Effects of 2100 MHz radio frequency radiation on ductus epididymis tissue in rats

PURPOSE: The use of mobile phones is widespread since the beginning of 1990s. A great debate exists about the possible damage that the Radio Frequency-RF radiation from mobile phones exerts on different organs. The objective of this study was to investigate the possible histopathological effects of 2100 MHz RF radiation on rat ductus epididymis tissue using a light microscopy and immunohistochemical method after one or two month exposure. MATERIALS AND METHODS: The study was performed on 36 adult Wistar albino rats. 2100 MHz RF radiation was used with a specific absorption rate (SAR) of 0.36 W/kg for 30 min/day, 6 days per week for one or two months. There were 3 groups (n=6 for each group): one month RF exposed group, two months RF exposed group, and the control group. RESULTS: At the end of the study, the structural changes in ductus epididymis tissue were evaluated. In both 2100 MHz RF exposed groups, the rat ductus epididymis sperm were not observed in some channels, a reduction in sperm density in some of the channels drew an attention. The loss of connective tissue and edematous areas were observed in cross channel interstitial connective tissue. In addition, it was observed that vascularization was highly increased with respect to the control group in cross-channel interstitial connective tissue. CONCLUSION: 2100 MHz RF exposure resulted in some structural changes in the male genital ducts of rats (Tab. 1, Fig. 5, Ref 20). Text in PDF www.elis.sk.
