In this episode of The Human Upgrade, Host Dave Asprey talks with Dr. Ann Shippy, a board certified internal medicine physician, functional medicine practitioner, and former IBM chemical engineer, about why preconception is the most powerful window to shape lifelong health for future children. Dr. Shippy explains how fertility acts as a biological check engine light that reflects mitochondrial health, hormone balance, toxin exposure, sleep quality, and stress load long before pregnancy begins. Dave and Dr. Shippy lay out a clear roadmap for men and women to prepare their bodies months or years before conception, treating sperm and egg quality as biological time capsules that influence brain development, immune function, and long term resilience. They explore the role of environmental toxins and mold, circadian rhythm disruption, thyroid and testosterone health, targeted supplements, and when IVF makes sense versus when it bypasses essential biological intelligence. This conversation reframesfertility as a cornerstone of longevity, human performance, and generational health, offering practical insight for anyone who wants healthier kids and a stronger biological future.
This episode lays out the blueprint for having healthier children later in life by treating preconception as the most important window for human health. You’ll learn why fertility is not just about getting pregnant, but about building the biological foundation that shapes a child’s brain development, metabolism, immune function, and long term resilience. This conversation reframes infertility as a meaningful signal to pause, repair, and prepare, instead of something to override or rush past.

Dr. Ann Shippy is a board-certified internal medicine physician, certified functional medicine practitioner, and a leading expert in preconception health and fertility optimization. A former IBM chemical engineer, she brings a rare systems-based and data-driven approach to uncovering the root causes of infertility, chronic disease, and hormonal dysfunction. Through her Austin-based medical practice, she has helped men and women restore fertility naturally and conceive healthy children well into their 40s using advanced lab testing, precision supplements, and targeted functional medicine strategies.
Together, Dave Asprey and Dr. Shippy explore why childhood illness and infertility are rising at the same time, and how environmental toxins, mold exposure, microbiome imbalances, sleep disruption, and chronic inflammation undermine fertility in both men and women. They discuss the role of mitochondria, circadian rhythms, thyroid health, testosterone, and epigenetics in reproductive health, and why IVF should not be the first step without addressing underlying biological dysfunction.
