Scientists from Yamanashi University in Japan succeeded in producing “space offspring” from mouse sperm that were taken to the International Space Station (ISS) in 2013 and brought back to Earth in 2019. It was stated that the experiment of rat sperm carried into space by freezing and drying showed that sperm can be stored in space for more than 200 years.
Japanese scientists, cosmic rays and space studied the reproductive potential of freeze-dried sperm long stored aboard the ISS to assess the biological effect of irradiation. In the experiment conducted as part of this review, scientists managed to produce mouse pups from sperm stored in space for about 5 years. Scientists have announced that they have obtained genetically normal mouse offspring without the sperm DNA or fertility being affected by space radiation. It was stated that the results of the experiment showed that sperm can be stored in space for more than 200 years.
TRANSPORTED TO SPACE BY THE METHOD DEVELOPED DURING THE SECOND WORLD WAR
Emphasizing that one of the aims of the scientific study is to evaluate whether it is possible to reproduce in space or on other planets after long space travels, scientists stated that living animals or cells are not suitable for this experiment. Sperm were brought into space in 2013 by freeze-drying, developed by the US Department of Defense during World War II to transport blood plasma and penicillin over long distances without harming them, and brought back to Earth in 2019. “Space pups did not show any differences compared to ground control pups, and their next generation did not show any abnormalities,” the article published as a result of the experiment used.
