Scientists from Yamanashi University in Japan studied the reproductive potential of freeze-dried sperm long stored on the ISS to assess the biological effect of cosmic rays and space radiation.

In the experiment conducted as part of this review, scientists managed to produce ‘space offspring’ from mouse sperm that were taken to the International Space Station (ISS) in 2013 and brought back to Earth in 2019.
Scientists announced that they have obtained genetically normal mouse offspring without the sperm DNA or fertility being affected by space radiation. The results of the experiment showed that sperm can be stored in space for more than 200 years.

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 taken 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 were brought back to Earth in 2019.
In the article published as a result of the experiment “The space pups did not show any differences compared to the ground control pups, and their next generation did not show any abnormalities either.” expressions were used.
