Bacterial vaginosis isn’t considered a sexually transmitted infection in the traditional sense, but sexual activity can influence its development and transmission between partners, especially female partners.
The complex relationship with sex: BV results from an imbalance of vaginal bacteria rather than infection with a specific pathogen. However, sexual activity can disrupt the vaginal microbiome and introduce new bacteria that trigger this imbalance.
New research findings: Recent studies show that female partners of women with BV have higher rates of the condition, suggesting possible transmission of bacterial communities between women. Male partners typically don’t carry the same vaginal bacteria types.
How sex influences BV: New sexual partners can introduce different bacterial strains that disrupt existing vaginal flora balance.
Frequency of sexual activity may increase BV risk, possibly due to repeated pH changes from semen exposure.
Certain sexual practices like oral sex can introduce mouth bacteria to the vaginal environment.
What this means for couples: Male partners generally don’t require treatment since they don’t typically harbor the anaerobic bacteria that cause BV. Treating male partners hasn’t been shown to prevent BV recurrence.
Female partners may benefit from evaluation and treatment if one partner has recurrent BV, though more research is needed on optimal management strategies.
Other risk factors matter more:
- Douching (significant risk factor)
- Multiple or new sexual partners
- Smoking
- Natural hormonal changes
Prevention strategies:
- Avoid douching completely
- Use barrier methods with new partners
- Practice good hygiene without over-cleaning
- Consider probiotics to support healthy vaginal bacteria
The bottom line: While BV isn’t a classic STI, sexual factors can influence its development. Focus on maintaining healthy vaginal flora rather than viewing it as an infection that requires partner treatment in most cases.
If you’re experiencing BV symptoms like unusual discharge or fishy odor, ChatRx can help diagnose your condition and prescribe appropriate antibiotic treatment.
