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.

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.

And so I asked Justin, so if you don't ejaculate, you don't get that sense of relaxation, which some may interpret as tiredness, you would...

And so there have been studies that have actually looked at this in terms of sports performance.
