Table 3. Background information on the study population with a comparison of semen parameters between the normal and abnormal groups.
| Semen parameter | Normal group (n=199) | Abnormal group (n=1893) | p-value |
|---|---|---|---|
| ORP (mV/106 sperm/mL) | 0.88±1.64 | 5.08±14.24 | 0.001 |
| Sperm total (×106) | 231.01±171.96 | 108.30±147.38 | 0.001 |
| Progressive motility (%) | 48.08±10.87 | 15.81±15.29 | 0.001 |
| Total motility (%) | 57.19±10.44 | 41.26±17.16 | 0.001 |
| Normal morphology (%) | 6.76±3.49 | 4.87±7.46 | 0.001 |
| Sperm concentration (×106/mL) | 70.53±50.82 | 34.72±31.16 | 0.001 |
| Volume (mL) | 3.47±1.41 | 3.18±2.29 | 0.001 |
Values are presented as mean±standard deviation or range. Sperm parameters and ORP values in patients with at least one abnormal semen parameter versus normal semen parameters.
ORP: oxidation-reduction potential.
