E138. How Much Can Everyday Chemical Exposures Affect Fertility? with Dr. Carmen Messerlian
Episode 138
Tuesday, 3 November, 2026
How much can the chemicals in everyday life—in our water, food packaging, and personal care products—affect fertility? And how much of it is within our control? Dr. Carmen Messerlian is a reproductive epidemiologist and former Harvard professor who has spent her career studying how environmental exposures relate to couples' fertility and pregnancy outcomes. She is also the founder of Vie, a fertility platform for couples. We talk about body burden and why she doesn't aim for perfection, the first change she'd make at home, and why she sees the months before conception as a window of both vulnerability and opportunity for each partner. She explains how many months she suggests for preparing for conception, and that the egg that became you formed while your mother was still in your grandmother's womb. She also shares her own experience of pregnancy loss. Guests speak for themselves. Their conclusions are their own, including where they state them more firmly than the published research does.
