Characteristics of ‘40%’ and ‘80%’ sperm populations, separated by incubated 13C substrate (mean ± standard deviation).
| 13Cu-glucose | 13Cu-fructose | 13C1-pyruvate | ||||
|---|---|---|---|---|---|---|
| 80% sperm (n = 15) | 40% sperm (n = 15) | 80% sperm (n = 15) | 40% sperm (n = 15) | 80% sperm (n = 15) | 40% sperm (n = 15) | |
| Concentration, 106/ml | ||||||
| Sperm | 48.7 ± 25.8 | 50.3 ± 28.3 | 43.4 ± 28.0 | 34.2 ± 20.5 | 39.1 ± 15.1 | 41.6 ± 24.6 |

| 0 h | 63.6 ± 15.1 | 52.8 ± 8.4 | 66.0 ± 13.7 | 59.3 ± 9.1 | 65.4 ± 13.2 | 52.9 ± 11.5 |
| Total motility, % | ||||||
| 0 h | 40.9 ± 23.1 | 28.0 ± 12.7 | 42.3 ± 21.2 | 33.4 ± 14.4 | 45.5 ± 19.5 | 27.3 ± 14.2 |
Concentration, vitality and motility were measured the start of incubations. Differences between ‘40%’ and ‘80%’ sperm populations were tested using a Kruskal–Wallis with Dunn’s multiple comparison test. No significant differences were found.
