AHR and Infertility: The PREVIENI cohort of Italian infertile women had a higher presence of detectable BPA serum levels, as well as enhanced expression of ERα, ERβ, AR and PXR in peripheral blood mononuclear cells (PBMCs) in comparison with fertile controls: significant correlations were also observed between ERα, ERβ, AR, AhR and PXR expression levels and BPA, MEHP concentrations and between AhR and PFOA [31].
