Objective: Purpose of the study was to research the effect of an electromagnetic field created by a high voltage line on the testes tissue and the serum biochemistry of Wistar albino male rats. At the same time, in the study also examined the protective effects of melatonin and ganoderma lucidum. Methods: In the study, 64 rats were divided into eight equal groups (n: 8). In experiments lasting 26 and 52 days, the following groups were used: High voltage (HV), HV + Ganoderma lucidum (GI), HV + Melatonin (MEL), and Sham-control. MEL (10 mg/kg) was administered intraperitoneally and GI (20 mg/kg) as oral lavage. Extremely low frequency electric (80.3 V/m) and magnetic fields (2.48 µT) were applied for eight hours per day. Results: The biochemical results of the study show an increase in total oxidant status (TOS) and oxidative stress index (OSI) level and a decrease in total antioxidant status (TAS) level in the 26 and 52 day high voltage groups, compared to the control group. In the high voltage groups, the nitric oxide (NO) value increased with the increase of the exposure period. Testicular mass (p>0.05), TAS, TOS, OSI and NO (p<0.05) were found at 26 days of comparison. Testicular weight, TAS, TOS, OSI (p<0.05), and NO (p>0.05) were found in 52 day comparisons. In routine histopathology data, we detected effects on both the 26 and 52 day HV groups, such as degeneration in spermatic cells and full structural deterioration and increasing hyalinisation. We also detected an step up in the ligament cell in the tubular field for the 52-day test groups. In melatonin added group, proliferating cell nuclear antigen (PCNA)-positive cells were more active. TUNEL assay analysis showed that there was no significant difference between the the 26 day experiment groups (p>0.05), but that there was a significant dissimilarity between the 52 day experiment groups (p<0.05). Conclusions: In our study, the oxidative effect of created by a high voltage results in changes in serum biochemistry of rats and a number of degenerative deterioration in the histological structure of testes. Aslo, it is shown that the oxidative effect created by a high voltage has negative effects on the creation of spermatogonia. GI partly protects against these effects, while melatonin is more effective in this regard.
