Space Sperm Need Gravity to Find Their Way
TL;DR
Adelaide University researchers tested human, mouse, and pig sperm in a device simulating microgravity, finding that sperm struggled to navigate a maze mimicking the female reproductive tract and showing about a 30% reduction in successful navigation under zero gravity, underscoring gravity as a key factor in early reproductive success during space conditions.
