Abstract

BACKGROUND: The most common metal used in the body is iron and since it may produce ROS, it could potentially be a dangerous substance. OBJECTIVES: Regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide with iron oxide nanoparticles, on certain indexes of ovarian tissue in a rat experimental model. METHODS: This animal model was carried out in 5 groups of female rats, including control, iron oxide (15 mg) and iron oxide nanoparticles (5, 15 and 30 mg). The drugs were intraperitoneally injected daily for 16 days. On the seventeenth day the rats were euthanized by chloroform. Ovarian tissue was removed, and histological changes and iron accumulation were assessed by special staining and light microscopy. RESULTS: According to our findings, folliculogenesis was decreased in all groups receiving iron. The number of corpus luteum in the groups receiving different doses of nanoparticle was reduced and the number of atretic follicles was significantly increased in all groups compared to the control group. CONCLUSIONS: In conclusion, probably iron nanoparticles with impaired cellular oxidative pathways, reduces the number of follicles and corpus luteum and increase atretic follicles by producing oxygen free radicals and destructing microfilaments. This can cause a negative effect on the fertility of female rats.
