For the first time, the US Space Agency (NASA) will send semen to space, wanting to see how the lack of gravity affects sperm’s ability to move and fertilize an egg.
The equipment for the Micro-11 experiment arrived at the International Space Station (ISS) a few days ago with Space X’s Dragon Space Shuttle. Contains frozen semen of man and bull, which will be thawed by astronauts to study it under conditions reduced gravity. Eventually, the semen will return to Earth, at the University of Kansas, where scientists will make further analyzes of how it has been affected by microbiality.
According to NASA scientists, previous experiments with bull and mouse sperm indicate that sperm are activated more rapidly in microbial conditions. But the next steps leading to penetration into the egg and its fertilization occur more slowly or not at all. These problems can ultimately prevent the fertilization of humans in space.
According to NASA researchers, the bull’s sperm cells appear more resistant and reliable in activity and morphology than human beings.
