Lost in Space: Microgravity Makes Sperm Lose Their Sense of Direction
Simulated microgravity reduced fertilization rates by about 30% after 4–6 hours, highlighting challenges for human reproduction in space and the role of gravity in sperm navigation.

As the U.S. and China are increasingly concerned about the objective of establishing a long-term presence on Monday and March, the question of the possibility of reproduction in space could not be just a hypothetical one. And new research carried out under conditions simulated by microgravitation identified several major challenges, ...
Microgravity also profoundly disrupts sperm, egg, and embryo development, which is not good news for humanity's long-term space travel plans.

ecotopical.comLost in space: Microgravity makes sperm lose their sense of direction
Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize an egg. In lab experiments simulating space conditions, far fewer sperm successfully made it through a maze designed to mimic the reproductive tract, and fertilization ra…
New scientific research has raised alarming questions about the possible future of humanity in space. It shows that in microgravity, human sperm lose their ability to navigate and are unable to reach an egg effectively. The discovery could have major implications for reproductive options during long-duration space missions and plans to colonize other planets.
