(DAILY MAIL) — Human sperm has been sent to the International Space Station (ISS) for the first time, as Nasa tries to find out if humans could ever conceive in space.

Carried aboard Elon Musk’s SpaceX Falcon 9 rocket, the sperm will be the subject of a number of experiments to see how space and low gravity affect male sex cells.

Astronauts onboard the ISS will thaw the frozen sperm to see if sex in space would lead to successful reproduction.
