The Influence of 2.45 GHz Wi-Fi Exposure Duration on Sperm Quality and Testicular Histopathology: An Exploration of Peroxidative Injury

‘Concerns have arisen about the impact of wireless technology on male fertility, particularly regarding the duration of 2.45 GHz Wi-Fi radiation exposure. This study examines the influence of various exposure durations on sperm parameters and testicular histopathology, focusing on malondialdehyde as an oxidative stress marker. Twenty-four Sprague Dawley rats were exposed for eight weeks, after which their sperm concentration, motility, and viability and testicular histopathology were assessed. Malondialdehyde levels were measured using an Enzyme-Linked Immunosorbent Assay. One-way ANOVAs with Tukey’s post hoc tests were conducted for the sperm concentration, motility, and viability; the seminiferous epithelium height; and malondialdehyde. The Kruskal–Wallis H test was used for the Johnsen Score and seminiferous tubule diameter. The results indicated that 4 h of exposure to 2.45 GHz radiation induced oxidative stress and adversely affected sperm parameters and the testicular ultrastructure. Gradual recovery was observed at 8 h, with further improvement at 24 h, suggesting the activation of cell repair mechanisms. This was supported by significant changes in testicular organ coefficients, indicating potential recovery. Our findings suggest that Wi-Fi exposure reduces sperm fertility potential, with the body showing limited capacity for complete recovery from the damage.’ https://www.mdpi.com/2076-3921/14/2/179?
