Early pregnancy PFAS exposure negatively tied to late pregnancy cortisone levels
An inverse association exists between early pregnancy maternal serum concentrations of perfluoroalkyl substances (S-PFAS) and late pregnancy diurnal urine (dU)-cortisone, which signifies a reduced activity of the enzyme 11β-hydroxysteroid dehydrogenase (11β-HSD) isoform 2, according to the results of a recent study.
