The future is full of prospects for human beings. Our scientists are toiling to find a habitable planet other than Earth since we have caused irreversible damage to the planet. Soon, the human settlement will move to space and colonize new planets. Progressing on the same, scientists have found that procreation in space might be a possibility for us.
In 2013, freeze-dried mouse sperm was sent to the International Space Station for 9 months. The batch was brought back in May 2014 to fertilize in vitro and transferred into female mice. To everyone’s surprise, healthy mice were born who grew up to be normal.
Scientists observed that the birth rate and sex ratio were similar to the earth preserved sperms. Even though the space radiation on International Space Station was 100 times stronger than that of Earth, only a little damage to DNA was recorded. The damage got repaired in embryos following fertilization.
The sperm was kept at room temperature in space, unlike earth where freezers are used. This paves a path for freezer-free sperm preservation in the future. The experiment has found a great preservation method for human sperm.
Now that procreation is possible in space, hope for space colonization strengthens. It is not just a significant finding in advanced sperm preservation, but also our ticket to space.
