Microsperm
“Microplastics are now 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 3 times higher than dogs.”
Yeah but what of the sperm count? Are the microplastics competing with sperm for insemination?
I bet if you could track where the little polymer bits came from, you’d find it’s from food packaging, sloughing off into it’s contents.
How they get from the stomach into your blood and then into your testicles, I’ll leave that up to the bio types to resolve. But I’m guessing that anything small enough, whether it’s plastic or otherwise will do the same. That is, it’s probably doesn’t matter and has been going on forever.
