Astronauts have been warned not to masturbate in space because it poses the risk of impregnating three females.
Self-pleasuring is banned in zero gravity amid fears any floating semen could leave female astronauts pregnant
The bizarre revelation was made on US chat show king Conan O’Brien’s Needs A Friend podcast.
During recording, Conan asked a Nasa engineer if he had ever sent porn to the International Space Station.
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.”
