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.
These results may be biased by two factors that reduced the sample size for CASA analysis: a) 10 of 47 (31%) samples obtained in winter 1993 could not be analyzed by CASA because of technical problems; and b) samples with fewer than 25 motile sperm tracks were not included in the analyses because we did not consider means based on [is less than] 25 sperm to be representative of the sample.
Using a computer to capture the data, several hundred sperm tracks from an individual tom can be analyzed.
