2.3 Table 3
Table 3 showed sperm motility under various durations. It was discovered that the motility of the test group
became less than 50% after 48 hrs while the control group became less than 50% after 96 hrs.
P(0.00) < 0.05. This is statistically significant. However, Pearson correlation analysis shows strong positive
relationship (0.9) between the two groups.

2.4 Table 4
In Table 4 it was observed that the percentage % live for the test group became less than 50% after 48 hrs and
were all dead by 120 hrs while the control group was less than 50% after 96 hrs.
P(0.00) < 0.05. This is statistically significant. However, Pearson correlation analysis shows strong positive
relationship (0.9) between the two groups.

2.5 Table 5
In Table 5 the sperm mass activity was observed to drop to ++ after 24 hrs and was 0 after 120 hrs while the
control group was ++ after 48 hrs but was still + at 168 hrs.
P(0.02) < 0.05. This is statistically significant. Pearson correlation analysis shows strong positive relationship (0.9)
between the two groups.
