Peyronie's disease is a condition in which scar tissue, called a plaque, forms inside the penis and makes it bend, narrow or shorten during erection. It often starts with pain and a firm lump. Treatment depends on the phase: pain relief, traction and monitoring while it is active, and injections or surgery once the curve is stable.
A new bend in the penis is worrying, and many men keep it to themselves for months. The good news is that Peyronie's disease is a known, well-studied condition, it is not cancer, and there are clear treatment options. This explainer covers what Peyronie's disease is, the common penile curvature causes, how doctors confirm it, and how Peyronie's disease treatment is chosen. For a closer look at day-to-day life with the condition, see living with penile curvature.
Peyronie's disease is an acquired curve or change in shape of the penis caused by scar tissue. The American Urological Association (AUA) guideline describes it as fibrosis, or scarring, of the tunica albuginea, which may come with pain, deformity, erection problems and distress.
The tunica albuginea is the strong, stretchy sheath wrapped around the two erectile chambers of the penis. When a patch of it turns into scar tissue, that patch cannot stretch. During an erection the healthy side lengthens and the scarred side does not, so the penis bends towards the plaque.
Our Peyronie's disease condition page covers the anatomy in more detail.
The most common symptoms of Peyronie's disease are a new bend in the erect penis and a firm lump in the shaft. Symptoms vary a lot between men, and some notice pain before they ever see a curve.
The emotional side matters too. Many men feel anxious, avoid intimacy or feel low about the change, and this deserves attention as much as the curve itself.
Penile curvature causes fall into two main groups: a curve you were born with (congenital curvature) and a curve that develops in adult life, which is usually Peyronie's disease. A slight bend is normal for many men and needs no treatment if it is painless and does not affect sex.
| Feature | Congenital penile curvature | Peyronie's disease |
|---|---|---|
| When it starts | Present from the first erections, usually noticed in the teens or twenties | Develops in adult life, most often after 40 |
| Cause | Uneven development of the erectile chambers before birth | Scar tissue (plaque) in the sheath around the erectile chambers |
| Lump in the shaft | No | Often yes |
| Pain | No | Common in the early phase |
| Does it change over time? | No, it stays the same | Can worsen for months, then stabilises |
| Treatment | None needed unless it affects sex; surgery is the only way to straighten it | Depends on the phase; non-surgical options and surgery |
Our penile curvature page explains how much bend is considered normal.
The exact cause of Peyronie's disease is not always known. The most accepted theory is small, repeated injuries to the erect penis, often during sex and often unnoticed, that heal with too much scar tissue in men who are prone to it. The NHS lists these risk factors:
Some men with Peyronie's disease also have Dupuytren's contracture, a similar scarring condition that pulls the fingers into the palm. Smoking and previous prostate or pelvic surgery are also linked with a higher risk.
Peyronie's disease runs in two phases, an active phase and a stable phase, and the phase decides which treatments make sense. The AUA guideline advises doctors to tell these apart because treatment options differ.
Pain usually settles on its own as the plaque matures. The curve is different: a small number of men see it improve, most see it stay about the same, and some see it get worse. That is why early assessment and regular monitoring are more useful than simply waiting.
Peyronie's disease is usually diagnosed from your history and a physical examination. The NHS says a doctor will ask about your symptoms, examine the penis and may arrange an ultrasound scan.
Because erection problems often travel with Peyronie's disease, erectile function is checked at the same visit. See erectile dysfunction for how that is assessed.
Peyronie's disease treatment depends on the phase, the size of the curve, and whether erections are still firm. Treatment may not be needed at all if symptoms are mild and sex is comfortable, which the NHS also notes. When treatment is needed, these are the main options.
| Treatment | Best suited to | What it aims to do | What to expect |
|---|---|---|---|
| Monitoring and pain relief | Active phase; mild disease in either phase | Control pain and track the curve | Anti-inflammatory painkillers are an option for pain in active disease, per the AUA guideline |
| Penile traction therapy | Active or stable phase | Limit shortening and reduce the curve a little | Daily use for several months; Mayo Clinic notes it is the only treatment shown to improve length |
| Injections into the plaque | Stable phase, selected curves | Soften the plaque and reduce the curve partly | A course over several months; collagenase, an enzyme that breaks down scar tissue, is one option |
| Shock wave therapy | Selected cases | Ease pain | The NHS lists it as a procedure that uses sound waves on the plaque |
| Plication surgery | Stable phase, good erections, moderate curve | Straighten by tightening the longer side | Reliable straightening with a small loss of length |
| Grafting surgery | Stable phase, good erections, severe curve or hourglass shape | Straighten while protecting length | Longer recovery and a higher risk of softer erections |
| Penile implant | Stable phase with erection problems that medicine does not fix | Straighten and restore firm erections together | A permanent decision, considered only after other options |
A few points help set realistic expectations:
Our Peyronie's disease treatment page explains each option, the recovery and who each one suits.
See a doctor if you notice a new curve, a lump in the shaft, painful erections, or any change that makes sex difficult. Early assessment helps, because some treatments work best while the disease is still active.
Emergency warning: a sudden snap or popping sound during sex, followed by immediate pain, rapid swelling and bruising, may be a penile fracture. This is a surgical emergency. Go to a hospital emergency department the same day, not a routine clinic appointment.
In our clinic in Surat, many men tell us they waited a year or more because they felt embarrassed or assumed nothing could be done. Most are relieved to learn that Peyronie's disease is common, that it is not cancer, and that the first step is simply a private conversation and an examination. Our guide to a confidential sexual health consultation explains what that first visit involves.
A new curve is a reason to get checked, not to worry in silence. Book a private consultation to find out which phase you are in and what your options are.
This page is for education and is not a substitute for medical advice. Do not start medicines, devices or creams for penile curvature without a doctor's review. A suspected penile fracture needs emergency care.
Peyronie's disease is a condition in which scar tissue, called a plaque, forms in the sheath around the erectile tissue of the penis. Because the scar cannot stretch, the penis bends, narrows or shortens during erection. It may cause pain and erection problems, mostly affects men over 40, and is not cancer.
Yes. Many men have a slight bend when erect, and a gentle curve that has always been there, causes no pain and allows comfortable sex is normal anatomy. It is worth seeing a doctor if the curve is new, getting worse, painful, or comes with a lump in the shaft.
The pain usually settles on its own as the plaque matures. The curve is different: a small number of men improve without treatment, most stay about the same, and some get worse. Because the curve rarely disappears completely, monitoring in the early phase is more useful than simply waiting.
Peyronie's disease is not life-threatening. It is not cancer and cannot spread to a partner. It can, however, make sex difficult, cause erection problems and affect confidence and relationships. Those effects are real and treatable, which is why assessment is worthwhile even when the curve looks mild.
Yes, the two often occur together. Scarring can affect how blood is held in the penis, causing softness beyond the curve, and pain or anxiety can also weaken erections. Shared risk factors such as diabetes and high blood pressure play a part, so doctors check erections at the same visit.
Often, yes. Many men with a mild or moderate curve continue to have comfortable sex. Avoiding forceful bending, using lubricant, changing positions and treating any erection problem all help. If the curve makes penetration difficult or painful for either partner, that is a good reason to seek treatment.
Surgery is considered once the disease is stable, meaning no pain and no change in the curve for several months, and when the bend makes sex difficult or impossible. It is not done in the active phase. If erections are also weak and do not respond to medicine, an implant may be advised.
