He mounts several times, and the male rat acts like nothing's going on.

I mean, it's just a bored thing on Earth, and Romeo eventually gives up.

Now I drop into the cage a male rat who I castrated on the day of birth 90 days before, and I've given him the same hormones I gave the female to make her receptive.

Romeo hops on, and sure enough, a beautiful lordosis, right?

Of the sort that the control male never showed.

So here this neonatally castrated male is showing very female-like patterns.

And Ms.

Stahl kept asking me, would you say this is a gay rat?

And it's – I'm sitting there and I'm definitely in a tough spot because I don't think my rats have an orientation.

I mean we just saw Romeo happily mount any rat he threw in the cage because what do you know?

Try your luck.

And so she asked me – I knew she wanted me to say that.

But I said what I would say – I don't remember exactly what ended up in the final –

What I would say is this is a rat whose sexual behavior has been permanently changed because of something that happened to him a long time ago.

at the very beginning of development.

And really, that's the best I can do in terms of any rat model of sexual orientation.

I don't think my rats have a sexual orientation.

If I give the female those hormones, she's going to show lordosis to whoever mounts her.

And my male rat, he will mount any rat he comes across just in case he gets a lordosis out of them.

Certainly not.
