Summary

Story summary

Kyoto University researchers examined mouse spermatogonial stem cells sent to the International Space Station for six months.
The returned cells remained healthy, supporting normal gene expression in offspring, indicating potential for human reproduction in space.
Research on human reproduction in space is limited; further studies are necessary to assess microgravity and radiation impacts on female reproductive health.
