What Is Jock Itch?

Jock itch, otherwise called tinea cruris, is a fungal infection that usually affects men. It gives rise to rashes in the skin of the genitals, inner thighs, and buttocks. The rashes are itchy, pink or red, and mostly ring-shaped. They generally develop in the warm and most parts of the body, as it is the perfect environment for the fungus to grow.

Mold-like fungi known as dermatophytes often cause jock itch. These fungi live on human skin, hair, and nail. They are usually harmless, but due to poor hygiene and sweat, they find the perfect environment to multiply and cause infection.

Jock itch is more common in athletes, obese people, and people who sweat a lot. It is not a serious infection but can cause discomfort and irritation. This infection is treated by keeping the groin area clean and dry, and by applying antifungal powder or cream.
