This protocol describes a method for screening high-quality sperm with a low DNA fragmentation index by utilizing sperm motility characteristics and thigmotaxis. The method employs a U-shaped horizontal swimming lane, enabling high-quality sperm to reach the opposite side through buffer droplets, while dead sperm, cell debris, and impurities are excluded.
