569: Why Fertility Is Declining – Inflammation, Toxins and What You Can Do | Natalie Crawford, MD

Declining global fertility rates and rising sperm count drops signal a growing mismatch between modern lifestyle and human biology. Board-certified reproductive endocrinologist Natalie Crawford identifies chronic inflammation, metabolic dysfunction, and environmental toxins as primary drivers of reproductive struggles. Endocrine-disrupting chemicals found in plastics, non-stick cookware, and tap water mimic hormones, creating "static interference" in the body's communication system. Metabolic health is equally critical, as insulin resistance affects 27% of women with recurrent pregnancy loss and alters ovarian function in those with PCOS. Crawford emphasizes that fertility serves as a "red flag" for overall cellular health, noting that sperm quality can be meaningfully improved within a three-month lifecycle through behavioral changes. Prioritizing seven to eight hours of sleep, engaging in resistance training to build skeletal muscle, and eliminating cannabis use are actionable strategies to enhance fecundability. Proactive testing, such as AMH blood work and semen analysis, provides essential data for informed family planning before infertility occurs.
