For Scientific American Science Quickly, I'm Kendra Peer Lewis in for Rachel Feldman.
This week we're doing something a little different.
We're bringing back some of our favorite episodes of 2025.
And today for our last episode of the year, we're serving up something rather spicy.
This show first aired in April.
Here's Rachel Feldman.
Just a heads up before we dive in.
Today's episode is about human sexuality.
We talk about sex sometimes using slang terms, but without any profanity.
I'd probably give this episode like a PG-13 rating.
So if you usually listen with kids,
maybe give this one a solo trial run just to make sure you're comfortable with the questions it might raise.
And if you just really don't like hearing people talk about sex,
then this episode probably isn't for you.
No hard feelings.
We'll see you on Friday.
Now that that's out of the way,
the human body is capable of doing some pretty incredible things,
including things we don't yet understand.
But few physical phenomena inspire as much speculation or debate as the one colloquially known as squirting.
