Space reproduction hurdles: microgravity slows sperm and embryo development

TL;DR

A University of Adelaide study used a 3D clinostat to simulate microgravity and found that sperm from humans, mice, and pigs had about 30% fewer chances to reach eggs in microgravity, while embryos formed under these conditions initially appeared stronger but degraded with longer exposure. The results suggest mammalian reproduction in space could be highly challenging for long-term space settlements, though future work could explore partial gravity (Moon/Mars) and potential IVF advances on Earth.
