Multivariate analysis for semen parameters in men and urinary BPA concentrations (n = 317).
| Urinary BPA concentration |
|
|---|---|
| Variable | β (95% CI) |
| Seminal volumea | −0.18 (−0.40 to 0.01) |
| Sperm concentrationa | 0.01 (−0.08 to 0.10) |
| Motile sperm (%)b | −0.38 (−1.66 to 0.90) |
| Morphologically normal sperm (%)c | 0.16 (−0.45 to 0.77) |
| Total motile countd | −0.05 (−0.17 to 0.70) |
| Total sperm counta | −0.04 (−0.14 to 0.06) |
n = 315 for seminal volume, and n = 314 for sperm concentration and total sperm and total motile count. BPA, sperm concentration, and total motile count were ln-transformed.
