# Human sperm accumulation near surfaces: a simulation study

@article{Smith2009HumanSA, title={Human sperm accumulation near surfaces: a simulation study}, author={David. J. Smith and Eamonn A. Gaffney and John R. Blake and Jackson C. Kirkman-Brown}, journal={Journal of Fluid Mechanics}, year={2009}, volume={621}, pages={289 - 320} }

A hybrid boundary integral/slender body algorithm for modelling flagellar cell motility is presented. The algorithm uses the boundary element method to represent the ‘wedge-shaped’ head of the human sperm cell and a slender body theory representation of the flagellum. The head morphology is specified carefully due to its significant effect on the force and torque balance and hence movement of the free-swimming cell. The technique is used to investigate the mechanisms for the accumulation of…

Using a boundary-element method used to model the hydrodynamics of a bacterium propelled by a single helical flagellum, it is demonstrated that hydrodynamic forces may trap the bacterium in a stable, circular orbit near the boundary, leading to the empirical observable surface accumulation of bacteria.

It was shown that fluid stirring by spermatozoa is an important mechanism of transfer of dissolved ions, molecules, and gases to and from the cell surface and activated hamster sperm stir substantially more fluid than do preactivatedHamster sperm, even though their power outputs are not significantly different.
