Can condoms cause a yeast infection?

No.: Condoms come out of the package sterile, they contain no bacteria, viruses, or yeast. A condom should only be used once of course!

No: No condoms do not cause yeast infections.

Highly unlikely: Unless the condom had been open some time & become contaminated, highly unlikely that it could cause a yeast problem. Remote possibility: if condom had spermicidal agent on it, that may have somehow upset the balance between yeast and normal bacteria in the vagina, but have never seen that reported before.
