Most women who experience vaginal odor have no idea what causes it, much less how to get rid of it. Enzara is said to eliminate vaginal odor by destroying millions of harmful odor causing bacteria before odors occur. See for yourself.
Most (95%+) vaginal odor is caused by an infection called 'gardnerella'. While this infection can be passed between partners, it is not a sexually transmitted disease (STD). But women who have never had sexual intercourse can be affected as well.
This is a good PDF brochure that talks about bacterial vaginosis (the odor-causing condition) and explains that many women self-treat their presumed yeast infections unaware of the more serious condition they may be experiencing.
