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.
