Good In. Bad Out. A Healthy Gut in a Polluted World is Key to Fertility | Your Fertile Health

Plastic exposure is no longer just an environmental story. It is a biological one. Emerging human studies now detect micro- and nanoplastics inside the placenta and even within the amniotic fluid, the very spaces where early development unfolds. Across animal models, these particles and their associated chemicals disrupt ovarian reserves, damage sperm development, alter placental function, and even create transgenerational effects. In this presentation, Dr. Matt Dunn, PhD, unpacks the growing scientific signal linking plastic exposure to reproductive health. He explains why biology does not meet plastic as a single substance but as a blended mix of particles and chemical additives - each capable of interacting with sensitive tissues. He also outlines why a gut-first strategy is one of the most biologically grounded ways to reduce internal exposure today. This session offers a clear, evidence-based narrative for clinicians, wellness practitioners, and anyone seeking to understand how everyday plastic exposure may be shaping fertility, pregnancy, and long-term health.

In this episode, you will:

• Understand what “plastic exposure” truly means, including the blend of particles and chemical additives that enter the body and why reproductive tissues are uniquely sensitive to them.
• Review the latest human evidence showing microplastics detected in the placenta and amniotic fluid, and what these findings signal for fetal development.
• Examine consistent mechanistic patterns from animal studies linking micro and nanoplastics to disrupted ovarian function, impaired sperm production, altered placental metabolism, and cross-generational effects.
• Connect plastics and their associated chemicals (phthalates, bisphenols, and other additives) to documented changes in fertility and pregnancy outcomes.
• Learn why the gut is the primary gateway for exposure and how gut-first strategies provide a practical, biologically sound way to reduce internal plastic burden.
