Evidence for men carrying Gardnerella vaginalis in the urethra

An old study looked into Gardnerella vaginalis in the urethra of 430 men who attended a sexual health clinic, with 11 found to be carrying the bacteria. Heterosexual men were far more likely to carry G. vaginalis than homosexual men. This study is very old (1982), however, and at that point biofilms were not implicated.

In another study, 15 men gave urine samples from which G. vaginalis was isolated. Ten of the 15 men had symptoms or signs of inflammation. Men can have G. vaginalis infections in their urethras.
