So it's the equivalent of the Brazilian butt procedure for the testes. Yeah.

Medicare approved? No. Creatively approved. So let's shift gears and talk about other modifiable factors. Let's talk about heat. We've talked about it a little bit. So for fertility. Yes, for fertility. So tell me about the impact of cold plunging and sauna and hot tubbing on fertility for men. Okay.

They overheat. So you get into a 105 degree hot tub, which is a very typical temperature for a hot tub is 105 to 110. You're saying within a relatively short period of time, your testes will assume that temperature. You're 70% liquid. This is right at the surface.

So fertile men. Yep. Trying to conceive. Yeah. These are men who are not able to conceive. You're making the diagnosis. I think it's your hot tub. Let's get you out of there. And they have a six-fold increase in sperm count. Total model sperm count, meaning count motility, mainly driven by motility.

Yeah, what's the LD50?

Yeah, what's the LD50?

There have to be a lot of guys out there who are spending at least three times 20 minute sessions in a hot tub that's at least 104 degrees a week.

So my friend was absolutely right to have those ice packs on his scrotum. I think he's reading. Yeah. He's a smart guy. The Turk protocol.

They work optimally. Okay. Let's talk about exercise. You mentioned one example of exercise that can be problematic, which was, I believe you said in a study where men were ramped up to two hours a day of exercise that was above 80% of VO2 max, which is pretty strenuous. That's right. That was enough to put a dent in their fertility. Tell me about riding a bicycle. I'm a biker.

Yeah, Brooks leather saddles.

Yeah, Brooks leather saddles.

But what was the control group? Did they have a control group of runners? I don't remember. I don't think so. So in other words, it could have been the exercise. It could have been the intensity of their exercise.
