Breathing, Saliva, and pH Matter Most

A single overlooked bacteria in your mouth can alter hormones, disrupt implantation, and delay pregnancy — and most doctors never test for it.

That’s what I discovered reading a study showing that women with periodontal disease take two months longer to conceive, and that the gingivitis pathogen P. gingivalis has been found in the placentas of women who miscarried.

In this minisode, I sit down with biological dentist Dr. Staci Whitman to uncover how oral pathogens, inflammatory cytokines, and “leaky gums” impact reproductive health for both women and men. We discuss saliva, diet, mouth breathing, and why oral microbiome testing may be one of the most powerful—and overlooked—tools in fertility care.

This episode features highlights from our full conversation, which premiered August 26th, 2025. Watch the full episode here → https://youtu.be/vqcNFx4CRfk

If you care about hormones, fertility, pregnancy, or inflammation, this is a must-listen.
