Abstract

Category: Reproductive Biology, Environmental Health Tags: radiofrequency electromagnetic fields, RF-EMF, Wi-Fi, sperm damage, testicular abnormalities, rodent model, adaptive response DOI: 10.31661/jbpe.v0i0.2405-1759 URL: jbpe.sums.ac.ir Overview Concerns about radiofrequency electromagnetic fields (RF-EMF) and their potential adverse effects on reproductive health have grown. Recent evidence suggests low-level RF-EMF exposure may trigger adaptive responses that enhance cellular resilience to stressors. Objective This study investigated whether 2.45 GHz Wi-Fi radiation could reduce damage in the reproductive system of male rats exposed to heat stress. Material and Methods - 32 adult male Wistar rats were divided into four groups: control, RF-EMF alone, heat stress alone, and RF-EMF combined with heat stress. - RF-EMF exposure: 2 hours/day for 52 days. - Heat stress: 10 minutes/day for 52 days; combined group received both exposures. - Assessment: Testes and sperm parameters measured after 52 days. Findings - Improvement: The combined RF-EMF + heat group showed significant improvements in testis volume, tubular epithelium, interstitium, cell counts, sperm quality, and Leydig cells versus heat-only group (P<0.05). - Negative Effects: RF-EMF exposure alone also led to alterations in testicular weight, volume, and sperm parameters, confirming documented potential negative impacts on male reproductive health. - Adaptive Response: The study suggests a potential mechanism where mild RF-EMF acts to induce an adaptive response (AR), rendering tissue more resistant to subsequent stressors such as heat. Conclusion This pioneering research explores protective effects of RF-EMF against heat-induced testicular structural abnormalities in rats. Results suggest RF-EMF exposure may both harm and, through adaptive mechanisms, offer protection under certain stress conditions. This study highlights the complex links between EMF and reproductive health and underscores the urgent need for more research into underlying mechanisms as well as EMF safety. It is important to note that alterations in sperm parameters and germinal cell count are consistent with literature linking environmental EMF exposure to male fertility risks.

Main findings

In male rats exposed to heat stress, the combined RF-EMF (2.45 GHz Wi-Fi) + heat group showed significant improvements in multiple testicular histology measures and sperm quality compared with the heat-only group (P<0.05). RF-EMF exposure alone was also reported to cause alterations in testicular weight/volume and sperm parameters, indicating potential negative reproductive effects in the absence of heat stress.
