The ratio of rapid sperm with a motility rate (%) of 25 µm s−1 or more was significantly lower at µG (□) than at 1G (▪) during parabolic flight. The percentage of static sperm was significantly increased (chi‐square test). The measurement temperature was at 30°C in the motility analyzer. Rapid, >25; medium, ≥10 ≤25; slow, <10; static, 0 (µm s−1).
