How are men decolonized & treated for yeast infection so they don't re-infect their partner?

See answer. Yeast infections are not considered sexually transmitted infections. Although yeast infections may spread from one sexual partner to the other, it's rare and in vast majority of women who have recurrent yeast infections, it has nothing to do with male partner, yeast infections primarily occur in uncircumcised men and common in diabetics. Proper hygiene and topical/oral antifungals used to treat.
