Abstract

Can extremely low frequency magnetic field affect human sperm parameters and male fertility? Muti ND, Salvio G, Ciarloni A, Perrone M, Tossetta G, Lazzarini R, Bracci M, Balercia G. Can extremely low frequency magnetic field affect human sperm parameters and male fertility? Tissue Cell. 2023 Feb 18;82:102045. doi: 10.1016/j.tice.2023.102045. Highlights • Exposure to ELF-MF at the frequency of 50 Hz (1 mT) for 2 h alters reproductive function of human spermatozoa. • ELF-MF decreased spermatozoa progressive motility. • Exposure to ELF-MF decreased non-progressive spermatozoa motility. • ELF-MF decreased the spermatozoa with typical morphology. • Exposure to ELF-MF did not alter sperm concentration. Abstract Exposure to extremely low frequency magnetic fields (ELF-MF) may have different effects on spermatozoa depending on the waveform, magnetic flux density, frequency of ELF-MF, and duration of exposure. In this study, we investigated the possible role of ELF-MF (50 Hz; 1 mT) exposure in altering sperm parameters. In this study we found that exposure to ELF-MF at the frequency of 50 Hz (1 mT) for two hours induces statistically significant alterations in progressive motility, morphology and reactive oxygen species (ROS) production of human spermatozoa, suggesting a role of ELF-MF in altering reproductive function of spermatozoa. Our results represent an important discovery in the field since occupational exposure to the sine waveform 1 mT 50 Hz ELF- MF used in our study is possible in workplace. Moreover, these electromagnetic fields are product by many electronic devices and household appliances. Thus, alterations of progressive motility and morphology of spermatozoa would be important consequences of human exposures to ELF-MF. pubmed.ncbi.nlm.nih.gov

Main findings

In vitro exposure to ELF-MF (50 Hz; 1 mT) for 2 hours was associated with statistically significant changes in progressive motility, morphology, and ROS production in human spermatozoa. The highlights state decreased progressive and non-progressive motility and decreased typical morphology, while sperm concentration was not altered.
