Gardnerella is usually discussed as a vaginal bacteria linked to BV.
But what happens when it’s found inside your uterus? 👀🦠
Recent research suggests Gardnerella may also be associated with:
• chronic endometritis
• microbiome imbalance
• implantation failure
• recurrent IVF failure in some patients
Especially when protective Lactobacillus levels are low.
And here’s what makes it difficult:
many women have absolutely NO symptoms.
No pain.
No obvious infection.
No abnormal scans.
Yet the uterine environment may quietly become more inflammatory, less stable, and less receptive to implantation.
Gardnerella also commonly exists within biofilms — protective bacterial communities that can make infections harder to fully eliminate and more likely to persist or return after treatment.
But fertility is never about one pathogen alone.
The real question is:
👉 what kind of environment is it creating?
