Abstrakt:	Objective: Phenanthrene, a polycyclic aromatic hydrocarbon, is found in abundance in environmental pollutants, food, and drinking water. This substance can accumulate in body tissues and exert harmful effects. Moreover, phenanthrene can cross the placental barrier, potentially impacting fetal development. We aimed to explore the impacts of maternal exposure to phenanthrene on testicular tissue and Sertoli cell function in F1 mice. Methods: Female rats with vaginal plugs were randomly assigned to one of three groups: control, sham, or phenanthrene. The control group received no intervention during pregnancy. In the sham and phenanthrene groups, corn oil and a phenanthrene solution, respectively, were administered via gavage once every 2 days. Offspring were separated by sex 21 days after birth. At 56 days postnatal, male F1 offspring were euthanized, and their testes were harvested for histological and molecular analyses. Results: Phenanthrene exposure was associated with a lower testicular weight and volume, a smaller diameter of the seminiferous tubules, and a relative thinning of the germinal epithelium. These changes were associated with increased cellular apoptosis, as shown by the upregulation of caspase 3 expression. Additionally, we observed an increase in vacuolization and residual bodies within the tissue. Conversely, the number of Sertoli cells and expression levels of Sox9, as well as the Ocln and Itgb1 genes, were found to be lowered. Conclusion: Maternal exposure to phenanthrene impacts both germ cells and Sertoli cells, disrupting their function and leading to fertility disorders in male F1 offspring mice.
