Office Hours: Preparing Your Body for Pregnancy — Fertility, Nutrition & Hormones

What It Covers

Dr. Mark Hyman addresses rising infertility rates through a functional medicine lens, explaining how metabolic dysfunction, environmental toxins, nutrient deficiencies, and stress impact both male and female fertility. He provides specific protocols for optimizing egg and sperm quality, preparing for pregnancy, and recovering from IVF treatments through diet, lifestyle modifications, and targeted supplementation.

Key Questions Answered

• •Metabolic Health as Primary Driver: Insulin resistance and blood sugar dysregulation represent the leading cause of infertility, affecting ovulation, hormone balance, and egg quality. PCOS, the most common fertility disorder, stems primarily from dietary starch and sugar intake rather than ovarian pathology. Following a low-glycemic diet with adequate protein, healthy fats, and fiber while eliminating processed foods can restore normal ovulation within months and improve conception rates comparable to IVF success rates.
• •Environmental Toxin Reduction: Xenoestrogens from plastics, pesticides, and BPA disrupt hormonal receptors and reduce fertility in both partners. Practical steps include filtering drinking water with reverse osmosis, avoiding plastic food containers and microwaving in plastic, refusing thermal paper receipts containing BPA, choosing organic produce following EWG guidelines, and using non-toxic household cleaning and personal care products to minimize endocrine disruptor exposure during preconception period.
• •Critical Nutrient Optimization: Seventy percent of people show deficiencies in one or more nutrients at minimum RDA levels, not optimal ranges. Essential preconception nutrients include methylfolate for those with MTHFR gene variants, 80-100 grams daily protein per ideal body weight, omega-3 fatty acids, vitamin D, zinc, magnesium, and B vitamins. Testing homocysteine levels reveals functional folate status better than standard folate tests and prevents miscarriages and birth defects.
• •Male Fertility Factors: Sperm quality significantly impacts embryo health, placental formation, miscarriage risk, and long-term child health outcomes. Men require antioxidants, zinc, omega-3s, and CoQ10 supplementation while avoiding alcohol, excessive heat exposure, and environmental toxins. Stress dramatically reduces sperm count and testosterone in healthy men, demonstrating the importance of stress management, exercise, and sleep optimization for both partners during conception attempts.
• •Post-IVF Recovery Protocol: IVF medications deplete B vitamins, folate, magnesium, B12, and zinc while stressing mitochondrial function and liver detoxification pathways. Recovery requires two to three months of targeted support including CoQ10, N-acetylcysteine, alpha-lipoic acid for mitochondrial health, cruciferous vegetables for liver detoxification, adequate fiber for hormone elimination, and stress reduction practices. Sweating through sauna or exercise aids toxin elimination while anti-inflammatory foods reduce post-treatment inflammation.
