I'll mount one of these ewes, and they never do.

And I don't know how you can explain that except that there's some aversive component involved.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

that rams do care about the sex of their partner, and that for these gay rams, there's some aversive component to that.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

By the way, Chuck told me not too long ago, there's a company

Huberman Lab

that has identified these gay rams and decided that instead of sending them off to slaughter, they're going to harvest their wool and sell them and make them into clothing.

Huberman Lab

So you can buy wool clothing that came from gay rams and know that you saved them from the slaughterhouse.

Huberman Lab

And apparently they're out of stock.

Huberman Lab

So it's been a big success.

Huberman Lab

And I guess I left off the kicker, which is Chuck eventually dissected the preoptic areas of these various rams, and he found a difference between the preoptic area of gay rams and straight rams, a difference in how they process testosterone.

in exactly that part of the brain, the preoptic area, where Simon saw a difference between gay and straight men.

So there may be something about the hypothalamus, the preoptic area, that has something to do with orientation, if we're talking about an organism as complicated enough to have an orientation, including sheep.

Huberman Lab

I think the data are still out.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

But I think it's, to me at least, it's pretty clear that for men at least, there's an asymmetry here.

Huberman Lab

That experiment where I said, you know, who wants to have sex with George Clooney?

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

Half the population says, sure.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

The other half of the population, never.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

If we reverse the experiment, what percentage want to have sex with Margot Robbie?

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

And yeah, half the population, the men would see her as a very desirable sexual partner.

Huberman Lab
How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

But, you know...

Huberman Lab

The women too would โ€“ many women would also โ€“ would at least consider the idea of having sex with her.
