Polychlorinated Biphenyls (PCBs) Impact Prostatic Collagen Density and Bladder Volume in Young Adult Mice Exposed during in Utero and Lactational Development.

Ventral prostate lobe mass decreased in the 1 mg/kg PCB treatment group compared to the 0.1 and 6 mg/kg PCB treatment groups with no changes in any other prostate lobes ( Figure 1 A–C); however, when normalized to body mass, there were no significant differences in prostate lobe wet weights between treatment groups, though the same ventral prostate phenotype was trending toward significance with p = 0.07 ( Figure 1 D–F).
