Mouse Sperm Survives In Space For 6 Years, Produces 168 Healthy Mice

Three boxes of 48 ampoules containing freeze-dried mouse sperms have reportedly survived in the ISS and produced healthy "pups". The sperms were brought back to earth and rehydrated producing 168 off-springs. Reportedly, they have not shown any kinds of birth defects or genetic mutations after being exposed to high levels of cosmic radiation for six years. The research was led by Japanese developmental biologist Teruhiko Wakayama and his team.
