To investigate the effect of exposure to a 900 megahertz (MHz) electromagnetic field (EMF) on the rat testicle.
Twenty-four adult male rats were divided into control, sham and EMF groups. The EMF group rats were exposed to 900 MHz EMF (1 h/30 day), and testicles were extracted at the end of the experiment. Malondialdehyde, superoxide dismutase, catalase and glutathione levels and apoptotic index and histopathological damage scores were compared.
Histopathologically, EMF group rats exhibited vacuoles in seminiferous tubules basal membrane and edema in the intertubular space. Seminiferous tubule diameters and germinal epithelium thickness were both smaller, and apoptotic index was higher, in the EMF group than in the other groups. Malondialdehyde, superoxide dismutase, catalase and glutathione values in the EMF group decreased significantly compared to those of the control group.
The results show that exposure to 900 MHz EMF causes alterations in adult rat testicular morphology and biochemistry.
研究暴露于900兆赫（MHz）电磁场（EMF）对大鼠睾丸的影响。
将24只成年雄性大鼠分为对照组、假手术组和电磁场组。电磁场组大鼠暴露于900 MHz电磁场（1小时/30天），实验结束时取出睾丸。比较丙二醛、超氧化物歧化酶、过氧化氢酶和谷胱甘肽水平以及凋亡指数和组织病理学损伤评分。
组织病理学上，电磁场组大鼠的生精小管基底膜出现空泡，管周间隙出现水肿。与其他组相比，电磁场组的生精小管直径和生精上皮厚度均较小，凋亡指数较高。与对照组相比，电磁场组的丙二醛、超氧化物歧化酶、过氧化氢酶和谷胱甘肽值显著降低。
结果表明，暴露于900 MHz电磁场会导致成年大鼠睾丸形态和生物化学发生改变。
