Semen parameters and sDF in the recruited subjects for DGC, SW-G and SW-P selection.
| Variable | DGC (n = 20) | SW-G (n = 20) | SW-P (n = 20) |
|---|---|---|---|
| Total sDF before selection (%) | 41.5 ± 24.9 | 41.5 ± 19.5 | 41.5 ± 12.1 |
| Total sDF after selection (%) | 47.4 ± 33.4 | 27.0 ± 23.4 | 31.4 ± 21.0 |
| P-valuea | 0.522 | 0.001 | 0.080 |
| Viable sDF before selection (%) | 26.1 ± 24.5 | 24.8 ± 20.4 | 20.5 ± 13.0 |
| Viable sDF after selection (%) | 39.8 ± 33.9 | 23.6 ± 22.0 | 21.7 ± 21.4 |
| P-valuea | 0.167 | 0.707 | p = 0.825 |
Data are mean ± SD. aBefore versus after selection; t-Test, paired data. DGC, Density Gradient Centrifugation. SW-G, swim up conducted with good quality semen samples. SW-P, swim up conducted with poor quality semen samples. sDF, sperm DNA fragmentation
