手机与Wi-Fi辐射对精子发生的影响

Impacts of electromagnetic radiation from cellphones and Wi-Fi on spermatogenesis

Wi-Fi技术的发展与普及使电磁辐射的暴露日益增加,因而人们对手机及Wi-Fi一类产生的射频电磁场(RF-EMF)可能对健康造成危害的担忧与日俱增,尤其是在当前男性精子浓度下降和不孕不育增加的背景下。电磁辐射的长期暴露不仅使得男性生殖器官遭到破坏,还可对精子的数量、形态、活力与卵细胞的结合能力造成负面影响,间接增加了不孕的风险。虽然电磁辐射具有一定危害性,但并非无法避免,其中低强度短时间或间断性的暴露对生殖器官及精子影响甚微,是防护的主要手段。同时许多抗氧化、去自由基试剂,如维生素E、褪黑素等,也可以满足特殊人群的防护需求。本文就电磁辐射对精子的影响以及相应防护方法加以阐述,并对电磁辐射防护发展方向作一综述。

With the development of Wi-Fi technology and widespread exposure to electromagnetic radiation ( EMR), people are increasingly concerned about the health hazards caused by radiofrequency electromagnetic fields as from cellphones and Wi-Fi, particularly about the current decline in sperm concentration and increase in male infertility. Long-term exposure to EMR not only damages male reproductive organs, but also affects the number, morphology, motility and oocyte-binding ability of sperm, and indirectly increases the risk of infertility. However, EMR is not unavoidable. Low-intensity short-term or intermittent exposure to EMR has little adverse effect on reproductive organs and sperm. And many antioxidant and anti-free radical agents, such as vitamin E and melatonin, can protect some special populations from EMR. This review presents an overview of the impacts of EMR from cellphones and Wi-Fi on sperm, some countermeasures, and prospects of EMR protection.
