From Inflammation to Conception: Solving the Fertility Puzzle
Mark Hyman
Mar 31, 2025
Episode description
Fertility challenges are increasingly linked to lifestyle and environmental factors that go far beyond reproductive organs. Emerging science reveals that metabolic health, inflammation, diet, and exposure to environmental toxins all play a profound role in hormonal balance, egg and sperm quality, and even early embryo development. Key drivers of dysfunction—such as ultra-processed food, insulin resistance, gut imbalances, and mitochondrial damage—are rarely addressed in conventional fertility care, despite their deep impact. Paying attention to these overlooked root causes offers not only a powerful path to improving fertility but also the foundation for lifelong health in both parents and their future children.
In this episode, I discuss, along with Kelly LeVeque, what we can do to improve our fertility, which ultimately impacts the future health of our children.

Fertility in Crisis: Exploring the Toxic Threats to Fertility and the Rise in Infertility
Mindsip insights from this episode:
Recognize male fertility decline in early to mid-30s
Male fertility drops by about 52% in the early to mid-30s, a timeline that is surprisingly similar to the drop experienced by women.
Manage body fat to balance testosterone and estrogen levels
An enzyme in fat tissue called aromatase converts a man's testosterone into estrogen, leading to higher body fat, low sex drive, and reduced fertility.
Balance sugar intake to regulate insulin and hormone levels
A diet high in sugar and starch leads to high insulin, which increases testosterone in women (causing PCOS) but leads to low testosterone in men.
Boost male fertility with antioxidants for higher pregnancy success
Men taking antioxidants have a four times higher rate of getting their partner pregnant and a five times higher rate of that woman having a live birth.
Explore prenatal supplements for men to enhance sperm health
Companies like 'We Natal' are creating prenatal supplements specifically for men to protect sperm quality, morphology, and DNA.
Walk over 4,000 steps daily to boost testosterone levels
Men who walk over 4,000 steps a day have higher testosterone, and each additional 1,000 steps can increase it by another 7 ng/dL.
Balance gut bacteria to prevent estrogen dominance
Certain bad gut bacteria produce an enzyme that unpacks estrogen your body is trying to excrete, causing it to be reabsorbed and leading to estrogen dominance.
Quickly eliminate endocrine-disrupting chemicals for rapid results
If you remove sources of endocrine-disrupting chemicals, you can see their excretion in your urine decrease by half within just a few days or a week.
Maintain vitamin D levels above 40 ng/mL to reduce infertility risk
Published data shows an increased risk of infertility if your vitamin D level is below 40 ng/mL, a deficiency that may affect 80% of the population.
Address nutrient depletion from birth control pills for fertility
Birth control pills can deplete key nutrients needed for pregnancy, including folate, B-vitamins, vitamins C and E, magnesium, selenium, and zinc.
