Vaginal discharge under normal circumstances is a simple way the body has of cleaning the vagina. This normal discharge can be milky white and odorless. The amount of discharge can vary depending on whether or not the woman is ovulating or on her menstrual cycle. When the normal discharge changes and begins to emit a foul odor and is accompanied by itching or burning, it may be a sign of an
. infection. The odor itself can smell like fish, chemicals, or musty depending on the problem. Commonly the 'smelly' odor is associated with vaginal infections that are due to bacteria or fungi growing uncontrollably in the vagina. This infection is called bacterial vaginosis . These bacteria and fungi are present in healthy numbers in the vagina normally but sometimes they can multiply to unhealthy numbers. Vaginal odor may also be caused by tampons, bath water or sexual contact.

There is a wide range of vaginal infections that can cause unpleasant odors.
