Mean percent fertilization plotted, error bars were omitted for clarity. Because sperm concentration varied slightly between replicates, sperm dilution was plotted for clarity. sperm dilutions, the influence of sperm contact time on fertilization decreased slightly. Sperm-egg contact time influences fertilization most between the and 2 min interval. This result suggests that sperm-egg contact time may be important at

Sperm-egg contact time influences fertilization most between the and 2 min interval. This result suggests that sperm-egg contact time may be important at even finer time intervals. Thus, in the multi-factorial experi- ment we chose intervals of 7, 15, 30. and 60 s. Egg concentration The results indicated no significant effect of egg con- centration, but a highly significant effect of sperm con-. Figure 3.
