Comparison of the ovarian appearance changes in mice of different groups under light microscopy (hematoxylin and eosin staining, original magnification, ×100). The normal ovarian histological structures were observed in control group. Hemorrhage (thin arrow) and vascular congestion (star) were found in PM_2.5 group. However, in PM_2.5 + aspirin, PM_2.5 + Vitamin C, PM_2.5 + Vitamin E, and PM_2.5 + ozone groups, the changes in hemorrhage (thin arrow) and vascular congestion (star) were decreased compared to the PM_2.5 group. PM_2.5: Fine particulate matter.
