Effects of Iron Oxide Nanoparticles on Mouse Sperm Parameters and Testicular Tissue
Authors
Abstract:
Background: Iron oxide nanoparticles are commonly used for various purposes, such as biomedical, medical, and cosmetic services and research. However, there is a little information about the effects of the nanoparticles on human health. The current investigation was conducted to evaluate the adverse effects of iron oxide nanoparticles (FeNP) on the reproductive organs of mice, such as the testicular tissue and sperm cells. Methods: Twenty-eight male NMRI mice were randomly divided in four groups (N=7). The control group received only a regular diet. The experimental groups were administered FeNP in doses of 50, 150 and 300 mg/Kg intraperitoneally (IP), over four days. Epididymal sperm parameters, such as sperm number and motility were assessed by computer-assisted sperm analysis (CASA). Stereological analysis was also conducted on the histological sections. Results: The results demonstrated that FeNP (300 mg/Kg/day) caused a significant decrease in the sperm parameters, such as motility, spermatogonia, primary spermatocytes, spermatid, Sertoli, Leydig cells, total length of seminiferous tubules, and testicular interstitial tissue volumes. Conclusion: In summary, FeNP affected several reproductive tissue and cellular parameters at the administered dosage. Further research is required to examine the mechanism of action of FeNP the mice reproductive system.

effects of simultaneous exposure to formaldehyde vapor and noise on mouse testicular tissue and sperm parameters
conclusions exposure to formaldehyde vapor can destroy testicular structure and decrease percentages of sperm count and progressive motility. the present study indicated that a reduction in the percentage of progressive motile sperm may be potentiated by noise (700-5700 hz) in the simultaneous exposure to formaldehyde and noise group. thus, it can be anticipated that simultaneous exposure to fo...

BACKGROUND Formaldehyde (FA), one of the simplest organic molecules, is a flammable, pungent, irritating and colorless gas. This study aimed to investigate the effects of various concentrations of FA vapor on sperm parameters and testicular tissue. MATERIALS AND METHODS In this experimental study, we randomly assigned 36 adult male mice to one control and two experimental groups (n=12 for eac...

Introduction: Industrial and environmental pollution, excessive iron supplementation and blood transfusion are among the factors that may cause iron toxicity. Therefore, it is necessary to identify the mechanisms influencing or protecting against iron toxicity. The present study aimed to investigate the protective effects of quercetin as an antioxidant on hepatotoxicity induced by iron oxide an...

Formalin is widely used in industry and in medicine (as tissue fixative and disinfectant).It contains reactive molecules which have been known for its cytotoxic effects. To evaluate the effect of formalin exposure on the testicular tissue and sperm parameter from neonatal period through physical and sexual maturity, 28 male Wister rats were assigned into two equal test and control groups. The t...
