Penis Yeast Infection: Symptoms, Causes, Treatment & Prevention (2025 Guide)

A penis yeast infection — also known as candidal balanitis — is more common than many men realise.
It occurs when Candida yeast overgrows on the skin of the penis, especially on the glans and under the foreskin.

This complete 2025 guide explains:

• Early signs & symptoms
• What causes male yeast infections
• The best treatment options
• How to prevent future infections
• When symptoms may be something else (like an STI)

Important: This guide is for general information only. If you have pain, sores, unusual discharge, or symptoms that don’t improve with treatment, speak to a doctor, GP, or sexual health clinic.

Quick Overview: What Is a Penis Yeast Infection?

A penis yeast infection happens when Candida — a fungus that normally lives on the skin — grows too much in a warm, moist environment.
Uncircumcised men are more likely to develop it, but it can affect anyone.

Symptoms of a Penis Yeast Infection

Symptoms range from mild irritation to significant discomfort.
Common signs include:

• Redness on the head (glans) of the penis
• Itching or burning around the foreskin
• White, clumpy discharge under the foreskin
• Moist or shiny patches of skin
• Swelling of the foreskin
• Pain during sex or when retracting the foreskin
• A faint sweet scent (not always present)

If symptoms include painful ulcers, strong odour, coloured discharge, or blisters, it may not be yeast — see a doctor to rule out STIs or bacterial infections.

Causes of Penis Yeast Infections

Several factors can cause Candida to overgrow on the penis:

• Poorly controlled diabetes (high blood sugar supports yeast growth)
• Antibiotic use (reduces healthy bacteria)
• Uncircumcised men (moisture under the foreskin)
• Sex with a partner who has a yeast infection
• Tight or synthetic underwear
• Excess moisture or sweat
• Weakened immune system

How Men Get Yeast Infections From Partners

Yeast is not an STI, but it can be passed back and forth, especially if one partner has an active vaginal or penile yeast infection.

Common scenarios include:

• Sex with a partner who has thrush
• Untreated recurrent yeast infections in a partner
• Moisture and friction after sexual activity

If both partners have symptoms, both should be evaluated to prevent reinfection.

Treatment for Penis Yeast Infections (2025)

The most common treatment is an antifungal cream applied directly to the affected skin.
Mild infections often improve within 7–14 days.

1. Antifungal Creams

Creams containing clotrimazole or miconazole are widely recommended.

2. Oral Antifungal Tablets (Prescription Only)

Doctors may prescribe oral antifungals (often fluconazole) if:

• The infection is severe
• It keeps coming back
• Creams haven’t worked

These medications are not suitable for everyone, so a doctor must approve treatment.

3. Gentle Hygiene Routine

Treatment is more effective when combined with proper penile hygiene.

• Wash daily with warm water (no harsh soaps)
• Dry the area completely
• If uncircumcised, gently retract foreskin and wash underneath

Natural Remedies for Male Yeast Infections

Some natural approaches may help soothe external irritation, but they do not replace antifungal medication.

Common options:

• Coconut oil (external use only)
• Sitz baths with warm water
• Probiotic-rich foods

• Penile skin irritation
• Incorrect treatment
• Candida strain differences

When Symptoms Might Be Something Else

Yeast infections are common, but symptoms that include pain, blisters, strong odour, or coloured discharge may suggest:

• Balanitis
• Bacterial infection
• STIs (such as herpes or trichomoniasis)
• Dermatitis or eczema

If you’re unsure, a doctor or sexual health clinic can test for all these conditions quickly.

• You have painful urination
• Symptoms don’t improve after 1–2 weeks
