Treatment of Bacterial Vaginosis in Men

Understanding Bacterial Vaginosis in Men

  • Bacterial vaginosis (BV) is not considered a condition that affects men directly, but rather a clinical syndrome in women resulting from replacement of normal vaginal flora with anaerobic bacteria 1, 4
  • Men are not typically symptomatic even when carrying BV-associated bacteria 2, 3
  • BV is associated with sexual activity, as women who have never been sexually active rarely develop BV 4, 5

Traditional Approach to Male Partners

  • According to CDC guidelines, treatment of male sex partners has not been found beneficial in preventing the recurrence of BV in women 1, 2, 3
  • The principal goal of BV therapy is to relieve vaginal symptoms and signs in women, not to prevent transmission to men 2
  • Historically, preventing transmission to men has not been considered a goal of therapy 3

Important Caveats

  • It's essential to distinguish BV from other conditions like candidiasis, which requires antifungal treatment rather than antibiotics 6, 7
  • The traditional standard of care based on older guidelines does not recommend male partner treatment 1, 2, 3

Treatment Considerations

  • Men should avoid alcohol during treatment with metronidazole and for 24 hours afterward 2, 3
