Nanoplastics Threaten Human Fertility

The review flags nanoplastics — tiny plastic particles now in air, water and food — as plausible reproductive toxicants that may compromise gamete quality and fertility at the population level. While evidence is still emergent, their ubiquity plus mechanistic toxicity in animal studies makes them a credible candidate driver of falling birth rates. — If nanoplastics materially reduce fertility, regulation and public‑health responses would need to expand beyond classic pollutants to address a novel, diffuse environmental threat with demographic consequences.
