| Abstract: | Polycyclic Aromatic Hydrocarbons (PAHs) exposure leads to disorders reported in female infertility patients. Our hypothesis is that PAHs accumulate in granulosa cells (Gc) according to body mass index (BMI) and directly affects its functions. All 16 high-priority PAHs were in human FF, Gc and blood plasma with the highest concentration in Gc (GC–MS/MS). Their highest concentration was in obese Gc, except for acenaphthene and acenaphthylene, and positively correlated with BMI. In FF, we noted only positive correlation between naphthalene and BMI, whereas in blood plasma positive correlation between naphthalene, acenaphthene, pyrene and BMI. Phenanthrene and naphthalene but not fluoranthene inhibited totally steroidogenesis (ELISA), CYP19A1 mRNA expression (real-time PCR) and increased oxidative stress index and catalase expression in Gc independently on BMI. While all studied PAHs decreased Gc proliferation (BrdU assay) and viability (Cell Count kit-8 assay). Thus, Gc PAHs concentrations are positively correlated with BMI and alter ovarian functions. • PAHs in human granulosa cells are positively correlated with Body Mass Index. • Phenanthrene and naphthalene totally reduced human granulosa cells steroidogenesis. • Phenanthrene, naphthalene but not fluoranthene increased oxidative stress. • Phenanthrene naphthalene and fluoranthene reduced cell proliferation and viability.
