Dr. Bérénice Benayoun, PhD: Why Your Ovaries Age (And the Gut Connection)

Bérénice Benayoun, PhD, explains why ovarian aging may be one of the earliest and most important drivers of female aging, influencing the brain, immune system, metabolism, and long-term disease risk far beyond reproduction. She breaks down what we actually know so far, including DNA damage, mitochondrial dysfunction, fibrosis, hormonal signaling, and why the ovary appears to age faster than other tissues.

We also get into one of the most surprising findings in the field right now: a brand new study from her lab found that post-reproductive gut microbiota unexpectedly improved ovarian reserve and lowered inflammatory signals in young mice, raising a completely new set of questions about the gut-ovary connection and what may eventually be possible for ovarian health.

If you’re already paying attention to food, sleep, and overall health, cleaning products are another place where exposure adds up quickly. Branch Basics is a simple way to clean your home with fewer unnecessary ingredients and less clutter under the sink.
