Jock Itch

  • Rash of the groin and inner, upper thighs caused by a fungus
  • Much more common in males than females


  • Pink-red, scaly rash on inner thighs near groin. Often, starts in the groin crease. Then, spreads slowly downward.
  • In boys, the rash does not involve the penis or scrotum.
  • Rash is most often the same on both inner thighs.
  • Rash is itchy, but not painful.


  • Jock itch is caused by a fungus. Often, this is the same fungus that causes athlete's foot.
  • It can come from a towel used to dry the feet and then the groin.
  • The fungus can only grow in warm, damp skin. Sweating a lot and wearing damp underwear raises the chance of getting it.
  • Called jock itch because it occurs mostly in teen males who play sports.

How to Prevent Jock Itch From Coming Back

  • Keep the groin area clean and dry. Reason: the fungus can't grow on dry, normal skin.
  • Change to dry underwear after playing sports.
  • Also, avoid wearing underwear that is too tight.
  • Bring gym clothes home. Wash at least weekly.
  • If you have athlete's foot, use a separate towel for the feet.
