FIG. 6.

Motility analysis of Fyn-null and WT sperm is shown. CASA motility analysis was performed with cauda epididymal sperm from five different Fyn-null and WT males following incubation under noncapacitating conditions lacking NaHCO₃ and BSA (A) or capacitating conditions (B), as described in Materials and Methods. Motility values represent the mean percentage ± SD of sperm within each classification category (1700 spermatozoa ± SD per sample were analyzed). In order to determine whether values for WT and Fyn-null sperm were significantly different, means were compared using a t-test (n = 5). Asterisk indicates significantly different values (P < 0.05).
