Risk factors
By Mayo Clinic staffThe organisms that cause jock itch thrive in damp, close environments. Warm, humid settings that promote heavy sweating — thus washing away fungus-killing oils, making the skin more permeable and more prone to infection — favor its spread.
You're at greater risk of jock itch if you:
- Are a man, although women can also get the condition
- Wear tight underwear or athletic supporters that aren't washed after each use
- Are obese
- Sweat heavily
- Have an impaired immune system
- Have atopic dermatitis, a chronic, inherited skin disease characterized by itchy, inflamed skin
