Microplastics and endocrine-disrupting chemicals in everyday products—from coffee makers to yoga pants—are silently shrinking sperm counts, lowering testosterone, and driving a fertility crisis that affects humans and animals alike. Environmental epidemiologist Shanna H. Swan reveals how a simple lifestyle detox can reverse these effects in as little as three months, and why the government won't protect you. Couples in a three-month intervention who eliminated plastic exposure through lifestyle changes saw measurable improvements in sperm quality and fertility without medical intervention, with some participants achieving pregnancy after years of trying.
