And they also sort of play cards.

sex from behind kind of, but it's this intimate, trusting, weird situation where I think it really is saying, I'm down for you.

I'm not going to hurt you.

I'm holding your testicles and you can trust me.

I don't know, but that's interesting.

Yeah.

I mean, maybe there's an answer now and I haven't found it and someone will write in.

So I'm just going to go through the ducts a little more quickly.

There's two different systems.

So the Wolfian ducts become what I'll just say is the male internal plumbing and the Malarian ducts become what is the female internal plumbing ducts.

So what's important is that the Leydig cells produce testosterone, which stabilizes the development of the Wolffian ducts.

The testicles have to produce two hormones.

Leydig cells produce testosterone to stabilize the Wolffian ducts to connect the sperm-producing organ to the delivery system, ultimately, which is the penis.

And they have to cause...

the degeneration of the malarian ducts.

So that's anti-malarian hormone and testosterone.

So healthy testes, and this is important when we talk about the disorders or differences of sexual development, healthy testes will have those effects.

And you can also think about what happens if they can't produce anti-malarian hormone or what happens if there's no receptor for testosterone or no receptor for malarian hormone.

Not that I know of DHT for sure.

That's extremely important.
