Sperm get lost in space, Australian research into microgravity impacts suggests Study into how fertilisation could work in space finds sperm may get disorientated when trying to find an egg Sperm in space are likely to get disoriented and lost while struggling to find their way to an egg, a new study has found. When exposed to microgravity in experiments, sperm tumble around like an untethered astronaut, according to Adelaide University researchers. “It causes them to flip around, to go upside down … they don’t really know which way is up or down,” researcher Dr Nicole McPherson said. Australia is part of Nasa’s planned Artemis mission to go to the moon and on to Mars, while private companies including Elon Musk’s SpaceX plan to build human habitats on Mars. As a result there has been increasing interest in how humans might reproduce and breed animals in extraterrestrial habitats. The Adelaide researchers used a machine to mimic microgravity – the same sort of freefall or weightlessness astronauts on the International Space Station experience. The clinostat “causes cells to not really understand or know which direction they’re going in”, McPherson said. “With the recent advancements in space travel and international interest in deep space exploration, Mars settlement and moon mining, it is critical to investigate the effect of microgravity on early fertilisation events not only for creating viable food sources, but also maintaining human space settlements, without the need to continually re-populate from Earth,” they noted in an article published in the journal Communications Biology . McPherson said the microgravity research also benefits earthly reproductive science. The researchers, from the university’s Robinson Research Institute, used sperm samples from humans, mice and pigs. They put them in a 3D clinostat machine, which spins around to negate the effect of gravity, then in a maze that was a simulation of the female reproductive tract – although in the case o...
