and semen parameters were investigated. Our case-control included two groups of patients.
Total concentrations of PCBs were significantly higher in the low semen quality (n= 24) than
in the normal semen quality (n= 26) group. A significant negative correlation was found
between PCB 126 and viability in men with low semen quality, while PCBs 77 and 81 were
positively correlated with morphology, and PCB 118, mono-ortho and total DL-PCBs were …
