Lost in space: Sperm struggles to navigate during weightless sex

medicalxpress - Scientists have used a tiny plastic "obstacle course" to test how much sperm would struggle to navigate during sex in the weightlessness of space.

AI Summary: New research shows sperm struggle to navigate and function in weightless conditions, suggesting microgravity could impair fertilization and complicate human reproduction beyond low-Earth orbit. Scientists warn these findings raise practical and biological questions for long-duration missions and potential colonization efforts, prompting calls for more reproductive biology studies in space.
