Transmission of Gardnerella vaginalis

The exact mechanism of how GV is transmitted is not well established. However, research shows that transmission is strongly associated with sexual activities, supported by an increased risk of BV with higher number of sexual partner, not using a condom. GV from the male urethra may act as a source of GV infection to their female partners.

Prevention

The transmission of GV can be prevented by using condoms correctly and consistently during sex.
