Although data were generated for seven CASA parameters for each sperm track, some of these measures were significantly correlated with each other and therefore are not independent.
Consequently, sperm tracks were analyzed in two categories as defined by cells swimming either [less than or equal to] 100 [micro]m or > 100 [micro]m away from the surface of a freshly spawned egg or a microsphere.
Using a computer to capture the data, several hundred sperm tracks from an individual tom can be analyzed.
