#2476 - Shanna H. Swan

Key Takeaways

• •

  Global sperm counts are declining by 1% annually - this trend, driven by endocrine disruptors, suggests a potential fertility crisis where the majority of the population may require assisted reproduction by 2045.

  “Since 1973, sperm counts have dropped by 50% to 60%, and the rate of decline is actually increasing.”

• •

  Phthalates and PFAS are feminizing males in utero - exposure to these 'everywhere chemicals' during the critical first trimester window disrupts testosterone production, leading to permanent reproductive health changes.

  “Phthalates are particularly concerning because they lower testosterone, which is essential for proper male development in the womb.”

• •

  Personal detoxification requires systemic lifestyle changes - reducing plastic use, switching to glass containers, and eating organic are necessary steps to lower the body's chemical burden and protect reproductive health.

  “We are living in a chemical soup, and if we don't change how these substances are regulated and used, we are looking at a species-level threat.”
