Yeast Infection --> Infertility?

[so-much-udder.livejournal.com]

Heyyy. I've heard that yeast infections left untreated can cause infertility? I looked it up on the internet and got conflicting results, saying it can and it can't. Does anyone know anything about this/know any good sources? How long would it have to go untreated for this to happen?

(for the record, I am treating mine but it's taking a hell of a long time...antibiotics, etc.)

Thanks!
