Prepubertal uterine wet weight was approximately 16% greater in females housed in the used polycarbonate caging with used polycarbonate water bottles relative to mice housed in used polypropylene cages, although the results were not statistically significant (p = 0.31).
Our findings here suggest that aquatic laboratory animals may be exposed to BPA due to leaching from worn polycarbonate caging in sufficient amounts to significantly affect reproductive parameters.
