Male lichen sclerosus: PRP-supported treatment

Lichen sclerosus is a chronic skin disorder that causes white patches, thinning, fragility, and scarring of the affected skin. In men it most commonly affects the glans, the foreskin, and sometimes the urethral meatus. Symptoms include itching, soreness, painful erections, urinary symptoms in some cases, and progressive tightening of the foreskin (phimosis).

It is not a sexually transmitted condition. The cause is not fully understood but is thought to involve immune-mediated inflammation, possibly with genetic predisposition.

Diagnosis is clinical, sometimes confirmed by biopsy. Long-term monitoring is important because there is a small but real risk of malignant change in untreated chronic lichen sclerosus, so this condition should always be managed in coordination with a dermatologist or urologist.

The mainstay of treatment is potent topical steroids (typically clobetasol) applied to affected areas. For most men, steroids control symptoms well and can prevent progression. Circumcision is curative for foreskin-confined disease in many cases and is the recommended approach for severe phimosis.

Where standard treatment falls short:

• Long-term steroid use causes skin thinning, increasing fragility and dependency
• Some men get only partial symptom control on steroids
• Once scarring has developed, steroids reduce inflammation but don't reverse the tissue change
• Symptomatic relapse after circumcision can occur in some patients

This is the niche where PRP adds value, not as a replacement for standard treatment, but as a regenerative supplement.

PRP delivers concentrated growth factors that act on three of the relevant mechanisms in lichen sclerosus:

1. Anti-inflammatory modulation: supporting the calming of chronic local inflammation that drives ongoing tissue damage

2. Tissue regeneration: supporting the repair of thinned, fragile epithelium and underlying connective tissue

3. Scar remodelling: modulating fibrotic tissue formed during chronic disease

The clinical evidence base for PRP in male lichen sclerosus is emerging: case series and small studies are encouraging but the literature is younger than for PRP in ED or Peyronie's. We are honest about this at consultation.

Treatment is always coordinated with your dermatologist or urologist: PRP is an add-on, not a replacement. Our typical approach:

• Confirm the diagnosis is established (clinical or biopsy-confirmed)
• Confirm standard treatment has been tried and where it has fallen short
• PRP applied as a series of treatments, typically 3 sessions spaced 6-8 weeks apart
• Topical anaesthetic before each session
• Follow-up at 12 weeks after the final treatment
• Joint review with your dermatologist where appropriate

Will PRP replace my steroid cream? Not usually, and not without your dermatologist's input. PRP is an add-on that may reduce the steroid dose needed over time.

Is PRP curative for lichen sclerosus? No. The aim is symptom relief, tissue regeneration, and reducing dependence on long-term steroid use. Lichen sclerosus typically requires ongoing management whatever treatment is used.

Can I have PRP before considering circumcision? Yes, many men choose to try PRP before committing to surgery. Where circumcision is clearly indicated (severe phimosis, dangerous scarring), it remains the right answer.

Is there a cancer risk, and does PRP affect it? Long-standing untreated lichen sclerosus carries a small risk of malignant change. Regular dermatological monitoring is essential whether or not you have PRP. PRP does not increase this risk and is not contraindicated.

Will the white patches go away? Often they fade and the texture improves, particularly in earlier disease. Long-established scarring is harder to reverse.
