Age, reproductive hormones, and testicular volume differences between groups, which were grouped according to testicular histological results, with Mann–Whitney U-test
| Sperm group (n=196) | Azoospermia group (n=207) | P | |

| Age (year) | 28.00 (26.00, 32.00) | 28.00 (26.00, 31.00) | 0.199 |
| INHB (pg ml−1) | 111.86 (84.83, 152.66) | 14.30 (11.00, 37.34) | <0.001 |
| FSH (IU l−1) | 5.06 (3.53, 6.85) | 16.34 (11.91, 21.57) | <0.001 |
| LH (IU l−1) | 4.83 (3.29, 6.59) | 8.52 (6.00, 11.30) | <0.001 |

Data were shown as median (upper quartile, lower quartile). INHB: inhibin B; FSH: follicle-stimulating hormone; LH: luteinizing hormone; T: testosterone
