Microplastics Found in All Tested Male Testicles

Microplastics have been found in all tested male testicles. Scientists tested the testicles of men and pet dogs and found microplastics in all samples studied. This could explain the long-observed decrease in sperm count. The concentration of plastic in human testicles is nearly three times higher than in dog testicles. Polyethylene, used in plastic bags and bottles, was the most common contaminant.
