Fungal skin infection
Jock itch is a fungal skin infection caused by a type of fungus called dermatophyte. Dermatophytes are common fungi that live on the skin of humans and animals. They feed on keratin, a protein found in the skin, hair, and nails.
- Athlete's foot
Jock itch is closely related to athlete's foot, another common fungal skin infection. Athlete's foot typically affects the feet, while jock itch affects the groin and inner thighs. Both infections are caused by dermatophytes.
- Ringworm
Ringworm is another type of fungal skin infection that can affect the groin area. Ringworm is characterized by a red, circular rash that may be itchy or painful. Ringworm is also caused by dermatophytes.
- Tinea versicolor
Tinea versicolor is a common fungal skin infection that causes light or dark patches on the skin. Tinea versicolor is not usually itchy, but it can be unsightly. Tinea versicolor is also caused by dermatophytes.
- Candidiasis
Candidiasis is a fungal infection caused by a type of yeast called Candida. Candida is a common fungus that lives on the skin and in the body. Candidiasis can cause a variety of skin infections, including jock itch. Candidiasis is more common in people with weakened immune systems.
Jock itch is usually not a serious condition, but it can be uncomfortable and embarrassing. There are a number of effective treatments available for jock itch, including over-the-counter antifungal creams and lotions. In some cases, prescription medication may be necessary.
Red, itchy rash
The most common symptom of jock itch is a red, itchy rash. The rash may be mild or severe, and it may spread to other areas of the body, such as the buttocks and thighs.
- Itching
The rash caused by jock itch is often very itchy. The itching can be mild or severe, and it may be worse at night. Scratching the rash can irritate it and make it worse.
- Redness

Groin and inner thighs
Jock itch most commonly affects the groin and inner thighs. This is because these areas are warm, moist, and dark, which creates an ideal environment for the fungus that causes jock itch to thrive.
- Friction
The groin and inner thighs are also areas that are prone to friction. Friction can irritate the skin and make it more susceptible to infection. This is why jock itch is more common in athletes and other people who sweat a lot.
- Moisture
The groin and inner thighs are also areas that are prone to moisture. Moisture can soften the skin and make it more susceptible to infection. This is why jock itch is more common in hot and humid weather.
- Tight clothing
Wearing tight clothing can also increase the risk of jock itch. Tight clothing can trap moisture and heat against the skin, creating an ideal environment for the fungus that causes jock itch to thrive.
- Poor hygiene
Poor hygiene can also increase the risk of jock itch. Not showering or changing clothes regularly can allow the fungus that causes jock itch to grow and spread.
There are a number of things you can do to prevent jock itch, including wearing loose-fitting clothing, showering or bathing regularly, and keeping the groin and inner thighs dry. If you do develop jock itch, there are a number of effective treatments available, including over-the-counter antifungal creams and lotions. In some cases, prescription medication may be necessary.
Spread through contact
Jock itch can be spread through contact with an infected person or object, or through contact with contaminated clothing or towels.
- Direct contact
Jock itch can be spread through direct contact with an infected person. This can happen during skin-to-skin contact, such as during sports or other physical activities. It can also happen if you touch an infected person's clothing or towels.
- Indirect contact
Jock itch can also be spread through indirect contact with an infected person or object. This can happen if you touch something that has been contaminated with the fungus that causes jock itch, such as a towel, a shower floor, or a gym mat.
- Sharing personal items
Sharing personal items, such as towels, clothing, and razors, can also spread jock itch. This is because the fungus that causes jock itch can live on these items for long periods of time.
- Public places
Jock itch can also be spread in public places, such as swimming pools, locker rooms, and gyms. This is because the fungus that causes jock itch can survive in warm, moist environments.
There are a number of things you can do to prevent the spread of jock itch, including keeping the groin and inner thighs clean and dry, avoiding contact with infected people or objects, and not sharing personal items. If you do develop jock itch, it is important to wash your hands thoroughly after touching the infected area and to avoid scratching the rash.
Common in athletes
Jock itch is more common in athletes than in the general population. This is because athletes are more likely to sweat, which creates a warm, moist environment that is ideal for the fungus that causes jock itch to thrive. In addition, athletes are more likely to come into direct contact with other people's sweat and skin, which can increase the risk of spreading jock itch.
- Sweating
Athletes sweat more than the general population. This is because they are more likely to engage in strenuous activity, which causes the body to produce more sweat. Sweat creates a warm, moist environment that is ideal for the fungus that causes jock itch to thrive.
- Direct contact
Athletes are more likely to come into direct contact with other people's sweat and skin. This can happen during sports or other physical activities. It can also happen in locker rooms and showers. This increases the risk of spreading jock itch.
- Sharing personal items
Athletes are more likely to share personal items, such as towels and clothing. This can also increase the risk of spreading jock itch. This is because the fungus that causes jock itch can live on these items for long periods of time.
- Tight clothing
Athletes often wear tight clothing. This can trap moisture and heat against the skin, creating an ideal environment for the fungus that causes jock itch to thrive.
There are a number of things that athletes can do to prevent jock itch, including wearing loose-fitting clothing, showering or bathing regularly, and keeping the groin and inner thighs dry. Athletes should also avoid sharing personal items and should not walk barefoot in public places, such as locker rooms and showers.
Hot and humid weather
Jock itch is more common in hot and humid weather. This is because the fungus that causes jock itch thrives in warm, moist environments. In addition, people are more likely to sweat in hot and humid weather, which can create a warm, moist environment that is ideal for the fungus to grow.
- Warmth
The fungus that causes jock itch grows best in warm environments. This is why jock itch is more common in hot weather.
- Moisture
The fungus that causes jock itch also thrives in moist environments. This is why jock itch is more common in humid weather.
- Sweating
Sweating creates a warm, moist environment that is ideal for the fungus that causes jock itch to grow. This is why jock itch is more common in people who sweat a lot, such as athletes and people who work in hot environments.
- Tight clothing
Wearing tight clothing can trap moisture and heat against the skin. This can create an ideal environment for the fungus that causes jock itch to grow.
There are a number of things you can do to prevent jock itch in hot and humid weather, including wearing loose-fitting clothing, showering or bathing regularly, and keeping the groin and inner thighs dry. You should also avoid sharing personal items and should not walk barefoot in public places, such as locker rooms and showers.
Over-the-counter treatments
There are a number of effective over-the-counter treatments available for jock itch. These treatments typically contain antifungal ingredients that kill the fungus that causes jock itch. Some common over-the-counter treatments for jock itch include:
- Clotrimazole (Lotrimin AF, Mycelex)
- Miconazole (Desenex, Micatin)
- Terbinafine (Lamisil AT)
- Tolnaftate (Tinactin)
These treatments are typically applied to the affected area once or twice a day for two to four weeks. It is important to continue using the treatment for the full course of therapy, even if the symptoms disappear sooner. This will help to prevent the infection from coming back.
In addition to over-the-counter antifungal creams and lotions, there are also a number of other things you can do to treat jock itch at home. These include:
- Keeping the groin and inner thighs clean and dry
- Wearing loose-fitting clothing
