🇺🇸MICROPLASTICS FOUND IN HUMAN TESTICLES Researchers found microplastics in all 23 human testicles and 47 dog testicles tested. Human testicles had 330 micrograms of plastic per gram of tissue, almost three times higher than dogs. Polyethylene and PVC were the most common plastics. High microplastic contamination correlated with lower sperm counts in dogs. Further research is needed to confirm effects on human sperm counts. Sources: DailyMail
