Humans and Animals Are Facing a Hidden Fertility Crisis, Scientists Warn

Scientists warn that synthetic chemicals and climate stress may be contributing to a global fertility crisis in humans and wildlife.

A review by toxicologists and biologists points to pesticides, plastics, pollutants, and PFAS as potential drivers of reproductive decline.

The evidence spans human infertility trends and sharp drops in fertility across birds, fish, reptiles, marine mammals, and other species.

The review highlights known harms from compounds like DDT and calls attention to poorly tested chemicals that can disrupt hormones and reproduction.
