Jock itch is the common name for a fungal infection in the groin area 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. The rash may affect not only the groin, but it can involve any areas of skin that overlap, including around the anus and in the skin folds of obese individuals. Jock itch affects both men and occasionally women and is often a gateway to toenail fungus if not treated swiftly.
Although the term jock itch implies some sort of relationship with athletics, this is not necessarily true. Jock itch is particularly related to infections from microorganisms and environmental factors such as humidity and friction, which can irritate the skin. Jock itch is more common in men than in women simply because the presence of male genitalia leads to increased friction and humidity. 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. Once a fungal infection has settled in to a region of the skin, any damage to the nails will open the door for a nail fungus infection. And having to find a toenail fungus cure is considerably more difficult than simply managing a fungal infection of the skin.
