Abstract

Impacts of electromagnetic radiation from cellphones and Wi-Fi on spermatogenesis [Article in Chinese] Zha XD, Wang WW, Xu S, Shang XJ. Impacts of electromagnetic radiation from cellphones and Wi-Fi on spermatogenesis [Review Article in Chinese] .Zhonghua Nan Ke Xue. 2019 May;25(5):451-455. Abstract 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. ncbi.nlm.nih.gov

Main findings

The review states that long-term exposure to radiofrequency electromagnetic radiation from cellphones and Wi-Fi damages male reproductive organs and adversely affects sperm number, morphology, motility, and oocyte-binding ability, potentially increasing infertility risk. It also states that low-intensity short-term or intermittent exposure has little adverse effect, and that antioxidants/anti-free radical agents (e.g., vitamin E, melatonin) may provide protection for some populations.
