While there are numerous reasons why your boys might be giving you trouble, the most likely cause of persistent testicular itching is jock itch.
Jock itch, also referred to as ringworm of the groin, tinea cruris, or (in some circles) crotch rot, is caused by a fungus called Trichophyton rubrum. This particular type of fungus grows in warm and moist areas in the groin, inner thighs and buttocks.
Jock itch occurs more commonly among adult men and adolescent boys, and (obviously) athletes. It results from friction with the use of tight clothes combined with prolonged exposure to excessive sweating in the groin area.
Jock itch appears as a rash, redness, and scaling of the inguinal folds (front crotch zone) and may extend into the crack region. The rash usually has well defined edges.
We’ve posted one relatively mild jock itch photo here, but it’s tough to post many pictures of jock itch without possible exposing you to a lot more than you may want to see right now.
Still, when you’re trying to diagnose itchy balls a picture truly is worth a thousand words, so here’s a link to the Google image search for “jock itch.” Just make sure nobody’s going to be walking by your monitor, because it’s pretty NSFW.
Is it Contagious?
Yes. Jock itch can be contagious and spread by direct skin to skin contact and poor hygiene.
Since jock itch and athlete’s foot are caused by the same kind of fungus, it’s possible to get one from the other.
Treatment & Prevention
The good news about jock itch is that it is extremely common and very easy to treat. There’s a wide range of antifungal creams, powders, and sprays available over the counter, although a doctor can prescribe you with stronger stuff if you’ve got it real bad.
It’s also important to keep your nether regions super clean and dry during your recovery. This means showering and changing underwear frequently, especially during the more swamp-nut inducing inducing summer months.
