Most men notice something is different. A slight curve during erection. A firm spot beneath the skin. Some discomfort that did not used to be there. Most dismiss it. They assume it is normal variation, a pulled muscle, or something that will resolve on its own.
For many, it does not resolve. What they are experiencing may be Peyronie’s disease — a progressive connective tissue condition that affects the internal structure of the penis. Left unaddressed in its early stages, it can worsen significantly over time.
This guide explains what Peyronie’s disease is, the early symptoms most men overlook, and why early detection matters more than most people realise.
What Is Peyronie’s Disease?
Peyronie’s disease is a condition in which scar tissue — called a plaque — forms beneath the skin of the penis within the tunica albuginea. The tunica albuginea is the fibrous sheath that surrounds the erectile chambers. When this tissue develops abnormally, it loses its elasticity. The result is a penis that curves, bends, or shortens during erection.
The condition is named after French surgeon François Gigot de la Peyronie, who first described it formally in 1743. It is not a new condition. It is, however, a frequently misunderstood and underdiagnosed one.
Peyronie’s disease is classified as a fibromatous disorder. The leading hypothesis is that repeated micro-trauma to the erect penis — often during intercourse — triggers an abnormal healing response in men who are genetically predisposed. Instead of resolving cleanly, the inflammation causes disordered collagen deposition, forming a rigid plaque within the penile tissue (Devine et al., J Urol, 1997).
Prevalence estimates vary widely due to underreporting — many men are too embarrassed to seek a diagnosis. Studies suggest the condition affects between 1% and 20% of men, with the most commonly cited community-based figure sitting at approximately 3.2% (Schwarzer et al., BJU Int, 2001). Among men presenting for erectile dysfunction evaluation, the rate rises considerably — to as high as 16% in some studies (NCBI Bookshelf, StatPearls, 2024). The true number is almost certainly higher than any figure currently published.
The condition is most common in men over 40, but it is not exclusive to older men. Research confirms that nearly 10% of men who present with Peyronie’s disease are under 40 (Mulhall et al., PubMed, 2013). Cases have also been recorded in teenagers.
Peyronie’s Disease Symptoms: What the Early Signs Look Like
The earliest signs of Peyronie’s disease are subtle. That is precisely why so many men miss them, or attribute them to something else entirely.
Understanding the symptom progression — from early to later stages — is the first step toward acting at the right time.
Penile Pain During Erection
Pain is often the first sign. It tends to occur during erection or sexual activity and is usually localised — concentrated along one area of the shaft. Men frequently attribute this to minor injury or muscle strain. In some cases, pain occurs even without an erection.
Pain is most common in the acute, or active, phase of the disease. This is the period in which the plaque is still forming and inflammation is present. It can last anywhere from six to eighteen months. For many men, the pain diminishes as the plaque stabilises — but the structural changes remain.
A Palpable Lump or Hard Area
Before any curvature becomes visible, many men notice a firm area or small lump beneath the skin of the penis. This is the plaque itself. It may feel like a cord, a nodule, or a thickened ridge. It does not move when pressed.
This sign is frequently dismissed. Men often assume it is a cyst, a vein, or a harmless benign growth. It is not.
Penile Curvature on Erection
As the plaque develops and contracts the surrounding tissue, curvature becomes apparent during erection. The direction of the curve — upward, downward, or to one side — depends on the location of the plaque. In some men, the deviation is mild. In others, it is severe enough to make sexual intercourse difficult or impossible.
A natural curve in the penis is common and does not indicate Peyronie’s disease. The key distinction is whether curvature has developed or worsened over time. An acquired curve — one that was not present before — is clinically significant.
We discuss this distinction in more detail in our blog: What Causes Penile Curvature? 4 Reasons.
Shortening of the Penis
Plaque formation causes the affected tissue to become inelastic. As scar tissue contracts, the penis may appear shorter during erection. This is not imagined. It is a structural consequence of the fibrosis. Some men also report narrowing or an hourglass-shaped indentation along the shaft.
Erectile Dysfunction
Peyronie’s disease and erectile dysfunction are frequently linked. The structural changes in the tunica albuginea can disrupt the vascular mechanics required for a firm erection. Blood flow may be impaired, or the chambers may not expand properly due to the restricted tissue.
Research confirms that up to 81% of men with clinically significant depression linked to their condition also reported difficulties with erections (Wikipedia, Peyronie’s Disease, citing multiple studies). The relationship between Peyronie’s disease and ED is bidirectional — each can worsen the other.
Why Men Ignore These Signs — and Why That Is a Problem
Peyronie’s disease carries a significant psychological burden. In clinical studies, 81% of men diagnosed with the condition reported emotional difficulties. Nearly half met criteria for clinically meaningful depression. Many withdrew from sexual relationships entirely (Wikipedia, citing multiple clinical studies).
Despite this, the average man delays seeking help for months — sometimes years. The reasons are consistent: embarrassment, denial, the hope that it will resolve on its own, and a lack of awareness that effective options exist.
The delay is medically significant. Peyronie’s disease has two distinct phases:
The acute phase — typically the first six to eighteen months — is characterised by active inflammation, pain, and progressing curvature. This is when the condition is most responsive to treatment. Intervening during this phase offers the best chance of limiting structural progression.
The chronic phase — once the plaque has stabilised and calcified — presents a more established structural problem. Intervention remains possible, but the treatment landscape changes.
Early action is not about being anxious. It is about protecting function, managing progression, and avoiding the compounding difficulty of addressing an advanced case.

Who Is at Risk of Peyronie’s Disease?
Peyronie’s disease can affect any man. However, certain risk factors appear consistently in the research:
Age — The condition is most prevalent in men between 45 and 60, though it can and does occur at any age. Prevalence increases with age: from approximately 1.5% in men aged 30–39 to 6.5% in men over 70 (Schwarzer et al., BJU Int, 2001).
Penile trauma — Micro-injury during intercourse is considered the most common trigger. The damage may be minor enough that the man does not recall a specific incident.
Diabetes and cardiovascular disease — Both are strongly associated with Peyronie’s disease. Men with diabetes show higher rates of both the condition and co-occurring erectile dysfunction. Vascular health appears to be a common denominator.
Family history — Peyronie’s disease is associated with Dupuytren’s contracture (a fibrotic condition of the hand) and shows familial patterns, suggesting a genetic predisposition in some men.
Connective tissue disorders — Men with autoimmune or connective tissue conditions appear at elevated risk.
If you are experiencing erectile difficulties alongside any of the symptoms described above, there is also a meaningful overlap with the vascular drivers of ED. We discuss these in more detail on our Erectile Dysfunction service page.
How Peyronie’s Disease Is Diagnosed
Diagnosis is typically clinical — based on a physical examination and the patient’s reported history of symptoms. A specialist will assess the presence of palpable plaque, the degree of curvature, and the phase of the disease (acute or chronic).
Penile ultrasound may be used to assess plaque size, location, calcification, and blood flow. It provides more precise information than physical examination alone, particularly when planning treatment.
A thorough assessment also considers erectile function, psychological impact, and co-existing conditions such as diabetes or hypertension — factors that influence both the severity of the condition and the most appropriate approach to management.
What Are the Treatment Options?
Peyronie’s disease is a medical condition with recognised management pathways. It is not something a man must simply live with.
Non-surgical options are generally recommended in the acute phase and for mild-to-moderate cases. These include extracorporeal shockwave therapy (ESWT), intralesional injections, traction therapy, and regenerative treatments such as PRP and Carboxy CO₂ therapy.
At Shockwave Clinic, our Peyronie’s Disease treatment programme combines multiple modalities — including focused ESWT shockwave therapy, EMTT, PRP, Carboxy CO₂, and infrared light therapy — tailored to the individual’s presentation, phase of disease, and goals. The approach is non-invasive, drug-free, and does not require surgery or anaesthesia.
Shockwave therapy works by delivering targeted acoustic waves to the affected tissue. These waves promote circulation, stimulate cellular repair, and target the fibrotic plaque directly. The same technology used in our erectile dysfunction programme has well-established evidence across men’s urological health.
For men managing both Peyronie’s disease and erectile dysfunction, treatment of both conditions may proceed simultaneously. We discuss the role of shockwave therapy in ED management in our blog: Shockwave Therapy vs TRT: Which Helps Erectile Dysfunction Long-Term?
Frequently Asked Questions
What is Peyronie’s disease?
Peyronie’s disease is a condition in which fibrous scar tissue — called a plaque — forms within the tunica albuginea of the penis. This plaque reduces tissue elasticity and causes curvature, pain, and in some cases erectile dysfunction. It is a progressive connective tissue disorder that can worsen without treatment, particularly during the active phase.
What are the most common Peyronie’s disease symptoms?
The most commonly reported symptoms are penile curvature during erection, a palpable lump or firm ridge beneath the skin, pain during erection or sexual activity, and in some cases a shortening of the penis. Erectile dysfunction is also frequently associated with the condition.
Can Peyronie’s disease resolve on its own?
In a small proportion of cases, symptoms may stabilise. However, research indicates that in the majority of men, symptoms either remain stable or worsen without intervention. Spontaneous resolution is not a reliable outcome. Early assessment and management give the best chance of limiting progression.
Is Peyronie’s disease common?
Prevalence estimates range from 3% to 13% of men, with rates increasing with age and in men who also have erectile dysfunction or diabetes. Underreporting is significant due to embarrassment, meaning actual rates are likely higher than published figures suggest.
At what age does Peyronie’s disease occur?
Peyronie’s disease most commonly presents in men between 45 and 60 years of age. However, it can occur at any age — including in men under 40 and, in documented cases, teenagers. Younger men who develop the condition may experience more acute symptoms and faster progression.
Peyronie’s disease is not a condition to observe indefinitely. The earlier it is assessed, the more options are available — and the more effectively progression can be managed. If you have noticed any of the signs described in this guide, a private consultation with a specialist is the sensible next step.
At Shockwave Clinic, we provide confidential assessments and non-invasive treatment programmes for men managing Peyronie’s disease across South Africa. To take the first step, contact us via WhatsApp or visit our Peyronie’s Disease treatment page to learn more about our approach.
