Correlation between testicular volume and conventional sperm parameters or serum hormone levels (n = 78).
| Parameter | r | P value |
|---|---|---|
| Conventional sperm parameters | ||
| Seminal fluid volume (mL) | r = 0.47 | <0.05 |
| Seminal fluid pH | r = −0.11 | NS |
| Sperm concentration (million/mL) | r = −0.42 | <0.05 |
| Spermatozoa with progressive motility (%) | r = 0.43 | <0.05 |
| Spermatozoa with normal morphology (%) | r = 0.82 | <0.05 |
| Immature germ cells (%) | r = −0.64 | <0.05 |
| Serum hormone concentrations | ||
| Serum LH (mUI mL−1) | r = −0.31 | NS |
| Serum FSH (mUI mL−1) | r = −0.37 | NS |
