Doctor's Notes on Jock Itch

Jock itch is the name that refers to an itchy rash in the groin that commonly involves the inner thighs and adjacent skin, including the scrotum, in males. The most common cause of jock itch is friction, humidity, and heat. However, fungal and bacterial infections may also be present in some cases. Jock itch can occur in both men and women, but it is more common in men than in women because of the friction and humidity associated with the male genital area.

Symptoms of jock itch begin in areas of skin folds, where the skin rubs against neighboring skin. Signs and symptoms associated with jock itch include itching, skin redness, a raised red rash with sharp borders, and pimples that may occur at the edge of the rash. The irritation of the rash increases over time and can in some cases lead to breakdown of the skin.
