Hi, and thanks for your query on eHealth forum!

Bad vaginal odor is commonly caused by vaginal infection or inflammation (Vaginitis) or cervical inflammation or infection (cervicitis). Both vaginitis and cervicitis can be caused by sexually transmitted diseases (STDs), such as gonorrhea and Chlamydia. Vaginal yeast infection or thrush and bacterial vaginosis (BV) are the other causes. In BV there is a distinct fishy odor. To treat vaginal odor you have to first find the cause.

A fishy smell in urine comes from bacterial vaginosis. Bacterial vaginosis is usually caused by Gardnerella vaginalis bacteria or a combination of bacteria. A decrease in the good bacterial flora (lactobacillus) and an increase in infection causing bacterial is the cause. It is not clear how the infection comes. It's not thought to be a STD as women who have not had sex can also get it. Vaginal douching, new or multiple sexual partners and smoking are thought to contribute towards the vaginosis. Diagnosis is generally by a wet mount slide showing the presence of ‘clue cells’.

Bacterial vaginosis can affect the male partner but not in the same way as it affects the female. This is because the male genitals do not have an area like the vagina which can house this infection. Men can carry traces of these bacteria in the urethra and if they multiply it can re-infect the woman.Treatment is usually by antibiotics for both partners. Generally it is treated by metronidazole given to both partners to completely eliminate the disease and to be doubly on the safe side. Although not termed as an STD yet, it is advisable to use a condom until the Bacterial Vaginosis is eliminated totally from the body.

Please consult your gynecologist regarding this. You will need a STD panel, vaginal swab tests and PAP smear. Hope this helps. Take care!
