Table 1. Comparison of viability and motility of frozen-thawed spermatozoa among the groups.

Group	Number	Pre-freezing		Post-thawing
		viability(%)	motility(%)	viability(%)	motility(%)
A(10 µm height)	12	88.6±3.0a	87.1±3.1a	51.3±2.8	49.5±2.8
B (50 µm height)	12	88.6±3.0a	87.1±3.1a	34.2±2.5b	33.5±2.6b
C (100 µm height)	12	88.6±3.0a	87.1±3.1a	13.2±2.0b	12.1±2.1b
D(conventional freezing)	12	88.6±3.0a	87.1±3.1a	50.9±2.2	49.1±2.5

^aindicates a statistical difference when compared with post-thawing spermatozoa from Group A to Group D (P<0.05);

^bindicates a statistical difference when compared with Group A (P<0.05).
