Sperm are known to exhibit two distinct types of motility. One is characterized by constant amplitude, symmetrical waveforms. The other is characterized by asymmetrical waveforms, which are correlated with an increase in calcium concentration. The goal of this work is to model the undulatory swimming of sperm swimming in a viscous, incompressible fluid using the method of regularized Stokeslets. Varying waveforms will be considered via a preferred curvature function. Results showing emergent waveforms, swimming speeds, and trajectories will be compared to experimental data.
