TOKYO: Male mice that spent more than a month in space were able to successfully reproduce back on Earth, a study has found, the first evidence of how space travel affects reproduction in mammals.
Some of the mice experienced the weightlessness of microgravity, while others were in cages designed to offer artificial gravity. The team, led by Masahito Ikawa, a professor at Osaka University, also examined the reproductive organs of the space-travelling mice, and checked their offspring for any signs that their parentage had negative effects."We conclude that short-term stays in outer space do not cause overt defects in the physiological function of male reproductive organs, sperm function, and offspring viability," says the study published Tuesday in the journal Scientific Reports.
