The tiny plastic particles were found in all 23 human testes in a new study, and all 47 testes from pet dogs.

Microplastics have crossed so many boundaries it is hard to keep track.

The ‘red flag’ of our consumptive lifestyles, they have reached the limits of the Earth - from the Mariana Trench to the tip of Mount Everest. These tiny particles of decomposed plastic have seeped into clouds, and been found buried in archaeological remains believed to be ‘pristine’.

They have challenged our ideas of bodily inviolability too, infiltrating every organ. What might have been considered the ‘purest’ parts of human life - placentas, babies, breast milk - contain microplastics.

So it comes as little surprise that human testicles have them too, as the most comprehensive study yet on microplastics and the scrotum confirms.

Less is known about what microplastics are doing to our bodies. But in the case of testicles, the new research suggests they could be lowering sperm count.

    Yes, but look what it’s done for the profits of the Coca-Cola company and PepsiCo!

      Ans let’s remember our friends at McDonnell-Douglas and Raytheon, huh? Record profits, people! Unprecedented geopolitical instability market opportunities!

      So go on, get those microplastics in yer junk! Get ‘em in there! That’s right! We got maybe six years tops before this whole planet goes tits up, let’s move! Always Be Closing!

      Personally, I buy my microplastics at my local spice market. It’s more aromatic and flavorful for a quarter of the price of McCormick’s shit. But hey, if you want shitty flavorless plastic in your dishes that’s your choice.

          Microplastics are fine, but previous generations ate macroplastics, and they did just fine, so I include them in my diet as well.

    Headline: “Could it be microplastics?”

    Story: “oh definitely. 100%. I mean, c’mon. Seriously, it’s SO microplastics it’s insane.”

    Seeing the numbers of testes cited here as being an odd number makes me feel uncomfortable.

    petroleum derived microplastics are stored in the balls. Big Oil is sneaking into deez nutz

    The Guardian’s story on this has more of the important details

    The human testicles had been preserved and so their sperm count could not be measured. However, the sperm count in the dogs’ testes could be assessed and was lower in samples with higher contamination with PVC. The study demonstrates a correlation but further research is needed to prove microplastics cause sperm counts to fall.

    The testes analysed were obtained from postmortems in 2016, with the men ranging in age from 16 to 88 when they died. “The impact on the younger generation might be more concerning” now that there is more plastic than ever in the environment, Yu said.

    The study, published in the journal Toxicological Sciences, involved dissolving the tissue samples and then analysing the plastic that remained. The dogs’ testes were obtained from veterinary practices that conducted neutering operations.

    The human testicles had a plastic concentration almost three times higher than that found in the dog testes: 330 micrograms per gram of tissue compared with 123 micrograms. Polyethylene, used in plastic bags and bottles, was the most common microplastic found, followed by PVC.

      330 micrograms per gram

      That seems like… a lot. Way more than I expected or am comfortable thinking about.

        Just to clarify, 1 microgram is 0.001 milligrams, so 330 micrograms are 0.33 milligrams and 1 gram is made out of 1000 milligrams.

    I hope this is true, as it would mean fertility rates would fall. (Right?)

    and all 47 testes from pet dogs.

    A) nobody ask how they tested the dogs

    B) How many humans were tested in total? I’m pretty sure we feed garbage to dogs.

      The Guardian reported the dogs were from neutering operations and the humans from postmortem exams. Dogs get fed garbage meat meal but it’s packaged largely in paper bags, metal tins, or only the big bag is plastic. Human food is often kept in plastic at every step and often heated in plastic too.
