And so I actually didn't realise how many different things can affect the quality of your sperm, but I asked Brent to list them.

Semen volume, that's just how much gunk is coming out in total?

Oh, what do you think we should use instead?

Semen?

Yeah, anything else we could go for?

But semen you might leave around for a little bit.

Yeah, we don't want to add to the guilt around this.

That's right.

Okay.

So looks at DNA of the sperm, pH of the sample, motility, how well the sperm are moving.

Under the microscope, yeah, he can also look at the shape of the sperm.

And all of these things can affect the chance that a sperm is going to sneak its way into, you know, through the cervix and ultimately make a baby.

And so if you avoid jerking off for a few days or even a few weeks, what happens to all these things?

Yes.

All right, let's start with sperm count and volume.

Studies over and over again have found that less fapping on average means more sperm when you do cum.

And that's basically it.

It's like the semen is collecting in there, pipes are fuller.

One small study calculated that for every day the men held on and didn't ejaculate, their sperm volume increased by around 12%.

Yeah, now that huge bump, it doesn't last forever.
