Multivariate analysis for men’s reproductive hormones and urinary BPA concentrations (n = 302).a
| Urinary BPA concentrations |
|
|---|---|
| Variable | β (95% CI) |
| FSH | 0.04 (−0.04 to 0.12) |
| LH | 0.05 (−0.01 to 0.12) |
| T | 0.01 (−0.04 to 0.06) |
| Inhibin B | −0.01 (−0.07 to 0.04) |
| E2 | 0.49 (−3.1 to 4.1) |
| SHBG | 0.07 (0.007 to 0.13)* |
| FAI | −0.05 (−0.09 to −0.004)* |
| FT | −0.01 (−0.06 to 0.03) |
| FAI/LH | −0.11 (−0.18 to −0.03)** |
| FT/LH | −0.07 (−0.13 to 0.001) |
| T/E2 ratio | 0.01 (−0.05 to 0.08) |
| T/LH ratio | −0.04 (−0.11 to 0.03) |
BPA, urinary creatinine concentration, and all hormones except E2 were ln-transformed.
