Toenail Fungus in Men: Why It's More Common and What to Do
Toenail Fungus in Men: Why It's More Common and What to Do
By Sylke Bommel Ā· Updated July 2026 Ā· 8 min read
Key Takeaways
- Onychomycosis, the clinical term for toenail fungus, is consistently found to be more common in men than women across population studies, even though women make up roughly half of people who seek treatment.
- Population-based studies estimate toenail fungus at around 4.3% in Europe and North America, rising sharply with age to as high as 35% in adults over 65.
- Athlete's foot is one of the biggest risk factors for toenail fungus, since the same fungus can spread from the skin to the nail bed.
- Nail fungus treatment realistically takes months, not weeks, oral courses typically run about 12 weeks, but full clear nail regrowth can take up to a year.
- Topical treatments alone tend to have lower cure rates than oral medication and require long, consistent daily use, they are best suited to mild or early cases.
Why Is Toenail Fungus More Common in Men?
Toenail fungus is consistently found to be more common in men than women across population studies, largely due to greater exposure to the conditions fungus needs to thrive.
Men are more likely to wear occlusive athletic shoes and work boots for long hours, use shared gym showers and locker rooms, and have athlete's foot, which is one of the strongest risk factors for toenail fungus since the same fungus can migrate from infected skin into the nail bed. None of this means men have inherently more vulnerable nails, it largely comes down to footwear habits and environmental exposure.
Interestingly, while men are diagnosed with toenail fungus more often overall, women make up roughly half or more of people who actively seek treatment for it, which may reflect differences in how bothered people are by visible nail changes rather than true infection rates.
How Common Is Toenail Fungus, Really?
Toenail fungus affects an estimated 4.3% of the population in Europe and North America, according to a review of population-based studies, though prevalence varies considerably depending on how a study is conducted.
Age is one of the strongest factors, prevalence in children is under 1%, while it rises to as high as 35% in adults over 65. This age-related increase reflects slower nail growth, more years of cumulative exposure to fungus, and often reduced circulation, all of which make older nails more vulnerable and slower to fully clear even with treatment.
Other risk factors include diabetes, psoriasis, a weakened immune system, and living with a family member who has toenail fungus, since it can spread within a household through shared surfaces like bathmats and shower floors.
What Causes Toenail Fungus to Take Hold?
Toenail fungus usually takes hold when the same dermatophyte fungus responsible for athlete's foot spreads from the skin into a nail, often through a small crack or area of damage at the nail edge.
Once established under the nail, the fungus is protected from many topical treatments by the nail plate itself, which is part of why nail infections are so much harder to clear than a skin infection like athlete's foot. Damaged or thickened nails, tight or damp footwear, and repeated minor nail trauma from athletic activity all make it easier for fungus to gain a foothold.
This is also why treating athlete's foot promptly matters beyond the skin itself, letting a fungal skin infection linger increases the chance it eventually spreads to a nail, where it becomes considerably more stubborn to treat.
Topical vs Oral Treatment for Toenail Fungus: What to Expect
The table below compares what the clinical evidence shows for each treatment approach.
| Topical Treatment | Oral Prescription Medication |
|---|---|
| Applied directly to the nail daily | Taken by mouth, prescribed by a doctor |
| Lower complete cure rates in trials | Higher complete cure rates in trials |
| Best for mild or early infections | Often needed for moderate to severe cases |
Many dermatologists use both together for stubborn cases, since combining approaches has shown better results than either one alone in clinical studies.
How Long Does It Actually Take to Clear Toenail Fungus?
Clearing toenail fungus realistically takes months, not weeks, and this is one of the most important things to understand before starting treatment.
Oral antifungal courses for toenails typically run around 12 weeks, but that is just the treatment period, not how long it takes to see a fully clear nail. Because toenails grow so slowly, it can take up to a year for a healthy, fungus-free nail to fully grow out and replace the affected one, even when the underlying infection has been successfully treated.
A topical starter approach, like Imperial Feet's Nail Mycosis Starter Kit, is best suited to mild, early, or maintenance-stage infections used consistently over many months, rather than something expected to visibly clear a nail in a matter of weeks. Setting realistic expectations from the start makes it much easier to stay consistent long enough for treatment to actually work.
When Should You See a Podiatrist or Doctor?
See a podiatrist or doctor if a nail infection is thick, painful, spreading to other nails, or has not improved after several months of consistent topical treatment.
Men with diabetes should have any nail changes evaluated by a professional rather than self-treating, since reduced circulation and sensation can allow minor nail problems to progress without being noticed. A doctor can also confirm the diagnosis, since not every discolored or thickened nail is fungal, and can discuss whether an oral prescription antifungal is appropriate for a more stubborn or severe case.
Because oral antifungals carry their own considerations, including possible liver monitoring, they are a decision to make with a doctor rather than something to pursue independently.
4.3%
Toenail fungus affects an estimated 4.3% of the population in Europe and North America, rising to as high as 35% in adults over 65, per a literature review in the Journal of the European Academy of Dermatology and Venereology.
Toenail Fungus Prevention and Care Checklist
- āTreat athlete's foot promptly so it does not spread to a nail
- āKeep feet dry and change socks daily
- āWear sandals in gym showers and locker rooms
- āUse a topical treatment consistently for months, not days, for mild cases
- āSee a podiatrist if a nail is thick, painful, or not improving after several months
ā ļø Note: if you have diabetes, have any nail changes evaluated by a podiatrist rather than self-treating, since reduced circulation and sensation can allow minor problems to progress unnoticed.
Nail Mycosis Starter Kit
Nail Mycosis Starter Kit is designed for mild, early, or maintenance-stage nail fungus, used consistently over several months as part of a realistic, long-term approach.

Why do men get toenail fungus more than women?
It largely comes down to greater exposure, more time in occlusive athletic shoes and work boots, more use of shared gym showers, and higher rates of athlete's foot, which is a major risk factor since the fungus can spread from skin to nail.
How long does toenail fungus treatment actually take?
Oral treatment courses typically run around 12 weeks, but because toenails grow so slowly, it can take up to a year to see a fully clear, healthy nail grow out even after the infection itself has resolved.
Can toenail fungus go away on its own without treatment?
It is unlikely to resolve on its own and tends to persist or slowly worsen without treatment. Starting treatment earlier, while the infection is mild, generally leads to better and faster results than waiting.
Do topical treatments work as well as oral medication for nail fungus?
Clinical trials generally show lower complete cure rates for topical treatments compared to oral prescription medication, though topicals are a reasonable option for mild or early infections when used consistently over many months.
When should I see a doctor about toenail fungus?
See a doctor if the nail is thick, painful, spreading to other nails, or has not improved after several months of consistent topical treatment. Anyone with diabetes should have nail changes evaluated by a professional rather than self-treating.
