Happy Monday, listeners. For Science Quickly, this is Rachel Feltman here to give you your weekly news roundup.

I hope you're staying cool if it's finally summer wherever you're listening from, but if you need a little help with that, you'll definitely want to tune it again on Wednesday.

But for now, let's kick off the week by diving into some of the stories you may have missed.

Last Wednesday, scientists published a small

study with some pretty big implications. They found microplastics in four out of the five

penis tissue samples that they studied. And yeah, five is a pretty small sample size. Like I said,

this was a tiny study. But four to five, we don't love those odds even at

that scale. Plus, this comes just a few weeks after a different study detected microplastics

in human and dog testicles. They tested 23 human samples and 47 dog specimens and every

single one contained microplastics. So again, we're not loving

these thoughts. In both cases, researchers sounded the alarm on a potential link between

microplastics and various sexual health concerns. While neither study showed a causal link,

which is to say it's too soon to blame microplastics for any particular health problem.

The research on penis tissues specifically looked at men who came to the hospital for surgery

to treat erectile dysfunction. So we know that all of the study subjects were struggling with that

issue. And in the study from back in May, researchers noted that the dogs

with higher concentrations of certain microplastics had lower sperm counts. Some recent studies have
