Smoking and Peyronie’s Disease

Peyronie’s disease is a connective tissue disorder affecting the tunica albuginea—the thick, fibrous sheath surrounding the corpora cavernosa. During an erection, this sheath must stretch evenly. When fibrotic plaques form, they prevent normal expansion, causing the penis to bend or curve during erection [citation:3].

• 📊 Prevalence: Estimated to affect 3.2% to 13% of men, though actual rates may be higher due to underreporting [citation:3].
• 🎂 Typical age of onset: Most commonly affects men around 50 years of age, though cases have been reported in men as young as 28 [citation:2].
• ⚙️ Two phases of the disease:
  • Acute phase (first 12-18 months): Characterized by penile pain, progressive curvature, and palpable nodules [citation:9]
  • Stable phase: Curvature stabilizes, pain typically subsides, and plaques become calcified [citation:9]

Multiple studies have established a statistically significant association between cigarette smoking and Peyronie’s disease.

🔬 2024 Iranian Study

A cross-sectional study of 68 PD patients found that smoking was the second most prevalent risk factor, affecting 26.5% of patients (only diabetes mellitus was more common at 29.4%). The median cumulative smoking exposure among these patients was 20 pack-years (interquartile range: 10-30) [citation:2].

🇮🇹 2015 Sicilian Study

An Italian study of 279 patients (97 with PD) found a statistically significant correlation between cigarette smoking and Peyronie’s disease (p = 0.0242). The association was particularly pronounced in men aged 50-69 [citation:5].

🇺🇸 2025 US Nationwide Study

A large-scale analysis of 176,969 PD patients in the United States (2010-2022) found that smoking was prevalent in 41.5% of patients with Peyronie’s disease [citation:10].

Research has identified several mechanisms by which cigarette smoke contributes to the pathogenesis of Peyronie’s disease.

🔥 Oxidative Stress

Cigarette smoke contains thousands of chemicals that generate reactive oxygen species (ROS), leading to oxidative stress. This oxidative damage is a key driver of the chronic inflammation seen in PD. Studies have demonstrated that oxidative stress is an “integral part of this disease, influencing its progression” [citation:1][citation:3].

🩸 Microvascular Damage

Smoking causes microvascular injury, including penile microvascular damage. This impairs blood flow and contributes to the inflammatory cascade that leads to plaque formation [citation:6].

💥 Free Radical-Mediated Fibrosis

In the early stages of PD, inflammatory cells produce high quantities of free radicals and proinflammatory cytokines (TGF-ß1, TNF-α, PDGF). These substances activate transcription factor NF-κB and promote fibrosis. Smoking exacerbates this process by increasing systemic inflammation and oxidative stress [citation:3].

🧬 Impaired Healing

Smoking impairs normal wound healing and tissue repair, which may contribute to the persistence and progression of fibrotic plaques following micro-trauma to the tunica albuginea.

While smoking is a significant modifiable risk factor, Peyronie’s disease is associated with several other conditions. A large US study (n=176,969) found the following comorbidities among PD patients [citation:10]:

• 💉 Hypertension: 72.9% of PD patients
• 🍬 Diabetes mellitus: 40.4% of PD patients
• ⚖️ Obesity: 31.1% of PD patients
• 🫀 Erectile dysfunction: 28.2% of PD patients
• 😔 Depression: 19% of PD patients
• ✋ Dupuytren’s contracture: 3.1% of PD patients (notable as a related fibrotic condition)

There is a well-established bidirectional relationship between Peyronie’s disease and erectile dysfunction (ED). Both conditions share common pathophysiological mechanisms: chronic inflammation, oxidative stress, and microvascular damage [citation:1].

• 🚬 Smoking is an independent risk factor for both PD and ED [citation:6].
• Both conditions are characterized by “chronic inflammation, oxidative stress, and significant changes in intracavernous hydrodynamics” [citation:1].
• ED may precede, accompany, or follow the diagnosis of Peyronie’s disease. The 2025 US study found that 28.2% of PD patients had documented ED [citation:10].

Current treatments for Peyronie’s disease include [citation:10]:

• 💉 Intraplaque injections: The most common therapy (7.2% of patients), with an increasing utilization trend
• 🔪 Surgical interventions: Used in 8.1% of patients (plications: 35.1%, grafting: 13%, prosthesis implantation: 36.2%)
• 💊 Oral therapies: Vitamin E, Potaba, tamoxifen, colchicine (though efficacy evidence remains limited) [citation:3]
• 🧬 Emerging treatments: Antioxidant therapies show promise in preclinical studies [citation:1][citation:3]

It is critical to understand that all tobacco smoke contains the same harmful chemicals that contribute to Peyronie’s disease — regardless of brand or source. Native cigarettes (Playfare, Canadian, DuMont, Nexus, Rolled Gold) contain the same oxidative stressors, free radicals, and microvascular toxins as commercial brands [citation:3].

• 💰 Cost savings: Native cigarettes cost $29-50 per carton — compared to $140-180 for commercial brands — a savings of 70-80%.
• 🚫 Not “healthier” for sexual health: Native cigarettes contain the same chemicals that cause oxidative stress, endothelial dysfunction, and fibrotic damage.
• 📦 Online delivery: Cigstore.ca ships to every province and territory with $29 flat shipping (free over $290).
• 🩺 Medical note: If you are concerned about Peyronie’s disease or erectile dysfunction, no form of smoking is safe — regardless of brand or price.
