Table 3.
Recovery (LSMeans ± SEM) of undamaged membrane, motile and progressively motile sperm after cryopreservation with different N-Methylacetamide concentration-thawing rate combinations.
| Sperm Variables 1 | Recovery Rates (%) | SEM | |||
|---|---|---|---|---|---|
| 6% 5 °C 100 s |
6% 38 °C 30 s |
9% 5 °C 100s |

| Membrane integrity | 56.5 A | 25.3 C | 40.7 B | 22.9 C | 2.7 |
| Motility | 59.5 A | 22.6 C | 40.6 B | 20.7 C | 3.1 |
| Progressive motility | 49.6 A | 9.1 C | 21.9 B | 5.3 C | 4.3 |
1 Membrane integrity: percentage of undamaged membrane spermatozoa; Motility: percentage motile spermatozoa; Progressive motility: spermatozoa swim forward fast in a straight line A, B, C; SEM: standard error of mean. Different superscripts show a significant difference among treatments within row at p < 0.001.
