ABSTRACT
The increasing users of microwave appliances such as cell phones caused an increasing interest on investigation of its adverse effects on human health and development of animals. This study is done to investigate the effects of simulating cell phone waves on gonads and sex cells of male Balb/C mouse. This is an experimental study in which with the use of generating apparatus of simulating cell phone waves, adult male mice were exposed to cell phone waves for 10 days [4 hours per day]. Then structure and ultrastructure of testes and number of sex cells were examined by light and transmission electron microscope. Data was analyzed using t and Mann Whitney testes. The results did not show any significant differences in the size and weight of testes in mice exposed to the simulating cell phone waves. Results also showed that the number of spermatogonia cells and primary spermatocytes and spermatids and sperms were significantly increased in exposed mice [p<0.05], but the number of sertoli cells were significantly decreased [p<0.05]. The study of micrographs showed changes in ultrastructure of sexual cells, such as cleft and hetrochromatined nucleus and decrease of cell organelles and vacuolization of cytoplasm. Results indicate the effect of simulating cell phone waves on number and ultrastructure of sex cell in male Balb/C mouse
