How do Sperm Swim? —

<p>The tail (flagellum) of the sperm does not simply push the body, but uses a rhythmical beating with pushing and fraying over a 4-beat pattern, as demonstrated in the video.</p> <p>The new dynamical model for a swimming sperm was developed by Kenta Ishimoto at Kyoto University using high-frame-rate microscopic images to obtain detailed information of the moving tail.</p> <p>The hope is that by understanding the swimming mechanism used by sperm, we may be able to better treat infertility issues in the future.</p> <p>Research by Kenta Ishimoto at the University of Kyoto.</p>
