But for some folks, they have a lot of DNA damage in their sperm, which you can check by doing a test.

He's like, have sex.

But he also said that by the time people are seeing him in the clinic, it's so stressful.

And he is saying to someone, you just have sex, whatever, can also be very stressful.

All right, our last question for the day, I asked Justin.

So then are there any risks to semen retention?

I guess if you are not in the baby-making world, is it bad if you feel good about not ejaculating?

Yes, because online you do see some quite hysteric headlines about the dangers of not ejaculating.

And the one thing that people do point to, there's sort of one bit of science evidence for this, is around prostate cancer.

Have you heard this?

There is some research suggesting that folks who ejaculate a lot have a lower risk of prostate cancer than those who ejaculate a little.

But we're not really sure what's going on here.

Prostate's big job is to help make semen.

And so possibly by clearing out the pipes, you are clearing out potentially harmful things that could build up in there.
