You know about your gut microbiome.
But nobody told you about this one.

Meet your vaginal microbiome.
A community of bacteria living in your vaginal canal that acts as your body's first line of defence — against infections, against inflammation, and against a long list of reproductive health problems most women don't connect back to it.

When it's healthy, it's dominated by Lactobacillus — bacteria that keep the environment acidic, ward off harmful pathogens, and support your immune system locally. When it's not, the imbalance is called dysbiosis. And the consequences reach further than most people realise.

Vaginal dysbiosis is linked to:

Recurrent bacterial vaginosis and yeast infections. Higher risk of STIs. Fertility problems. Pregnancy complications including preterm birth. And emerging research is now connecting it to cervical health and HPV persistence too.

What disrupts it?
Antibiotics — which wipe out Lactobacillus alongside everything else. Hormonal contraception. Vaginal douching (which the evidence is clear on: stop). Unprotected sex. Stress. And hormonal shifts across your cycle, postpartum, and into perimenopause.

What supports it?
Avoiding scented products in and around the vaginal area. Not douching. Supporting your gut microbiome, which has a direct relationship with vaginal flora. Wearing breathable fabrics. And talking to a doctor if you have recurring symptoms instead of cycling through over-the-counter treatments that mask rather than fix.

Evvy just raised $40M to expand vaginal microbiome diagnostics. The science is moving fast. It's time the conversation caught up.
