The IM percentage was greater (P ≤ 0.01) for the T2 compared with the T1 group for all preservation periods(Table 1). There were no significant differences when com-paring the data for the T3 group and T1 and T2 groups at all periods where assessments were made except at 48 h and at the third month PC (Table 1). There was a lesser(P ≤ 0.01) sperm cell motility percentage at the 48 h, 1, 2 and 3 months PC periods as compared with the 5◦C period for the T1 group. There was also a lesser sperm motility percentage at 3 months PC for the T2 group and at 1, 2 and 3 months PC for the T3 group as compared with the other preservation periods (Table 1).
