Can you tell me how i could have trich and bv and my husband doesnt?

I'll bet he does: If you have trichomonas, chances are that he's got a few colonized in his prostate gland, where they're not producing symptoms. It's usual to treat you both. Bacterial vaginosis is the result of overgrowth of the wrong normal bacteria, not an infection by itself.

Here are some ...: While always trying to track down what may cause or be related with a disease condition, it's not always possible. But, one can say for sure is what you are represents what you have been. As to trich & BV, it has been known many men / women may get such along their life and many of them may have no symptom but just carriers. So, at times, symptoms may flare up while personal immune ability is low.
