Demographic characteristics of normozoospermic (N) and asthenozoospermic (AS) men
| Parameters | N (n = 61) | AS (n = 68) | P value |
|---|---|---|---|
| Age | 29.8 (22–46) | 30.6 (24–51) | n.s. |
| Semen volume | 3.5 ± 1.3 | 3.1 ± 0.9 | <0.01 |
| Sperm concentration (×106/ml) | 50.2 (18.1–140.2) | 38.5 (13.1–112.9) | <0.01 |
| Total number (×106/ejaculate) | 165.1 (48.9–482.1) | 115.4 (36.7–248.3) | <0.01 |
| Progressive motility (%) | 43.5 ± 8.5 | 16.6 ± 6.2 | <0.05 |
| Immotile sperm (%) | 38.5 ± 10.9 | 76.8 ± 6.8 | <0.001 |
| Total motility (%) | 61.5 ± 10.9 | 23.2 ± 6.8 | <0.001 |
| Hyperactivated motility (%) | 2.7 (0–17.8) | 0.6 (0–3.8) | <0.001 |
Semen volume, progressive motility, immotile sperm, and total motility followed a normal distribution and were expressed as mean ± SD; statistical comparisons were assessed by t test. The other parameters did not follow a normal distribution and were expressed as median (minimum–maximum); statistical comparisons were assessed by Mann-Whitney U test
