Figure 3From: Stimulation of human damaged sperm motility with hydrogen molecule Effect of H 2 treatment on human sperm velocity. Ten sperm suspensions were treated with H2- or N2-mixed gases for 30 min, and time-lapse movies of sperm motility were recorded with a microscope for 10 s. No significant difference was observed between control and treated groups. Data are represented as means ± standard deviation (SD).Back to article page
