Ep 411 The Hidden Link Between Mold, Inflammation, and Fertility

Could something in your home be quietly affecting your fertility? In this episode, Michelle sits down with Ariana Thacker, chemical engineer, venture capitalist, and founder and CEO of MoldCo, to explore one of the most overlooked pieces of the fertility conversation, mold toxicity. Ariana shares her own path from patient to founder, and breaks down what mold actually is, why it so often goes undetected, and how it can trigger widespread inflammation in the body. Together they unpack why some people are far more sensitive to mold than others, the genetic piece behind that sensitivity, and how this hidden inflammatory load can surface as brain fog, fatigue, irregular or painful periods, and even recurrent miscarriage. Ariana also walks through what testing and recovery can look like, and offers a grounding reminder that once you know what you are working with, there is a clear and increasingly accessible path forward. If you have been doing everything right and still feel stuck, this conversation may open a door you didn't know was there.

Key Takeaways:

• Mold is often invisible. You cannot rely on what you can see or smell, and it frequently hides in HVAC systems, crawl spaces, under flooring, and even in brand new construction.

• For many people the real issue is not the mold itself but the inflammatory response it sets off, which can ripple into hormones, cycles, energy, and mood.

• Genetics matter. Roughly one in four people carry a genetic susceptibility that makes it harder for the body to recognize and clear these toxins, which helps explain why one person in a home gets sick while another feels fine.

• Mold-related inflammation can show up in surprising ways for fertility, including irregular, heavy, or missed periods, new food sensitivities, and markers associated with pregnancy loss.

• Testing and treatment are far more affordable and accessible than they used to be, and most people improve significantly once the exposure is identified and addressed.
