Could Your Microbiome Influence Fertility and How Your Supplements Work? with Dr. Mark Ratner

12.11.2026 · 38 Min.

Shownotes

Could your vaginal microbiome affect implantation and IVF success? And could the bacteria in your gut influence how your body responds to fertility supplements?

These are important questions, and we're learning more about how the microbiome may play a role in reproductive health. I'm joined by returning guest Dr. Mark Ratner, Chief Science Officer at Theralogix, to talk about the latest research connecting the microbiome, fertility, and NAD+. We discuss vaginal and endometrial microbiome testing, probiotics for both women and men, and the differences between the NAD+ precursors NR and NMN. I also ask Mark what this emerging science means for patients, how we can use this information in fertility care, and where we still need more research.

In this episode, we cover:

  • The differences between the gut, vaginal, endometrial, and seminal microbiomes, and how each may influence reproductive health.

  • Why Lactobacillus dominance matters for vaginal health, and how antibiotics and estrogen can affect the vaginal microbiome.

  • The different options for vaginal microbiome testing, when I recommend testing for my patients, and how endometrial testing with EMMA is different.

  • What we know about oral and vaginal probiotics and their potential impact on implantation and IVF outcomes.

  • What emerging research tells us about probiotics for men with low sperm counts or other abnormal semen parameters.

  • Theralogix's TreBiome synbiotic and the science behind OvaNAD+'s combination of two NAD+ precursors, NR and NMN.

  • The differences between oral NAD+ precursors and NAD+ infusions, when to consider supplementation before fertility treatment, and why we need to distinguish promising research from proven results.
