A number of studies have reported that male reproductive organs are susceptible to electromagnetic fields (EMFs). The aim of this study was to explore the effects of microwave radiation exposures on 6-8 weeks old male Swiss albino mice. Mice were divided into two groups: group I - sham-exposed (Control), and group II - microwaves-exposed (MWs). Mice were exposed to 2.45 GHz with power density 0.25 mW/cm2 and specific absorbtion rate (SAR) 0.09 W/kg. Exposure was given in Plexiglas cages for 2 h/day for 30 days. Results showed that 2.45 GHz microwave radiation resulted in a significant increase (p < 0.001) in catalase (CAT), malondialdehyde (MDA), reactive oxygen species (ROS) and decrease (p < 0.001) in the levels of glutathione peroxidase (GPx), testosterone and superoxide dismutase (SOD) (p < 0.05). Flow cytometer analysis of blood showed the formation of micronuclei in microwave-exposed group. Histopathological changes were also seen in seminiferous tubules of microwave-exposed group as compared to the sham-exposed group. It is concluded that 2.45 GHz microwave radiation exposure causes oxidative stress in testes and it may lead to detrimental and injurious effects on fertility potential of the male reproductive system of Swiss albino mice.
多项研究报告称,男性生殖器官易受电磁场(EMF)影响。本研究的目的是探讨微波辐射暴露对6 - 8周龄雄性瑞士白化小鼠的影响。小鼠被分为两组:第一组为假暴露组(对照组),第二组为微波暴露组(MWs)。小鼠暴露于2.45 GHz,功率密度为0.25 mW/cm²,比吸收率(SAR)为0.09 W/kg。在有机玻璃笼中进行暴露,每天2小时,持续30天。结果显示,2.45 GHz微波辐射导致过氧化氢酶(CAT)、丙二醛(MDA)、活性氧(ROS)显著增加(p < 0.001),谷胱甘肽过氧化物酶(GPx)、睾酮和超氧化物歧化酶(SOD)水平显著降低(p < 0.001)(p < 0.05)。血液流式细胞仪分析显示微波暴露组有微核形成。与假暴露组相比,微波暴露组的生精小管也出现了组织病理学变化。结论是,2.45 GHz微波辐射暴露会导致睾丸氧化应激,并可能对瑞士白化小鼠雄性生殖系统的生育潜力产生有害和损伤作用。
