Should my partner need to be treated if I have bacterial vaginosis?

No, unless chronic. Bacterial vaginosis is not a sexually transmitted infection. That means if you have bacterial vaginosis, you will not pass it to your sexual partner. However, recurrent bacterial vaginosis infections may require that you be cultured for chlamydia and if positive your boyfirend may also need treatment.
No! Bacterial vaginosis (bv) occurs when the normal type of bacteria that live in your vagina get replaced by different types of bacteria. Bv is not sexually transmitted, but instead reflects a naturally occurring change in your vagina that enables the new bacteria to grow - hormones, pH change, recent antibiotic use, etc. Your doctor can prescribe a medication to help restore the normal bacteria.
