Table 3.
Final risk scoring model using all three cutoffs to predict abnormal TMSC (defined as <9 million sperm/ejaculate) and outcomes based on composite score for 71 patients in current study with all three parameters available.
| Factor in Risk Score | Cut-off (1 point for each) | |
|---|---|---|
| FSH | > 2.9 mIU/ml | |
| Inhibin B | < 220 pg/mL | |
| TTV | < 34.4 cc | |
| Composite Score | Patients with normal TMSC (% of patients with that score) | Patients with abnormal TMSC (% of patients with that score) |
| 0 | 18 (100%) | 0 |
| 1 | 13 (68%) | 6 (32%) |
| 2 | 7 (33%) | 14 (67%) |
| 3 | 4 (31%) | 9 (69%) |
