In 2017, scientists on the International Space Station (ISS) conducted an experiment called "Mouse Reproduction in Space" to study the effects of microgravity on mouse reproduction. The experiment involved sending female mice that had been inseminated with sperm into space and observing their ability to give birth. The results showed that the mice were able to give birth successfully in microgravity, and the offspring appeared healthy. This suggests that mouse sperm is capable of surviving and fertilizing eggs in space.

However, it is important to note that the experiment only involved mice, and it is not known whether human sperm would behave in the same way. There are several potential challenges that human sperm could face in space, including the effects of radiation, microgravity, and temperature fluctuations. Further research is needed to determine whether human sperm is capable of surviving and fertilizing eggs in space, and whether it would be possible for humans to conceive and give birth in space.
