Although G vaginalis urinary tract infections (UTI) occur much more frequently in women than in men, the overall occurrence of G vaginalis as a causative etiology in this infection is low (< 0.6%). However, the overall frequency may be underestimated because of a lack of optimal laboratory growth conditions (eg, aerobic incubation, short anaerobic growth period, urine not properly refrigerated prior to being cultured) and absence of associated pyuria occurring in women with concomitantly positive urine cultures.

In men, infections caused by G vaginalis are uncommon. Infection of the prostate and urinary bladder have been documented, although this occurs rarely and probably arises as a result of ascending spread of the organism from the colonized urethra. Balanoposthitis from G vaginalis has also been described.
