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. 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. <br />  </p>
