I kinda don't buy the concept of "reinfecting yourself". The candida albicans microorganism is present in and on our bodies all of the time. There is no way to fully eradicate it, it is always around. The key is making sure that your friendly flora have the upper hand and don't get outcompeted by the candida. I do agree with the previous poster that said maybe these shorts simply don't breathe as well and that could be tipping the balance.
Or, here's another theory... just like antibiotics and antimicrobial soap can kill your good flora and let yeast get the upper hand, is it possible that this PI chamois contains an antibacterial/antimicrobial agent? I've seen this advertised as a feature on certain shorts and garments. They claim it's to maintain freshness, but I find that most things like this end up causing me more trouble in the end.![]()
Another possibility is that you are getting a type of allergic reaction to the material in the shorts or chamois and this is causing something like contact dermatitis which could certainly precipitate a yeast infection.
