Gardnerella vaginalis in the male upper genital tract: a possible source of reinfection of the female partner.

We describe a case of Gardnerella vaginalis colonization of the upper genital tract of the male partner of a woman with recurring bacterial vaginosis. G. vaginalis could not be cultured from the urethra but was cultured from semen. After treatment of the male partner with metronidazole, the woman had no more relapses of bacterial vaginosis.
