Preconception health is one of the most powerful—yet overlooked—windows for influencing a child’s lifelong wellness. While fertility is often discussed in the context of age or medical intervention, emerging research suggests that the months leading up to conception are a critical "time capsule" for epigenetic health.
In this episode of A Whole New Level, Levels Founder and CEO Josh Clemente sits down with Dr. Anne Shippy, a board-certified internal medicine physician and author of The Preconception Revolution. Dr. Shippy brings a unique, systems-based approach to fertility, moving beyond basic labs to uncover the root causes of infertility and chronic disease.
Dr. Shippy explains why the "check engine light" of infertility is often a signal of deeper metabolic or environmental imbalances—and why age isn't always the primary driver of reproductive success. Drawing on her engineering background and years of clinical practice, she walks through how toxins, mitochondrial function, and the microbiome interact to shape the health of both parents and their future children.
Along the way, the conversation explores the practical "mini-experiments" couples can run to optimize their biology—from tightening blood sugar control with CGMs to auditing the "chemical soup" of modern life. The result is an empowering framework for generational health: shifting the focus from reactive treatments to proactive, data-driven preparation.

In this episode, we cover
• The Preconception Window: Why the 3–12 months before pregnancy are a critical window for epigenetic influence
• The Engineering Approach: Applying systems-based, data-driven models to the biochemistry of the body
• Environmental Toxins: How PFAS, phthalates, and microplastics in packaging disrupt hormone health
• Sperm Health Trends: Understanding the 50% decline in sperm counts and the role of lifestyle in reversing damage
• Mitochondrial Function: Why cellular energy production is the foundation of egg and sperm quality
• IVF as a Last Resort: Why tuning up the body’s "hospitable environment" should come before invasive procedures
• The Role of Glucose: How stable blood sugar improves fertility and passes on better epigenetics to the baby
