TRANSCRIPT:

Space Exploration and Reproduction

JOE ROGAN: So, Jamie, what was your question?

JAMIE: It was to Lex, but it was really like, you see, I wouldn’t know. Hardcore science question. Yeah. Based on physics.

JOE ROGAN: Okay.

JAMIE: In theory, if you were in space and you maybe ejaculated, is it possible that the ejaculate would propel you backwards? Like send you, you know, like is it propulsion? Is there enough power in there to propel you?

LEX FRIDMAN: There’s only one way to find out.

JOE ROGAN: It depends on how long you hold it in for. Right? Like if you didn’t jerk off for like four months, and then you have like the mother load.

JAMIE: I mean, you need something to go one way, so you go the other way. Yeah, yeah. And Lex had an answer, but I don’t know. What?

JAMIE: He had a thought, I guess. What if you blow out at the same time? Yeah, yeah. Yeah.

LEX FRIDMAN: I think in space, like the biodynamics of the liquids is different. Oh, yeah. I think it’s actually difficult to have sex in space and to get people pregnant in space.

JOE ROGAN: Has anybody ever gotten pregnant on the space station? Are they allowed even to have sex?

LEX FRIDMAN: No, nobody has officially had sex in space. Officially. Officially, but unofficially, of course, people have tried.

JOE ROGAN: I wonder if they have. I mean, how monitored are they?

LEX FRIDMAN: There is a Wikipedia page about sex in space, and it’s actually pretty detailed.
