Is Our Modern World Making Us Infertile?
Have you ever considered how our modern environment impacts our ability to have children? It’s a sobering question, and the science is pointing to some startling conclusions. In an eye-opening discussion, Dr. Andrew Huberman sits down with Dr. Shanna Swan, a leading professor of environmental medicine, to discuss a critical and urgent issue: the rapid decline in male fertility.
They explore the shocking statistic that sperm count has plummeted by over 50% in just the last 50 years and uncover the surprising role that everyday chemicals, hiding in plain sight, may play in this alarming trend.
Watch the full video below to understand the science behind this decline and what it means for our future.
Key Takeaways from the Video
For those short on time, here are the essential points from their conversation:
- A Drastic Decline: Dr. Swan’s research, which analyzed 185 studies involving nearly 45,000 men, found that sperm counts in Western countries have dropped by more than 50% in under 50 years.
- The Chemical Culprits: A class of chemicals known as “endocrine-disruptors” (EDCs) are a major cause for concern. These chemicals interfere with the body’s natural hormones.
- Common EDCs: The most discussed chemicals are phthalates (used to make plastics flexible and as a solvent in personal care products) and BPAs (used in hard plastics and the lining of food cans).
- Widespread Exposure: We are exposed to these chemicals daily through plastic food containers, cosmetics, personal care products, pesticides, and even thermal paper receipts.
Who Are the Experts?
- Dr. Shanna Swan, Ph.D.: An award-winning environmental and reproductive epidemiologist at the Icahn School of Medicine at Mount Sinai. She is the world’s leading expert on this topic and the author of the groundbreaking book, Count Down.
- Dr. Andrew Huberman, Ph.D.: A renowned neuroscientist and tenured professor at Stanford University School of Medicine. He is the host of the Huberman Lab podcast, celebrated for making complex science accessible to the public.
What Can You Do? Actionable Steps to Reduce Exposure
The information is concerning, but the good news is that awareness allows us to take action. Reducing your exposure to these chemicals is possible with a few simple, consistent changes.
In Your Kitchen:
- Ditch the Plastic: Avoid microwaving food in plastic. Use glass, ceramic, or stainless steel containers for food storage and heating.
- Can with Caution: Reduce your intake of canned foods, as many cans are lined with BPA. Look for “BPA-free” labels when possible.
- Filter Your Water: Use a high-quality water filter for drinking and cooking to remove potential contaminants.
- Choose Fresh and Organic: Opt for fresh or frozen foods over processed and packaged ones. Washing produce well, and choosing organic when you can, helps minimize pesticide exposure.
In Your Bathroom & Home:
- Read the Labels: Choose personal care products (lotions, shampoos, soaps) that are “fragrance-free” and “phthalate-free.” Fragrance is often a hidden source of phthalates.
- Simplify Your Products: Be wary of cosmetics and cleaners with a long list of synthetic chemical ingredients.
- Clean Green: Use natural cleaning products like vinegar and baking soda.
- Dust and Vacuum: EDCs can accumulate in household dust, so regular cleaning can help reduce your exposure.
- Decline the Receipt: Thermal paper receipts are often coated with BPA. Say no to a paper receipt when a digital option is available.

Conclusion: A Wake-Up Call for Our Health
The conversation between Dr. Swan and Dr. Huberman is not meant to cause panic, but to serve as a powerful wake-up call. It highlights that our daily choices, from the food we eat to the products we use, have a profound impact on our hormonal and reproductive health. By becoming more conscious consumers and making small, informed changes, we can collectively work towards a healthier future.
