Facts on Jock Itch
Jock itch is the popular name given to an itchy rash in the groin that commonly involves the inner thighs and adjacent skin, including the scrotum in males. The medical name for rash in the creases of overlapping skin is "intertrigo." Jock itch is associated with sweating, friction/abrasion, occlusive clothing, and the direct rubbing of skin on skin.

Women are actually predisposed to develop a similar condition underneath their breasts. Jock itch is most often caused simply by noninfected skin affected by friction, humidity, and heat. However, it is not uncommon for microorganisms like fungi and bacteria to simultaneously infect the skin.
