Mouse sperm, freeze-dried and stored aboard the ISS for nine months has survived, proving it's ability to stand the harsh environment in space.
Japanese scientists announced this week that despite exposure to cosmic radiation 100 times higher than control samples left on earth, mouse sperm is capable of forming viable embryos that can grow into healthy pups.
The research study published in the journal Proceedings of the National Academy of Sciences of the United States of America, is a sign that human reproduction in space might be viable.
When those pups grew up they themselves were healthy and they were fertile, they can have their own babies.— Chris Smith, The Naked Scientist
They did check the integrity of the DNA they found that there was a small amount of damage sustained by the sperm DNA in space and that is because it is being impacted by a hundred times more radiation in space than it would at the earth's surface.— Chris Smith, The Naked Scientist
