Quick Navigation
Peyronie's disease is scar tissue (plaque) forming in the tough layer under the skin of the penis, causing a curve, indentation, shortening or pain during erection. It is not cancer or an infection. Pain usually eases within a year or so, but the curve rarely disappears on its own; traction, medicines and surgery are the main options.
Peyronie's disease is a condition in which fibrous scar tissue forms inside the penis. The result is a noticeable curve, pain or a change in shape during erection. It is far more common than the silence around it suggests. It can dent confidence and strain a relationship long before a man mentions it to anyone.
The good news: once it is properly assessed, most men manage it well. This guide explains what is happening, why it develops, the two phases it moves through, and the options a urologist may discuss with you.
Key Takeaways
- Peyronie's disease is scar tissue (plaque) in the layer that stretches during an erection, so the penis bends, narrows or shortens where the plaque sits.
- It is benign: not cancer, not a sexually transmitted infection, and not something you did wrong.
- It has an active phase (pain, changing curve, up to 12 to 18 months) and a stable phase (pain settled, curve fixed); treatment choices depend on the phase.
- Options range from watchful monitoring and traction devices to plaque injections and, for stable severe curves, surgery.
- Sudden severe pain with a snap or bruising during sex is not Peyronie's; it is a penile fracture and an emergency.
What Is Peyronie's Disease?
Under the skin of the penis is a tough, elastic sheath called the tunica albuginea. It stretches evenly during an erection, which is what keeps the penis straight. In Peyronie's disease, a patch of scar tissue, called a plaque, forms in this layer. Scar tissue does not stretch. So when the rest of the sheath expands, the scarred area holds back, and the penis bends, narrows or shortens at that point.
The plaque is benign. It is not cancer, and Peyronie's disease is not caused by any sexually transmitted infection. Burning when passing urine, discharge or sores are not features of it. Those point towards a urine infection or STI in men and need a different assessment.
A curve you have always had is different
Many men have a mild natural curve since puberty, with no lump and no pain. That is congenital curvature, not Peyronie's disease. Peyronie's is a new change in adulthood, usually with a plaque you can feel, and often with pain at first.
What Are the Symptoms of Peyronie's Disease?
Peyronie's disease symptoms may appear suddenly or build over weeks to months. Typical features include:
- A hard lump or band of tissue you can feel under the skin of the penis
- A curve in the erect penis, upwards, downwards or to one side
- A painful erection, or pain during intercourse, usually most noticeable in the early months
- Shortening of the penis
- An indentation, or an hourglass-like narrowing of the shaft
- Difficulty with penetrative sex
- Erection problems in some men
Pain usually fades over time even if the curve stays. The emotional impact is real. Anxiety, avoiding intimacy and lower self-esteem are common, and they are a valid reason to seek help on their own.
What Causes Peyronie's Disease?
The exact cause is not fully understood. The best current explanation is repeated minor injury to the erect penis, during sex or other activity, followed by abnormal healing. Instead of normal tissue, the body lays down scar. Not every man who injures his penis develops it, so how each man heals clearly plays a part.
Other factors raise the risk. Some families have a genetic tendency. It is linked with other scarring conditions of connective tissue, such as Dupuytren's contracture of the hand, and possibly with immune factors. It is most often diagnosed in middle-aged and older men, but younger men can develop it too.
The Two Phases: Active and Stable
Doctors describe two Peyronie's disease stages, active and stable, and knowing which one you are in matters more than anything else when choosing treatment.
| Feature | Active (acute) phase | Stable (chronic) phase |
|---|---|---|
| Timing | The first several months, up to 12 to 18 months | After the active phase has settled |
| Pain | Common, especially with erections | Usually gone |
| Curve | Still changing; may worsen or occasionally improve | Fixed; no longer progressing |
| Usual approach | Monitor, ease pain, protect from further injury; traction may be started | Decide on lasting treatment, including surgery if the curve gets in the way of sex |
Surgery is generally not offered during the active phase, because the curve is still moving. That is one reason early assessment helps. It lets the specialist track the change and time any intervention properly.
What Are the Treatment Options?
Not every man needs active treatment. A mild curve that does not get in the way of sex or cause distress can simply be watched. When treatment is wanted, the options fall into three groups.
Non-surgical measures
- Oral medicines to ease pain in the early phase; their effect on the curve itself is limited.
- Penile traction devices, worn daily for several months, to encourage gradual straightening and protect length.
- Vacuum erection devices in selected cases, particularly where erections are also weaker.
Injection therapy
Medicines can be injected into the penile plaque, under local anaesthetic, to soften the scar and reduce the curve. Which medicine, how many sessions, and whether traction is added are decisions for your urologist. Results vary from man to man.
Surgery
For a stable, marked curve that prevents sex, surgery is an option. Plication shortens the longer side to straighten the penis. Grafting lengthens the scarred side. A penile implant is considered when erection problems are also severe. Each has trade-offs in length, feeling and erection quality that a specialist will explain before you decide.
The starting point for any penile curvature treatment is a specialist urology assessment, where the size of the bend, erection quality and your own goals are weighed together.
Living With Peyronie's Disease
Two things ease the burden more than any device: talking openly with your partner, and getting specialist advice early instead of waiting to see. Many men keep a satisfying intimate life with the right management. Treating any erection difficulty alongside the curve is part of that.
Blood vessel health matters too, because erections depend on it. Not smoking, a healthy weight, good blood pressure control and keeping diabetes well managed all support erections. They do not dissolve existing scar tissue, but they protect what works.
When Should You See a Doctor?
See a urologist as soon as you notice a new curve, a lump you can feel, pain with erections, or any change that makes sex difficult or worries you. Early assessment lets the active phase be watched and options be discussed at the right time. Waiting for it to "settle" often just means missing the window when the curve could still be influenced.
This is an emergency, not Peyronie's
Sudden severe pain during sex with a crack or pop, followed by rapid swelling and bruising, is a penile fracture. It needs urgent surgical repair. Go to an emergency department at once; do not wait for a clinic appointment.
Unittas Hospital's emergency department is the place for that. For everything else, if a face-to-face visit has put you off asking, a confidential sexual health consultation or an online urologist consultation is a private way to start.
Peyronie's disease is a physical condition with physical solutions, and nothing about it is shameful. If you have noticed a new curve, lump or pain, especially if it affects sex or your peace of mind, get it assessed early, while the options are widest.
Frequently Asked Questions
Is Peyronie's disease common?
It affects a noticeable minority of men, mostly over 40, and many cases go unreported because men are embarrassed to raise it. Urologists see it regularly.
Does the curve always get worse?
No. Some men stabilise or even improve slightly once the active phase ends. What it does not usually do is disappear on its own.
Can Peyronie's disease go away on its own?
Pain often settles by itself. The curve rarely disappears completely without treatment, although mild cases may become less troublesome over time.
Is the condition related to cancer?
No. The plaque is benign scar tissue and has no link to penile cancer.
Which doctor should I see for Peyronie's disease?
A urologist. Seeing a urologist for Peyronie's disease early, while the curve is still changing, keeps the widest range of options open. If a face-to-face visit puts you off, a confidential sexual health or online urologist consultation is a private way to start.
Does treatment restore full length?
Some approaches aim to keep or improve length, but results vary. Some straightening operations trade a little length for a straighter penis, so realistic expectations are set at consultation.
How long do I need to use a traction device?
Protocols usually involve daily use for several months. Your clinician will advise on the hours per day and the total duration.
Will surgery affect sensation?
Modern techniques aim to preserve sensation, though temporary changes can occur. This is discussed in detail before any operation.
Is erectile dysfunction always present?
No. Many men keep good erections. Those who develop difficulties can have them treated alongside the curvature.
Can Peyronie's disease affect fertility?
The condition itself does not usually affect sperm, though difficulty with sex can make conceiving naturally harder.
Noticed a new curve, lump or pain?
A confidential urology or sexual health consultation is the right first step, and the earlier the better.
