Key points

  • Peyronie’s disease involves the development of fibrous scar tissue inside the penis, causing curved, painful erections.
  • It is different from a natural slight curve and often develops after age 40.
  • Symptoms typically progress through an acute (inflammatory) phase and a chronic (stable) phase.
  • Treatment options include medication, specialised injections, or surgery in severe cases.
  • Early diagnosis is essential for managing pain and preventing permanent deformity.

What is Peyronie’s Disease?

Peyronie’s disease is a condition where fibrous scar tissue, known as plaque, develops under the skin of the penis. This tissue is not cancerous, but it is less elastic than normal penile tissue. As a result, when the penis becomes erect, the plaque pulls on the surrounding tissue, causing the penis to bend or curve significantly.

While many men have a slight natural curve to their penis, Peyronie’s disease is characterised by a noticeable change in shape, often accompanied by pain or the feeling of a hard lump. In the UK, it is estimated to affect approximately 3% to 9% of adult men, though many cases likely go unreported due to embarrassment. The condition is most common in men over the age of 40, though it can occur at any age.

Common Symptoms and Signs

The symptoms of Peyronie’s disease can appear suddenly or develop gradually over time. They are generally categorised into the 'acute phase' (when the scar tissue is forming) and the 'chronic phase' (when the condition has stabilised).

  • Hard Lumps: You may feel flat lumps or a band of hard tissue (plaque) under the skin of the penis.
  • Significant Curvature: The penis may curve upwards, downwards, or to one side. In some cases, it may take on an 'hourglass' shape with a narrowed band around the shaft.
  • Painful Erections: Pain is common during the early stages, particularly when the penis is erect. This often subsides in the chronic phase.
  • Length and Girth Changes: Some men notice their penis becomes shorter or develops indentations.
  • Erectile Dysfunction: Difficulty getting or maintaining an erection is frequently reported alongside Peyronie’s.

What Causes Peyronie’s Disease?

The exact cause of Peyronie’s disease is not fully understood, but clinical evidence suggests it is often triggered by minor trauma or injury to the penis. This could occur during sex, athletic activity, or as a result of an accident. In most people, these minor injuries heal without issue; however, in those susceptible to Peyronie’s, the healing process goes wrong, leading to the formation of permanent scar tissue.

There is also a significant genetic link. Men with a family history of the condition are at higher risk. Additionally, Peyronie’s is strongly associated with Dupuytren’s contracture, a condition where similar scar tissue forms in the palms of the hands, causing the fingers to curl inwards. Other risk factors include certain connective tissue disorders, diabetes, and smoking, which can impair vascular health and wound healing.

Diagnosis and Clinical Stages

Diagnosis in the UK typically begins with a physical examination by a GP or a urologist. The doctor will feel the shaft of the penis to locate the plaque and may ask about the degree of curvature. In some instances, an ultrasound may be used to examine the internal tissue and blood flow.

Understanding the stages is vital for treatment planning:

  • The Acute Phase: Lasts between 6 and 18 months. This is when the plaque is still forming, the curve may be worsening, and pain is most prevalent.
  • The Chronic Phase: The plaque stops growing and the curve becomes stable. Pain usually disappears, but the physical deformity remains. Most surgical interventions are delayed until the patient has been in the chronic phase for at least six months.

UK Treatment Options and Management

Treatment is not always necessary if the curve is mild and does not interfere with sexual function. However, if the condition causes distress or physical difficulty, several options are available on the NHS or through private urology services.

  • Traction Devices: Mechanical devices designed to stretch the penis can help reduce curvature and regain lost length, particularly when used in the early stages.
  • Injections: Medicines such as collagenase (Xiapex), although restricted in some NHS regions, or verapamil can be injected directly into the plaque to help break it down.
  • Oral Medications: While some medications are prescribed to manage pain, their effectiveness in reducing the actual curve is generally considered limited by NICE guidelines.
  • Surgery: If the condition is severe and stable, surgery may be an option. Procedures include 'plication' (pinching the unaffected side to straighten the penis) or 'grafting' (removing the plaque and replacing it with a tissue patch).

When to See an Online GP

Many men feel hesitant to discuss changes to their penile health, but Peyronie’s disease is a recognised medical condition that requires professional assessment. You should consult a GP—whether in-person or via a private online consultation—if you notice any new lumps, a significant change in the shape of your penis, or if erections have become painful.

An online GP can provide a safe, confidential environment to discuss your symptoms, offer advice on pain management, and provide the necessary referrals to a urologist if specialized treatment is required. Early intervention during the acute phase is often the best way to manage the long-term progression of the condition. If you are experiencing erectile dysfunction alongside these changes, an online GP can also discuss suitable treatments for that aspect of your health.

Red flags — when to seek urgent help

Call 999 or go to A&E if you experience any of the following:

  • Sudden, severe pain in the penis following a 'popping' sound (potential penile fracture)
  • Inability to pass urine
  • Severe bruising or swelling of the penis after trauma
  • Rapidly worsening curvature that prevents intercourse
