Ten points to anyone who can guess the medium of the artwork above! I’ll give you a hint: it’s not paint…

…drum roll…

These figures are made by carefully inoculating agar in Petri dishes with various species of bacteria (and maybe some fungi too!). After a few days, the microbes replicate and grow into these intricate, colorful designs. Isn’t that incredible?!?

This particular piece feels like the perfect visual for today’s topic: the microbiome of the reproductive tract and how it relates to fertility.

Up until 2007 (when scientists developed technology that enabled us to identify microbial species through DNA sequencing) the uterus was considered a sterile environment. We now know that’s not the case. The uterus has a resident microbial population, just like the gut. And each part of the female reproductive tract (the ovaries, uterine tubes, and vagina) has its own unique microbiome. The same is true for the male reproductive tract as well.

After discovering the monumental role the gut microbiome plays in things like immune function, hormone balance, and inflammation, researchers naturally began asking questions like:

Can vaginal bacterial and fungal populations affect your chances of getting pregnant?

Short answer: very likely.

Research suggests that the composition of the vaginal microbiome, and even the seminal microbiome, may influence fertility. Studies are showing that vaginal environments with certain bacterial profiles are associated with better pregnancy rates and time to conceive, while other bacterial compositions are correlated with infertility and poorer IVF outcomes.

And here’s the unfortunate part: unfavorable microbiomes don’t always produce symptoms. 

A typical vaginal panel tests for 10-15 microorganisms (some of the big hitters) but it unfortunately doesn’t give us an understanding of the microbiome and ‘terrain’ of the reproductive tract at large. Comprehensive testing not only identifies over 700+ microbial species but it also gives us an understanding of population composition and ‘ecosystem’ imbalances so to speak.

What This Means for Your Fertility Journey

First, it’s important to remember that fertility is complex. The microbiome is just one piece of a much larger picture that includes hormones, egg and sperm quality, anatomy, genetics, nervous system regulation, the cosmos…

In my practice, when someone is struggling to conceive, we sometimes look at the vaginal microbiome and seminal microbiome as part of a broader fertility evaluation. Testing can help us understand which bacteria and fungi are present and how to shift the environment in a way that is more supportive of conception.

For some patients, this ends up being the missing piece that helps them get pregnant.
