Abstract

Effects of 5.8 GHz Microwaves on Testicular Structure and Function in Rats Xue Y, Guo L, Lin J, Lai P, Rui G, Liu L, Huang R, Jing Y, Wang F, Ding G. Effects of 5.8 GHz Microwaves on Testicular Structure and Function in Rats. Biomed Res Int. 2022 Jun 6;2022:5182172. doi: 10.1155/2022/5182172. Abstract Objective: To investigate the effects of exposure to 5.8 GHz microwaves on testicular structure and function of male adult rats. Methods: After 30 days of exposure, we evaluated sperm quality by determining sperm concentration and quantifying the number of abnormal sperm. Testicular morphology was investigated by hematoxylin-eosin (HE) staining. The levels of testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH), glial cell line-derived neurotrophic factor (GDNF), stem cell factor (SCF), and transferrin (TRF) were determined by enzyme-linked immunosorbent assays (ELISAs). We also used western blotting to determine the levels of GDNF and SCF and apoptosis-related protein (caspase-3) in the testis. Results: Compared with the sham group, there were no significant differences in terms of sperm count, sperm abnormality, and the levels of T, FSH, LH, GDNF, SCF, and caspase-3 in the microwave group. Conclusion: Under the experimental conditions, 5.8 GHz microwave exposure has no obvious effect on testicular structure and function of rats. Open access paper: ncbi.nlm.nih.gov
