In this fluid mechanics video, we explore the kinematics of chemotaxing sperm cells (sea urchin, \textit{Arbacia punctulata}) swimming in a chemoattractant gradient. We demonstrate that the complex swimming trajectories resulting in chemotactic behavior (`turn-and-run' motility) are comprised of several distinct flagellar maneuvers. These motility patterns likely play an important role optimizing chemotaxic motility and navigation, when the sperm cells are subjected external fluid flows.

Three-Dimensional Simulations of Ciliary Flow

In many physiological scenarios such as the respiratory epithelium, fluid propulsion is achieved through the coordinated beating of an array of organelles called cilia. However, how these cilia

Sex and flow: the consequences of fluid shear for sperm–egg interactions

Analytical and numerical models were used to estimate the propulsive force generated by sperm swimming (Fswim) and the shear force produced by fluid motion within the vicinity of a rotating egg (Fshear), and male gametes were modeled as prolate spheroids to explain sperm–egg interactions.
