The freeze-dried mouse sperm have given birth to a large brood of healthy small pups on the International Space Station (ISS), according to the scientists, whose study has already been published in Science Advances. This comes nearly six years after the mouse sperm started orbiting the planet.
According to the reports, a freeze-dried form of the sperm was stored on the International Space Station (ISS). The sperm produced 168 young pups when it was rehydrated on Earth.
Teruhiko Wakayama, Development Biologist, and Lead author said there was little difference between mice produced by space sperm and sperm of mouse living on the earth.
“All pups had a normal appearance,” he said.
In 2013, as many as three boxes of freeze-dried sperm were launched on the ISS for the long-term study.
