Objective To explore the effects of electromagnetic radiation of cellular telephone on sperm damage in mice.Methods Mice were exposed to electromagnetic fields with frequency of 935 MHz and power density of(0 μW)/cm~2,(570 μW/cm~2),(1 400 μW/cm~2) for 35 days(2 h/day).By the end of five weeks the mice were sacrificed,the testis and epididymis were severed and weighed.And the count,motility and morphology of sperm in epididymis were investigated.Histology of testis and ultra structure of spermatogenic cell were observed by light and electron microscope respectively.Results No significant difference of the organ coefficient of tests and epididymis between the 3 groups was found(P0.05).The sperm motility[(40.82±4.73)%]in the radiation at power density of(1 400 μW/cm~2) was significanfly reduced(P0.05),and the change ultra structure of sperm in the group appeared.Conclusions Electromagnetic radiation of cellular telephone might have sperm toxicity in mice.
