Right.

Which is odd because this is somehow being used as evidence that not fapping bumps up testosterone levels.

But to get the little boost of testosterone, you ultimately needed to wank.

So what is interesting is that other studies have shown this kind of thing too, that after you orgasm, and this is for both men and women, you do get a little bump of testosterone.

Okay.

It doesn't last very long.

It's just a little bump.

But it's something that we've seen in experiment after experiment.

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But the thing is that paper's been retracted.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.
