But we know that two-tailed sperm have doubled. I mean, it might be the two-tail might not be the worst thing in the world. It's just extra rocket boosters. But what about the pinhead? What does the pinhead imply? Pinhead means there's no nucleus. It's a tail. So that's a true problem.

It's like a little tiny head and moving along. So if you give somebody credit for their two tails, what does your normal go up to from 4%? Oh, it depends. But maybe 20.

I see. So the more homogeneous the failures are, the more likely that you have a clear etiology.

This is the reason why even if you launch a hundred sperm at an egg, it's only one that can get in because the first guy that breaches sets off the calcium channel that shuts the, I mean, the Star Wars space analogies here are just phenomenal. Million years. Million years. No more breaches in the hull.

Is that something that we know the genetic underpinning of? We're getting there.

So it's coming around. Think about that for a second from an evolutionary perspective. That's a problem. That is the single least desirable genetic mutation you could acquire. Yeah, unless you're not making sperm. Yeah. But this is a dead end to the genome. Right. Right. So does that mean it is only an acquired mutation never inherited?

I mean, it can't be inherited presumably unless it's homozygous, but even still.

God, that's just incredible.

All right. So basically just rounding out the semen analysis. History, physical semen analysis. On the semen analysis, what if motility is the problem?

By the way, do you get that analysis the day he's in the clinic with you or is that something you follow up on an appointment with? Pretty much have it in my hand when I see them.
