Abstract EN

The present study was conducted to investigated the effect of electromagnetic radiations emitted from mobile phone devices in some physiological parameters and histopathological changes of male laboratory rats Rattusnorvigicus .

Forty eight of male rats were divided randomly into eight groups and each group of six rats .

Four groups of these were exposure to electromagnetic radiations by mobile phone at different time periods included (1month, 2month, 3month and 6month) while the other residual groups were considered as a control groups at same time periods .

After ending up time periods of exposure , every animals were dissect , the left and right epididymis isolated from male rats to determining number of sperms and percentage of sperm abnormalities respectively .

As such testis has eradication, which kept in proven solution (formalin 10%) to paving preparing tissues sections .

The results of the present study revealed a significant decrease ( P≤0.05) in body weight to all exposure groups comparing with each control groups in male rats , As well as gradual decrease observed in body weight of male rats comparing with exposure groups .

The results showed that the male rats which exposured to electromagnetic radiations had inhibition effect significantly ( P≤0.05) on the number of the sperms with significant increasing in percentage abnormalities comparing with control groups , Also gradual decrease observed in number of the sperms in exposure groups comparing between itself while the percentage of abnormalities was non significant increase by progressive time exposure to electromagnetic radiations .

Histologically microscopic examination results revealed that presence of histopathological changes in testis tissue performed in disassembly of connective tissue between seminal tubules , congestion of blood vessels , epithelial tubular necrosis in addition to incidence statuses of haemorrhage as well as observation of reduction the number of spermatogenic cells and sperm modicum
