And in fact, the only study that I could find that suggested something a little bit fappulous, if you're not into fapping, is this small study from China that reported that after men didn't ejaculate for a week, testosterone levels went up and then went down on day eight.

But the thing is that paper's been retracted.

So it's interesting this idea persists, and I think one thing that really annoyed Justin while he was doing that sort of doom-scrolling...

on this topic is that some of the benefits that people said flowed from this apparent bump in testosterone didn't make any sense to him.

So, for example, people said that their skin looked better and their hair was thicker.

And from other research, we know that when you get a boost in testosterone, say you've just gone through male puberty.

And when there's some research to suggest that when men go on testosterone replacement therapy, for some folks, they actually start losing their hair.

And so bottom line, when he looks at the research that we have on testosterone and even tries to think of a mechanism, that's the other thing of like, how would...

not ejaculating boost testosterone levels, like what could possibly be happening in the body to bump that up, he starts shooting blanks.

So far, we've just looked at testosterone, but there's other things that could be going on during ejaculating that could explain some of the... The other stuff.

The other stuff, the other exciting stuff that people are talking about.

Oh, yeah.

Okay, great.

That might actually help their case a little more.

So the next thing I wanted to look at is whether not ejaculating could improve your mood and energy and maybe even boost your athletic performance, which is something that a lot of athletes think about.

Have you heard of this idea?

I mean, in the 1998 World Cup, the English coach forbade his players from having sex.

That's so funny.

You remember that, right?

Yeah.
