The Peter Attia Drive
#351 ‒ Male fertility: optimizing reproductive health, diagnosing and treating infertility, and navigating testosterone replacement therapy | Paul Turek, M.D.

But if you heat up the testicle, it's also close to the skin. So it's a radiator. So when the heat comes down the arterial blood, it has to cool. So it raises and lowers. And there was an article in the Journal of Irreproducible Results about 20 years ago. A man went to Big Sur and wore nothing. And he measured ambient temperature.

And then he marked on his leg with a marker where his scrotum hung, how low it hung. And he could tell the ambient temperature by how high or low his scrotum hung. He became a thermometer. So it does go up and down. Is that Peter or Tia Laffick? Journal of Irreproducible Results. Oh, God. Really cool. But it showed that it's very temperature sensitive.

And it goes up and down to regulate it closer to the body when you want it warmer, et cetera. You go into a cold shower or a plunge, where are your testicles? They're way up there. In my abdomen, yeah. And that's all the cremasteric muscle and it's all temperature driven. So it spends all of its time regulating its temperature to stay at 95%.

Now, saunas, baths, hot tubs, jacuzzis, steam rooms, change that. The worst one of those is anything underwater, submerging underwater, because you're one centimeter away, you're a liquid, it's a liquid, you're going to turn that temperature, maybe not the inner part of your body, but little kids going into hot tubs, right?

So I did a study, published it in the Brazilian Journal of Urology. I published 200 studies. This was the hardest one to get in. Everyone said, we know that it affects fertility, so we're not going to publish it. So I went into Brazilian Journal of Urology. It then went to the New York Times as a press release. That's how popular it was.

It's probably my most cited paper ever, and it's certainly not my best. It's very interesting. I took infertile men with low sperm counts and stopped the tubs. They were in hot baths. I used the word jacuzzi. Jacuzzi called me up and said, stop. Don't use that word. So I don't use that word. So hot baths or tubs. And I told them out and they went up 300%. Semen quality went up 300%.

Total mold count in three months or four months and 600% in six months. They have to give us some time. And that's that curve, the recovery curve. And we didn't look at fertility. We just looked at that recovery. And some men were zero and went up to close to normal.

Interesting. So it's motility that the price- Then I calculated after that, I calculated a lethal dose of tubbing. So what's the lethal dose?

Yeah. So lethal dose to me means you're zero. You do it enough, you have no sperm. And it came out to be 20 minutes of a hot bath or a tub, 20 minutes, 104 degrees, three times a week would probably make you zero.
