The risk of impregnating three girls while masturbating in orbit has been cautioned to astronauts.
Self-indulgence is prohibited in zero gravity due to concerns that any floating sperm could cause female astronauts to become pregnant.
Conan O’Brien, the reigning US chat show host, made the strange revelation on his podcast Needs A Friend.
Conan questioned a NASA engineer about sending porn to the International Space Station during the recording.
The engineer, identified only as Smythe, told him: “No, none of that.”
And O’Brien went on: “Does porn work in zero gravity? It goes everywhere.”
Smythe told him: “Three female astronauts can be impregnated by the same man on the same session… it finds its way.”
