Peyronie’s disease is a condition where firm scar tissue forms inside the penis and bends the erection. The curve may point up, down, sideways, or in more than one direction. Some men also notice a hard lump, penile pain, shortening, narrowing, weaker erections, or difficulty having sex. The change can appear suddenly or build over several months.
A mild curve that does not cause pain or sexual problems may only need monitoring. A curve that makes penetration difficult, keeps getting worse, or comes with erectile dysfunction deserves a urology evaluation. Treatment depends on whether the condition is still changing or has become stable. Options may include pain control, penile traction, injections, erectile dysfunction treatment, or surgery. The goal is not always a perfectly straight penis. The goal is usually a comfortable, usable erection with the lowest reasonable risk.

What Peyronie’s Disease Is
Peyronie’s disease happens when scar tissue forms in the tunica albuginea, the strong outer layer around the erectile chambers of the penis. During an erection, normal tissue stretches evenly. Scarred tissue does not stretch the same way, so the penis bends toward the tight area.
The scar is often called a plaque. It is not the same as plaque in the arteries, and it is not cancer. A Peyronie’s plaque is usually a firm, flat, or cord-like area under the penile skin. Some plaques can become calcified, meaning they harden with calcium deposits.
The condition is different from a natural curve that has been present since puberty. A lifelong curve that has not changed is usually congenital penile curvature. Peyronie’s disease is acquired, which means it develops later. Men often notice a new bend, a new lump, pain with erections, or a change in length or shape.
A curve does not need treatment just because it exists. Many men have some natural curvature. Peyronie’s disease becomes a medical concern when the curve is new, painful, worsening, distressing, or interfering with sex.
The curve may look different from one man to another. Some have a single upward bend. Others have a sideways curve, downward curve, indentation, hourglass narrowing, hinge effect, or loss of girth. A hinge effect means the erection buckles at a weak or narrowed point, even if the bend itself does not look extreme.
Symptoms and Patterns Men Notice
A new curve during erection is the most common sign. The penis may look straight when soft, then bend only when firm. This is why men often notice the problem during sex, masturbation, or morning erections.
Common symptoms include:
- A bend that points upward, downward, sideways, or in multiple directions
- A hard lump, ridge, or flat plaque under the skin
- Pain during erection, especially early in the condition
- Penile shortening or loss of stretched length
- Narrowing, dents, or an hourglass shape
- Trouble with penetration because of the angle or instability
- Erectile dysfunction, either from blood flow problems, anxiety, pain, or the deformity itself
- Less confidence, avoidance of sex, or relationship stress
Pain can be misleading. Some men have pain early, then the pain fades while the curve remains. Others have little pain but still develop a significant bend. A curve that keeps changing is usually more important than pain alone.
The degree of curvature matters, but it is not the only issue. A 25-degree curve may not interfere with sex. A 40-degree curve may be manageable for one couple and difficult for another. A smaller curve with an hourglass narrowing can be more disruptive than a larger smooth curve because the penis may buckle.
Men sometimes confuse Peyronie’s disease with an injury such as penile fracture. A penile fracture is usually sudden, often with a popping sound, immediate pain, swelling, bruising, and rapid loss of erection. That is an emergency. Peyronie’s disease usually develops over weeks or months, although the first noticeable change can feel sudden.
Causes and Risk Factors
Peyronie’s disease is usually linked to abnormal wound healing after small injuries to the penis. These injuries may happen during sex, sports, or other pressure on an erect penis. Many men do not remember a specific injury. Repeated minor bending may be enough in someone prone to scarring.
The plaque forms when the body lays down collagen and other scar tissue in a way that does not remodel normally. The result is a stiff patch that pulls the erection out of line.
Risk factors include:
- Age, especially middle age and older
- Erectile dysfunction, which may make the penis more likely to bend during sex
- Diabetes or blood vessel disease
- Smoking or other circulation problems
- Family history of Peyronie’s disease
- Dupuytren’s contracture, a hand condition that causes thick cords in the palm
- Prior prostate surgery or pelvic surgery in some men
- Repeated penile trauma
Peyronie’s disease is not caused by poor hygiene, masturbation, sexually transmitted infections, or lack of testosterone. Low testosterone may affect libido and erections, but it is not usually the direct cause of the plaque. Men with erection problems should still be evaluated because treating erectile dysfunction can improve sexual function even when the curve remains.
It is also not contagious. A partner cannot “catch” Peyronie’s disease through sex. However, the condition can affect both partners because pain, fear of injury, and changes in penetration may change sexual habits.
When to See a Urologist
A mild, painless curve that has been present for years usually does not need urgent care. A new or changing curve should be checked, especially if it affects erections, sex, or confidence.
Make a urology appointment if you notice:
- A new bend that was not there before
- A hard plaque or lump along the shaft
- Painful erections that last more than a few weeks
- Worsening curvature over time
- Penile shortening or narrowing
- Buckling during sex
- New erectile dysfunction
- Difficulty with penetration
- Major anxiety or avoidance of intimacy because of the change
Seek urgent care if there was a sudden injury during sex followed by a pop, severe pain, swelling, purple bruising, or immediate loss of erection. That pattern is more concerning for fracture than Peyronie’s disease.
A urologist is especially helpful when the curve is hard to measure, the plaque feels calcified, erections are unreliable, or surgery is being considered. Men who are unsure where to start can use symptoms such as curvature, penile pain, erection changes, or urinary problems as reasons to see a urologist.
Early evaluation does not mean early surgery. In many cases, the first visit is about confirming the diagnosis, measuring the problem, managing pain, protecting erections, and watching whether the deformity stabilizes.
How Doctors Diagnose Peyronie’s Disease
Diagnosis usually starts with a medical and sexual history. The doctor may ask when the curve began, whether it is changing, whether erections are painful, whether penetration is possible, and whether erectile function has changed.
A physical exam checks for plaques, tenderness, penile length, and other findings such as Dupuytren’s contracture in the hands. The plaque may be easy to feel when the penis is soft, but the true curve can only be judged during erection.
Doctors may ask for erection photos taken at home from the top and side. These should be clear, private, and used only for medical evaluation. Some offices measure curvature after an in-office injection that produces an erection. This can show the angle, direction, narrowing, hinge effect, and erection firmness more accurately.
Ultrasound may be used when the doctor needs more detail. It can help identify plaque location, calcification, and blood flow problems. Doppler ultrasound is more likely when erectile dysfunction is part of the picture or when surgery is being planned.
Routine MRI or CT scans are usually not needed. Blood tests do not diagnose Peyronie’s disease, but they may be ordered if erectile dysfunction, diabetes, low testosterone symptoms, or cardiovascular risk factors are present.
A useful home record includes:
- The month symptoms started
- Whether the curve is improving, stable, or worsening
- Pain level during erections
- Whether penetration is possible
- Any erectile dysfunction or loss of firmness
- Photos or measurements if requested by the clinician
- Treatments already tried, including supplements or devices
This record helps separate active disease from stable disease, which is one of the most important treatment decisions.
Active Phase vs Stable Phase
Peyronie’s disease often has two phases. The active phase is the period when pain, plaque formation, and shape changes may still be developing. The stable phase begins when the curve and symptoms stop changing.
The active phase can last months. During this time, the curve may worsen, pain may come and go, and new narrowing may appear. Treatment is usually conservative unless symptoms are severe. The focus is pain control, sexual adjustments, erection support, and sometimes traction or other nonsurgical options.
Stable disease means the curve has not changed for at least several months and pain has usually improved or resolved. This is when injections or surgery are more commonly considered, especially if the deformity prevents sex.
A simple way to think about it:
| Feature | Active phase | Stable phase |
|---|---|---|
| Curve | May still be changing | Not changing for several months |
| Pain | More common, especially with erections | Often gone or much improved |
| Main goal | Reduce pain, protect function, monitor progression | Correct function-limiting deformity |
| Common options | NSAIDs, erection support, traction, observation | Traction, injections, surgery, ED treatment |
| Surgery | Usually avoided | Considered if sex is difficult or impossible |
One common mistake is rushing into a procedure while the curve is still changing. Surgery performed too early may need revision if the disease progresses afterward. Another mistake is waiting too long when sex has become impossible and distress is high. Stable, function-limiting Peyronie’s disease is treatable.
Nonsurgical Treatment Options
Nonsurgical treatment is often the first step, especially when symptoms are early, mild, or not yet stable. The right option depends on pain, curvature, erectile function, plaque features, cost, access, and how much effort the patient is willing to put into home therapy.
Observation
Observation is reasonable when the curve is mild, sex is still possible, pain is low, and the deformity is not worsening. Monitoring does not mean ignoring the condition. It means tracking changes and returning for care if the curve progresses, erections weaken, or distress grows.
Pain control
Nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen, may help erection-related pain during the active phase when they are safe for the individual. Men with kidney disease, stomach ulcers, blood thinners, uncontrolled blood pressure, or heart disease should ask a clinician before using them regularly.
Shockwave therapy may reduce penile pain in some men, but it should not be expected to straighten the penis. That distinction matters because shockwave marketing can make it sound like a curvature treatment when the evidence is stronger for pain relief than for shape correction.
Oral pills and supplements
Many pills and supplements have been promoted for Peyronie’s disease, including vitamin E, omega-3 fatty acids, coenzyme Q10, pentoxifylline, potassium para-aminobenzoate, and others. Evidence is mixed, and no over-the-counter supplement reliably reverses a significant curve.
Daily PDE5 inhibitors, such as tadalafil, may be used when erectile dysfunction is also present. They can support firmer erections and may help some men stay sexually active during treatment. They should not be viewed as a guaranteed way to dissolve plaque or restore length.
Avoid spending large amounts on supplement stacks that promise scar removal. A treatment plan should be based on measurable goals: less pain, better erections, less curvature, improved penetration, or less distress.
Penile traction therapy
Penile traction uses a medical device to gently stretch the penis over time. It may help reduce curvature, preserve or improve length, and support tissue remodeling. It requires consistency. Some devices require long daily use, while newer protocols may involve shorter daily sessions.
Traction is not the same as unsafe hanging weights or aggressive stretching. Too much force can worsen pain or cause injury. Men considering this option should use a device designed for medical traction and follow a clinician’s instructions. A separate discussion of penile traction therapy can be helpful for understanding realistic length claims, safety, and expectations.
Vacuum erection devices
A vacuum erection device pulls blood into the penis using negative pressure. It is often used for erectile dysfunction, and some clinicians include it in Peyronie’s rehabilitation plans. It may help maintain tissue stretch and support erections, but evidence for straightening as a stand-alone treatment is limited.
Men using a vacuum device for Peyronie’s disease should ask whether to use it with or without a constriction ring. A constriction ring is used for intercourse in erectile dysfunction, but rehabilitation protocols may differ. For broader ED treatment choices, vacuum erection devices have their own benefits and safety limits.
Collagenase injections
Collagenase clostridium histolyticum is an enzyme injection used to break down collagen in the plaque. In the United States, it is used for selected men with Peyronie’s disease, usually when the plaque is palpable, the disease is stable, erectile function is adequate, and curvature is within a treatable range.
Treatment involves injections into the plaque and penile modeling, which means controlled bending or stretching guided by the clinician’s protocol. Bruising, swelling, and pain are common after injections. Rarely, serious injury such as corporal rupture can occur, so men must follow instructions about avoiding sex and forceful activity after treatment.
Collagenase is not ideal for every deformity. Severe hourglass narrowing, hinge instability, heavy calcification, ventral plaques near the urethra, or very severe curvature may require a different plan.
Other injections
Some clinicians use injections such as verapamil, interferon, or hyaluronic acid in selected cases. Evidence varies by medication, study design, and patient group. These options should be discussed in terms of expected curvature change, number of visits, side effects, cost, and whether the treatment is considered standard, off-label, or investigational.
Platelet-rich plasma and stem cell-based treatments are often advertised for sexual health. At this time, they should be approached carefully for Peyronie’s disease because protocols are not standardized and strong long-term evidence is limited.
Surgery and Recovery
Surgery is usually reserved for stable Peyronie’s disease that prevents comfortable sex or causes major functional problems. It is not usually done just because a plaque exists. The best procedure depends on curvature severity, penile length, erectile function, narrowing, and patient priorities.
The three main surgical paths are plication, incision or grafting, and penile implant surgery.
Plication
Plication straightens the penis by shortening the longer side opposite the curve. It is often used when erections are firm, penile length is adequate, curvature is less severe, and there is no major hourglass or hinge deformity.
The main advantage is that plication is usually less complex than grafting and has a lower risk of causing new erectile dysfunction. The main tradeoff is penile shortening. Some men notice this more than others, especially if Peyronie’s disease already caused length loss.
Incision or grafting
Grafting procedures involve cutting or opening the tight scarred side and placing graft material to cover the defect. This can be considered when curvature is severe, the penis is significantly shortened, or there is a complex deformity such as hourglass narrowing.
Grafting may better address certain deformities, but it is more complex and has a higher risk of postoperative erectile dysfunction than plication. It is generally best for men with good erections before surgery.
Penile implant surgery
A penile implant is considered when Peyronie’s disease occurs with erectile dysfunction that does not respond well to pills or injections. The implant creates reliable rigidity, and the surgeon can often correct curvature during the same operation with modeling, plication, or grafting when needed.
A penile implant does not restore the penis to its pre-Peyronie’s length. It can greatly improve rigidity and sexual reliability, but expectations must be clear. Men considering this route should understand device types, infection risk, revision risk, recovery, and satisfaction factors. A full guide to penile implant surgery can help frame those questions before a consultation.
Recovery varies by procedure. Many men need several weeks before returning to sexual activity. Swelling, bruising, temporary sensitivity changes, and discomfort are common early. The surgeon’s instructions matter more than a generic timeline because grafting, plication, and implants differ.
Before surgery, ask:
- Is my disease stable enough for surgery?
- Which procedure fits my curve and erection quality?
- How much length might I lose or preserve?
- What is the risk of new or worse erectile dysfunction?
- Could I still need ED medication afterward?
- What results would count as “functionally straight”?
- How many of these procedures does the surgeon perform each year?
- What restrictions apply after surgery, and for how long?
A good surgical plan is honest about tradeoffs. Straightening, firmness, length, sensation, and risk do not all improve equally with every procedure.
Sex, Confidence, and Daily Life
Peyronie’s disease affects more than anatomy. Men may feel embarrassed, angry, anxious, or less masculine. Some avoid sex because they fear pain, rejection, or further injury. Partners may misread avoidance as loss of attraction.
Talking early can prevent silence from becoming the bigger problem. A simple explanation works: “My erection has developed a curve and sometimes hurts. I’m getting it checked, but I may need to change positions or slow down for now.”
During the active phase, avoid positions that force the penis to bend sharply. Use lubrication if friction or awkward entry increases pain. Stop if the penis buckles, slips out forcefully, or causes sharp pain. Painful penetration should not be pushed through; it can worsen fear and may increase injury risk. Men with ongoing discomfort during sex may also benefit from guidance on painful sex in men.
Mental health support can be part of treatment. This does not mean the condition is “in your head.” It means a visible sexual change can affect confidence, arousal, erections, and relationships. Sex therapy, couples counseling, or individual therapy can help when anxiety or avoidance becomes a pattern.
Lifestyle changes will not dissolve a plaque, but they can support erection quality. That matters because a firm erection is often easier to use and less likely to buckle than a weak one. Helpful steps include not smoking, managing diabetes, controlling blood pressure, exercising regularly, limiting heavy alcohol use, and treating sleep apnea if present.
Be careful with online before-and-after claims. Peyronie’s disease is emotionally stressful, and that makes men vulnerable to expensive devices, supplements, and “regenerative” packages. A credible plan should include diagnosis, phase assessment, measured curvature, realistic goals, possible side effects, and a follow-up timeline.
