Table 2.
Differences of ROS production in neat semen and in spermatozoa suspension between fertile volunteers and subgroups of males from infertile couples
| groups | n | ROS (RLU × 103) in neat semen | ap | ROS (RLU × 104) in spermatozoa suspension | bp |
| FV | 34 | 0.26 (0.12; 0.55) | 3.5 (1.3; 13.0) | ||
| NS | 39 | 0.31 (0.12; 1.12) | <0.52 | 2.4 (1.0; 20.2) | <0.91 |
| SA | 52 | 1.1 (0.19; 4.1) | <0.005 | 9.3 (1.4; 118.3) | <0.055 |
| SA subgroups of SA EN | 27 | 0.24 (0.15; 1.30) | <0.27 | 3.9 (0.9; 28.2) | <0.1 |
| SA EL | 20 | 1.14 (0.36; 4.2) | <0.005 | 11.0 (2.0; 107.3) | <0.76 |
| SA EH | 5 | 32.3 (7.40; 55.8) | <10-5 | 385.0 (170.0; 625.0) | <10-5 |
Values are presented as median (25th; 75th percentile). The ap and bp values designate the differences in ROS production in subgroups of males from infertile couples versus FV in neat semen and in spermatozoa in PBS suspension, respectively. A value of p < 0.05 was considered significant by Mann-Whitney U test.
FV - fertile volunteers, NS - normozoospermic males, SA - males with semen abnormalities,
SA EN - subgroup of SA with negative Endtz test, SA EL - subgroup of SA with Endtz test <0.5 × 106/ml, SA EH - subgroup of SA with Endtz test >0.5 × 106/ml
