Comments "Machin (ref 8) has shown that the energy dissipated in the elastic deformation of the flagella amounts to one third of the hydrodynamic dissipation. So for a number c of sperm the total amount of work performed is (see eq.8 link )...A comparison of equations 10 & 8 ( link) indicates that the "efficiency" of the sperm movement is about 22 percent."
