Peyronie's Disease — Penile Curvature, Plaque, and Treatment Options
Peyronie's disease is a condition in which fibrous scar tissue (plaques) forms within the tunica albuginea — the dense fibrous sheath surrounding the corpora cavernosa of the penis. As this scar tissue develops, it causes penile curvature, shortening, narrowing (the 'hourglass' deformity), pain during erection, and in many cases erectile dysfunction — both from the physical distortion and from the psychological distress the condition generates. Peyronie's disease affects approximately 3 to 9% of men — the true prevalence is likely higher, as stigma and embarrassment prevent many from seeking help.
Peyronie's disease is not a rare curiosity — it is a condition with a well-understood pathophysiology, an evidence base for treatment, and a range of both conservative and surgical options. No man with Peyronie's disease needs to simply accept the curvature and its consequences. At KIMS, the andrology team evaluates each case individually and recommends the appropriate treatment based on disease phase (active or stable), degree of curvature, presence of erectile dysfunction, and the patient's sexual function goals.
Cause and mechanism
How the plaque forms
Peyronie's disease begins with micro-trauma to the tunica albuginea — repetitive bending stress during sexual intercourse, particularly in men with a degree of vascular disease or connective tissue abnormality, causes small tears in the tunica. In most men these heal without consequence. In men predisposed to abnormal wound healing (genetic susceptibility — associated with HLA-B7 and Dupuytren's contracture — a similar fibrotic condition of the palmar fascia), the healing process generates excess fibrin deposition and collagen cross-linking, forming an inelastic fibrous plaque that restricts normal expansion of the tunica during erection, causing curvature toward the plaque.
Active vs stable phase
Peyronie's disease has two phases. The acute (active) phase — lasting 6 to 18 months, characterised by penile pain during erection, progressive curvature change, and palpable but evolving plaque. The chronic (stable) phase — curvature has stabilised (no further change for at least 3 months), pain has typically resolved, but the deformity and dysfunction persist. Treatment decisions differ significantly between phases.
Symptoms
Penile curvature during erection — dorsal (upward), ventral (downward), or lateral. Degrees range from mild (less than 30 degrees — often manageable) to severe (above 60 degrees — may prevent penetration).
Penile pain during erection — in the acute phase. Pain typically resolves spontaneously as the active phase transitions to stable.
Palpable plaque — a firm, non-tender nodule palpable along the shaft, most commonly on the dorsal surface.
Penile shortening — from the inelastic scar tethering the tunica.
Hourglass or waist deformity — narrowing or indentation at the plaque site.
Erectile dysfunction — in 30 to 50% of Peyronie's patients, from vascular dysfunction at the plaque site or psychological distress.
Treatment at KIMS
Treatment is selected according to disease phase. In the active phase (curvature still changing), medical management aims to slow progression. In the stable phase, definitive interventions — intralesional injection or surgical correction — can restore function.
Active phase — Oral pentoxyfilline & Vitamin E
Oral pentoxyfilline — an anti-fibrotic agent that reduces TGF-beta-driven collagen deposition. Evidence: modestly reduces plaque size and curvature progression in the active phase. Well-tolerated. Vitamin E — antioxidant — widely used, modest evidence base. Often combined with pentoxyfilline.
Active phase — Traction therapy
Penis extender devices. Mechanical stretching of the penis for several hours daily has evidence for reducing curvature and preventing further shortening in the active phase. Requires patient commitment to daily use for 3 to 6 months.
Stable phase — Collagenase (Xiaflex) injection
Collagenase Clostridium histolyticum (CCH) — the only pharmacological treatment with robust RCT evidence (IMPRESS I and II trials) for established Peyronie's disease. Collagenase is injected directly into the plaque, degrading the excess collagen. Requires a series of injections 6 weeks apart, combined with modelling (manual bending of the penis in the direction opposite to the curvature under local anaesthetic). Reduces curvature by an average of 17 degrees in clinical trials. Most effective for dorsal plaques and curvatures between 30 and 90 degrees.
Stable phase — Nesbit plication
Sutures placed on the side opposite the plaque, correcting curvature by shortening the longer side. Simple, reliable, low complication rate. Some further shortening.
Stable phase — Plaque incision/excision with grafting
The plaque is incised or excised and a graft (pericardium, dermis, or synthetic material) patches the defect. Corrects curvature without further shortening. Best for severe curvature with hourglass deformity.
Stable phase — Penile prosthesis implantation
For men with both Peyronie's disease and severe erectile dysfunction not responding to PDE5 inhibitors. The prosthesis straightens the penis mechanically during inflation.
Surgery for Peyronie's disease should only be performed after the curvature has been stable for at least 3 months (end of the active phase). Operating during the active phase risks further plaque formation and curvature recurrence. At KIMS, a minimum of 3 months of documented stable curvature is confirmed before any surgical planning.

Frequently Asked Questions — Peyronie's Disease
Without treatment, Peyronie's disease stabilises in most men after the active phase (6 to 18 months) — the curvature does not worsen further but does not spontaneously reverse to normal in the majority of cases. Spontaneous resolution of curvature occurs in approximately 12% of men. For the remainder, treatment — collagenase injections or surgery — is required to correct the curvature. Early intervention during or just after the active phase gives the best outcomes. The condition does not progress indefinitely; it stabilises.
Yes — ED affects 30 to 50% of Peyronie's patients. The mechanisms: direct vascular damage at the plaque site (reducing arterial inflow to the affected area of the corpus), venous leak (the inelastic plaque cannot compress venous outflow during erection — a veno-occlusive mechanism), and psychological ED from performance anxiety and relationship distress caused by the curvature. In men with both Peyronie's disease and ED not responding to PDE5 inhibitors, a penile prosthesis simultaneously treats both conditions.
Mild curvature (below 30 degrees) that does not interfere with sexual activity and does not cause distress may not require active treatment — monitoring with conservative measures is appropriate. Moderate curvature (30 to 60 degrees) is the range where collagenase injections are most effective and where surgical correction is clearly beneficial. Severe curvature (above 60 degrees) or curvature preventing penetration almost always requires surgical correction. The decision is guided by the functional impact and the patient's goals, not the degree alone.
There is a genetic predisposition — Peyronie's disease is associated with HLA-B7 antigen and with Dupuytren's contracture (a fibrotic condition of the palm causing finger contracture). Men with a first-degree relative with Peyronie's or Dupuytren's disease have a higher risk. The genetic component predisposes to abnormal fibrotic healing — the trigger is still traumatic micro-injury to the tunica during sexual activity. It is not a sexually transmitted condition.
