“…Li D.K. et al obtained different results with respect to 50 Hz, while Tateno H. et al, who investigated the occurrence of chromosomal aberrations in sperm exposed to a similar range of frequencies, did not find any differences between the control and study groups [35,36]. Formicki K. et al, while studying exposure of fish reproductive cells to the magnetic field, observed an improvement in the parameters of sperm movement, and an increased percentage of conceptions [37].…”

Electromagnetic radiation (EMR) emitting from the natural environment, as well as from the use of industrial and everyday appliances, constantly influence the human body. The effect of this type of energy on living tissues may exert various effects on their functioning, although the mechanisms conditioning this phenomenon have not been fully explained. It may be expected that the interactions between electromagnetic radiation and the living organism would depend on the amount and parameters of the transmitted energy and type of tissue exposed. Electromagnetic waves exert an influence on human reproduction by affecting the male and female reproductive systems, the developing embryo, and subsequently, the foetus. Knowledge concerning this problem is still being expanded; however, all the conditionings of human reproduction still remain unknown. The study presents the current state of knowledge concerning the problem, based on the latest scientific reports.

Previous studies on the clastogenic effects of mutagens on human sperm chromosomes were reviewed.A marked increase of structural chromosome aberrations has been reported in the spermatozoa irradiated in vitro with five kinds of ionizing radiation ( 137 Cs gamma-, 60 Co gamma-, X-, and 3 H beta-rays and 252 Cf neutrons). The micronucleus test with hybrid 2-cell embryos generated from human sperm and hamster oocytes was shown to be useful as a simple and rapid method for assessing the effects of radiation. Radiosensitivity of human spermatozoa was highest, being followed by golden hamster, Chinese hamster and mouse spermatozoa.Chromosome-damaging effects were also found with some chemicals (bleomycin, daunomycin, methyl methanesulfonate, triethylenemelamine, neocarzinostatin, N-methyl-N'-nitro-N-nitorosoguanidine, and mitomycin C), but not with other chemicals (urethane, nitrobenzene, dioxin, cyclophosphamide, benzo(a)pyrene, and N-nitrosodimethylamine). The clastogenicity of chemical metabolites was confirmed for cyclophosphamide and benzo(a)pyrene, by using the S9-based metabolic activation system. The results of sperm chromosome analysis from cancer patients who had undergone radio-and/or chemotherapy were contradictory among investigators and further studies are necessary. The importance of mutagenicity testing with human spermatozoa is discussed.

“…Despite this, the majority of studies conducted to date have found no consistent evidence of magnetic field induced effects on genotoxicity using an array of field intensities: 0.001-1 mT (Paile et al, 1995;Luceri et al, 2005;Stronati et al, 2004;Testa et al, 2004;Luukkonen et al, 2011;Saha et al, 2014), and 5-400 mT (Antonopoulos et al, 1995;Tateno et al, 1998;Miyakoshi et al, 2000). Yet there have also been several studies, both in vivo and in vitro where positive correlations have been reported; for example a significant three-fold elevation in SCE was observed in mouse m5S cells exposed to 400 mT (50 Hz) for 40 hours (Yaguchi et al, 1999).…”
