Microplastics found in all human testicles tested, impacting fertility

Microplastics were found in all 23 human and 47 dog testicles tested, with human testicles having 3 times more plastic concentration. A study suggests a correlation between microplastics and declining sperm counts in men. Microplastics have been found in human blood, placentas, and breast milk, raising concerns about their impact on human health. Further research is needed to confirm the direct link between microplastics and reduced sperm counts.
