight away?
Not while the disease is active. Surgical correction is for stable disease — operating on a curve that is still changing risks correcting to a shape that then continues to shift. Stability generally means several months without change in curvature and without pain.
Can I still use ED medication with Peyronie's?
Usually yes, and PDE5 inhibitors are commonly used alongside treatment. Significant curvature is a caution for vacuum devices and injection therapy, though, so tell whoever manages your ED that you have Peyronie's rather than treating them as separate problems.
