Testing human sperm chemotaxis: how to detect biased motion in population assays.
Biased motion of motile cells in a concentration gradient of a chemoattractant is frequently studied on the population level. This approach has been particularly employed in human sperm chemotactic assays, where the fraction of responsive cells is low and detection of biased motion depends on subtle...

In these assays, statistical measures such as population odds ratios of swimming directions can be employed to infer chemotactic performance.
