Peyronie’s Disease
What Is Peyronie's Disease?
Peyronie’s Disease (PD) is a connective tissue disorder that affects the penis, causing the formation of fibrous scar tissue (plaque) within the tunica albuginea – the thick sheath surrounding the erectile tissue. This condition leads to penile curvature, pain during erections, and can significantly impact sexual function and quality of life.
Named after French surgeon François Gigot de la Peyronie who first described it in 1743, Peyronie’s Disease affects approximately 6-10% of men, though the actual prevalence may be higher due to underreporting caused by embarrassment or lack of awareness.
What Causes Peyronie's Disease?
Primary Causes of Peyronie's Disease
Penile Trauma and Injury The most common cause of Peyronie’s Disease is trauma to the penis, which can occur during:
- Sexual intercourse (especially vigorous activity or certain positions)
- Masturbation
- Sports injuries or accidents
- Medical procedures or surgeries
When the penis is bent or injured during an erection, small tears can develop in the tunica albuginea. In some men, the healing process creates excessive scar tissue, leading to Peyronie’s Disease.
Repeated Microtrauma Many cases develop from repeated minor injuries over time rather than a single traumatic event. These micro-injuries may go unnoticed but accumulate, triggering abnormal scar tissue formation.
Genetic Predisposition Research suggests genetic factors play a role in Peyronie’s Disease development. Men with family members who have PD or related connective tissue disorders (like Dupuytren’s contracture) face increased risk.
Autoimmune Response Some evidence indicates Peyronie’s Disease may involve autoimmune processes where the body’s immune system mistakenly attacks penile tissue, causing inflammation and scarring.
Risk Factors
- Age: Most common in men 40-70, with peak incidence around age 55
- Erectile dysfunction: Men with ED are more likely to develop PD
- Connective tissue disorders: Dupuytren’s contracture, plantar fasciitis
- Diabetes: Associated with increased Peyronie’s Disease risk
- Smoking: Tobacco use contributes to vascular problems and healing issues
- Prostate surgery or radiation: May increase risk of penile scarring
- Certain medications: Beta blockers and some blood pressure medications
Peyronie's Disease Symptoms: What to Look For
Palpable Penile Plaque or Lumps One of the first symptoms is often a hard, fibrous lump that can be felt under the skin of the penis shaft. This plaque may feel like a firm band or nodule.
Penile Curvature During Erection The hallmark symptom of Peyronie’s Disease is abnormal bending of the penis when erect. Curvature can occur in any direction:
- Upward curvature (most common)
- Downward bend
- Lateral curve (to the left or right)
- Hour-glass deformity or indentation
Painful Erections Many men experience pain during erections, especially in the acute phase of the disease. Pain may be sharp, aching, or described as tightness.
Penile Shortening Loss of penile length is common, typically ranging from 0.5 to 1.5 inches. This occurs due to scar tissue contraction and can be distressing for patients.
Advanced Peyronie's Disease Symptoms
Erectile Dysfunction Approximately 50-75% of men with Peyronie’s Disease develop erectile dysfunction due to:
- Physical deformity preventing proper blood flow
- Psychological stress and performance anxiety
- Damage to erectile tissue from the disease process
- Vascular problems associated with plaque formation
Difficulty with Sexual Intercourse Severe curvature can make penetration difficult or impossible. Some men experience:
- Pain during intercourse (for themselves or their partner)
- Inability to maintain penetration
- Difficulty achieving orgasm
- Reduced sexual satisfaction
Emotional and Psychological Impact Peyronie’s Disease significantly affects mental health, causing:
- Depression and anxiety
- Loss of confidence and self-esteem
- Relationship stress and intimacy problems
- Social withdrawal and isolation
- Body image issues
