The Overlooked Factor in Fertility: Your Vaginal Microbiome
I’ve heard so many stories of women struggling with unexplained fertility issues. Women who have gone through multiple miscarriages, endured round after round of testing—hormones, blood work, ultrasounds—only to be told that everything looks "normal."
Some are even told, "You're just unlucky. Try again."
But what if it’s not luck? What if something is being overlooked?
One area that is rarely considered, even by fertility specialists, is the health of the vaginal microbiome. While there’s plenty of discussion around egg quality, ovulation tracking, and uterine lining, the microbial environment of the vagina—the very first place sperm encounters—barely gets a mention.
Yes, Your Vaginal Has a Microbiome
Just like your gut and mouth, your vagina has its own ecosystem of bacteria that help maintain balance and support reproductive health. This delicate microbiome plays a crucial role in:
Protecting against infections
Regulating vaginal pH
Supporting cervical mucus production, which is essential for sperm survival
Reducing inflammation
Enhancing implantation and pregnancy success
A healthy vaginal microbiome is predominantly made up of beneficial bacteria, primarily Lactobacillus species, which produce lactic acid to maintain an optimal pH (around 3.8–4.5). This acidic environment prevents harmful bacteria and pathogens from taking over.
But when this balance is disrupted? That’s when problems arise— usually silently.
What Happens When the Vaginal Microbiome is Out of Balance?
Vaginal dysbiosis, or an imbalance in the vaginal flora, can contribute to:
Recurrent miscarriages – Studies show that a lack of Lactobacillus dominance is linked to an increased risk of miscarriage.
Painful sex or urination – Chronic irritation and inflammation can cause ongoing discomfort.
Chronic BV or yeast infections – Opportunistic bacteria or fungi can thrive without enough beneficial bacteria.
Unexplained infertility – A vaginal microbiome dominated by harmful bacteria may reduce implantation rates and make conception more difficult.
The Silent Issue: Why You Might Not Notice It
Many assume that vaginal infections or imbalances—like BV, fungal overgrowth, or even STIs—always come with obvious symptoms. But that’s not always the case.
Some women experience itching, burning, or unusual discharge, while others have no noticeable symptoms at all. This means that a disrupted vaginal microbiome could be affecting fertility without any clear signs.
It’s frustrating to think that many fertility specialists don’t even consider testing for vaginal microbiome imbalances—even when all the "standard" tests come back normal.
That’s why comprehensive testing is essential when investigating unexplained fertility struggles, recurrent miscarriages, or ongoing vaginal discomfort.
How to Support a Healthy Vaginal Microbiome
The good news is that there are natural, evidence-based ways to nurture and restore balance to the vaginal microbiome.
1. Rethink Your Diet
Reduce sugar intake, as excess sugar feeds harmful bacteria and yeast.
Eat fermented foods like kimchi, sauerkraut, miso, and yoghurt to naturally boost Lactobacillus.
Increase fluid intake and consume unsweetened berry juices, which contain antimicrobial properties that support vaginal health.
2. Be Mindful of Hygiene and Lifestyle
Wear breathable, cotton underwear and avoid tight-fitting synthetic fabrics that trap moisture.
Wash with water only—your vagina is self-cleaning, and soaps or washes can disrupt its delicate pH balance.
Avoid douching or using scented feminine hygiene products, as they can kill beneficial bacteria.
3. Support Your Vaginal Microbiome with the Right Probiotic
Not all probiotics are created equal. Look for strains like Lactobacillus crispatus, L. rhamnosus, and L. reuteri, which specifically support vaginal microbiome health.
4. Support Gut Health to Improve Vaginal Health
Address intestinal dysbiosis and leaky gut, as gut imbalances can contribute to chronic vaginal infections and inflammation.
Herbal medicine can help restore balance—botanicals like chamomile, marshmallow root, and calendula support gut and vaginal mucosal integrity.
5. Drink Green Tea Daily
Green tea contains polyphenols, which help support beneficial bacteria and reduce inflammation.
Could Your Vaginal Microbiome Be Affecting Your Fertility?
If you’ve experienced recurrent miscarriage, unexplained infertility, or ongoing vaginal discomfort—and all the standard tests have come back "normal"—it may be time to look deeper.
I offer comprehensive vaginal microbiome testing that provides a detailed breakdown of your unique microbial profile. This allows us to assess imbalances and tailor a plan to support optimal fertility and vaginal health.
If you’re curious about testing, reach out. I can also provide a sample report so you can see exactly what’s included.
You don’t have to suffer in silence, and you don’t have to accept “bad luck” as an answer. There is always another layer to explore.
