What Causes Jock Itch?

Jock itch is most commonly contracted by coming into contact with clothing or towels contaminated with the fungus. The groin area provides a warm and humid environment, which encourages fungus growth.

Jock itch may also be caused by the spread of athlete’s foot fungus to the groin area by contact. Excessive perspiration can also encourage fungus growth.
