Jock itch is a skin infection caused by a fungal overgrowth that affects the groin, upper thighs, and buttocks.
The scientific name for the infection is tinea cruris. It's called jock itch because it typically affects men and spreads in locker rooms among male athletes. It may also be known as "jock rot", "crotch itch", or "gym itch."
The symptoms of jock itch include:

Jock itch is caused by an overgrowth of microscopic skin fungi known as dermatophytes. We all have these fungi living on our skin in small amounts — they make up a healthy skin microbiome.
However, the warm, dark, and moist environment in the groin and inner thigh area allows the fungus to grow out of control. When this happens, it may cause infection in susceptible people. It's also triggered by using damp towels and wearing sweaty underwear, jockstraps, and sports cups. Plus, if you have a fungal infection elsewhere, you can spread it to your groin if you aren't fastidious with hygiene.
The following factors may also make you more likely to experience a jock itch infection:
While jock itch can feel unbearable, it is easy to prevent and treat — provided you know how to address it correctly.
If you're wondering "is jock itch contagious" or "how long does jock itch last" — you've come to the right place!
At WeatherWell, we've compiled some of the most common FAQs about jock itch.
Jock itch is a flat, itchy rash that develops in the skin folds and on the sides of the groin. It may become ring-shaped and spread outwards to the upper thigh and buttocks. The borders of the rash are well-defined, raised, and red, while the inner area may turn brown and become flaky. You may experience small jock itch blisters that develop around the border of the rash.
It's uncommon to see jock itch on the shaft of the penis or scrotum in men or the vulva in women.
A jock itch smell is given off by the infection-causing fungi. It's described as yeasty or sour. If your jock itch is associated with poor personal hygiene, there may be a musty odor from sweat and bacteria accumulating.
Regularly showering, changing clothes, and using an antifungal wash in the area can help to clear up the jock itch smell.
The fungal infection that causes jock itch is contagious and spreads when in close contact with someone who has it. You can catch it when sharing towels and clothes or during sexual contact with an infected person.
Jock itch is sometimes talked about as if it only affects athletes and men. So, can women get jock itch?
Yes, jock itch affects both genders. It's less common in women because they don't have as many sweat glands or as much friction in the groin area as men. Women may get the rash under the breasts, where sweat accumulates.
Unfortunately, jock itch won't resolve easily on its own. How long jock itch lasts depends on when you seek treatment. With treatment, it clears up within 2-4 weeks. Without treatment, jock itch can linger for months.
Many people do everything to avoid the embarrassment of going to a doctor, including looking up pictures of jock itch. But consulting a doctor for a diagnosis can give you peace of mind and ensure you get treatment.
The doctor will ask about your hygiene habits and examine the rash. Usually, they can identify the condition by sight and prescribe the best jock itch cream. In some cases, your doctor may take a skin culture or biopsy.
Jock itch is a mild condition that can be treated at home with antifungal cream, good hygiene, and lifestyle changes.
There are several treatment options available over the counter (OTC) and on prescription.
The most common and effective jock itch medications and remedies include:
Your doctor may suggest using a combination of an antifungal body wash, an antifungal ointment, and a jock itch powder for best results.
The jock itch healing stages can feel slow when you're dealing with this type of rash. In the early stages, itching and skin irritation stop quickly with treatment. Next, your skin will flatten out as jock itch blisters and the raised rash heal. The redness will turn a darker color.
Skin discoloration may persist for a few weeks but will fade with time.
However, don't stop treatment as soon as the itching stops. Always complete your course of treatment as advised by your doctor or pharmacist. Even if you have the best jock itch cream, it won't heal if you don't use it consistently and correctly!
If you're tired of getting a rash on your groin every time summer rolls around, there are tips you can use to prevent it before it starts.
Wear loose-fitting underwear and pants that don't chafe your thighs and groin area during exercise. Look for clothes made from breathable fabric like cotton. Men may benefit from wearing boxers instead of briefs.
Good personal hygiene is crucial to prevent fungal skin infections from developing.
A sweaty groin — from the summer heat, wearing tight clothes, or engaging in intense exercise — is the main culprit behind jock itch.
These are our best tips for keeping the area dry:
If your jock itch won't go away despite using jock itch antifungal cream and seeing your doctor, it may have become treatment resistant. Your doctor may prescribe you oral antifungal medications.
You may need a skin biopsy if symptoms don’t resolve within a month of using jock itch medication.
Please seek medical attention if your groin rash:
Jock itch is a common fungal skin infection that usually strikes in summer, causing redness and itching in the groin. It affects both men and women and can spread from one person to another.
