Effects of long-term exposure to radiofrequency radiations emitted by mobile Jammers on reproduction parameters in rats

摘要

Objective:To evaluate the effect of long-term exposure to radiofrequency radiations emitted from mobile jammers onrat''s reproductive parameters.Methods: Eighty male rats were divided into neonatal group (n=20), immature group (n=30) and mature group (n=30). Neonatal rats were randomly divided into two subgroups. Immature and mature rats were randomly divided into three subgroups. Experimental rats were fixed in the restraining tube and were exposed to radiofrequency radiations emitted from mobile jammers at a distance of 100 cm, for 30 d (7 h/d). Sham group rats were also fixed in restraining tube but without radiations. The control group was allowed to move freely without being exposed to radiation. At the end of the experiment, weight of testes, sperm quality, histological testicular sections and serum testosterone levels were evaluated.Results: Long-term exposure to radiofrequency from mobile jammers could adversely affect neonatal rat fertility, but it did not have significant effects on male mature and immature rat''s reproduction parameters. However, restraint stress induced by immobilizing them for a long-period could adversely affect male mature rat''s reproductive parameters, but it had no significant effect on male immature rat''s reproduction parameters.Conclusion:The effects of EMF exposure to be various based on the life stage.
