Both multivariate data analysis and bivariate correlations indicated negative relationships between hydroxylated PCB metabolites (OH-PCBs) and androstenedione or pregnenolone. These results suggest possible interactions with the steroid biosynthesis pathway. However, the statistical models were weak. Thus, no firm conclusions on the effects of OH-PCBs on the steroid levels of AN and PRE can be made.
