Clinical Definition

Jock itch is a common dermatophyte infection affecting the groin area.  It is most common in adolescent males.


In Our Own Words

Jock itch is a type of fungal infection similar to ringworm. It can be found around the groin and upper inner thigh. Dermatophyte fungi like to live on moist areas of the skin, such as where the skin folds, so it is important to keep the groin area clean and dry.

 

Jock itch can affect anyone. However, it is most common among young men, those with supressed immune systems, those who use communal baths or locker rooms and those involved in contact sports. It can be treated with topical antifungal medications.
