describes alarming results from a study that tested testicle samples from 23 humans and 47 pet dogs, finding microplastics in every single subject: 330 micrograms of microplastics per gram of tissue and 123 micrograms found in the dogs.. "When I first received the results for dogs I was surprised. I was even more surprised when I received the results for humans."
Besides the jarring prevalence, the team was also concerned about the heightened concentration of polyethylene and PVC found in the human samples, which came from postmortem subjects ranging in age from 16 to 88.link between reduced sperm counts and microplastics exposure "PVC can release a lot of chemicals that interfere with spermatogenesis," Yu explained, "and it contains chemicals that cause endocrine disruption."
