“…Lack of SP17 and PEBP‐1 expressions in rats exposed to 900 MHz EMF is found in this study similar to the previous study . The causes of this observation can be the death of motile sperms and/or inducing oxidative stress due to EMF exposure.…”

“…In previous studies, it is clear that SOD is the major protection enzyme and first defensive line against oxygen toxicity in human testes, and it is found in large amounts in spermatogonia in comparison to all other germ cells [48,49]. On the other hand, death of a spermatogonium by RF-EMF exposure has been previously reported [35,50]. We concluded that lack of SOD identification in all three exposed groups may be due to lack of viable spermatogonia in response to RF-EMF radiation.…”

“…Proteomic strategies combining 2DE and MS offer considerable potential for understanding the effects of environmental conditions on the cells. Several groups, including ours, have examined the changes of the tissues and cells during 900 MHz EMF radiation . In this study, adult male Sprague‐Dawley rats were exposed to 900 MHz EMF radiation.…”

The use of electromagnetic field (EMF) generating apparatuses such as cell phones is increasing, and has caused an interest in the investigations of its effects on human health. We analyzed proteome in preparations from the whole testis in adult male Sprague-Dawley rats that were exposed to 900 MHz EMF radiation for 1, 2, or 4 h/day for 30 consecutive days, simulating a range of possible human cell phone use. Subjects were sacrificed immediately after the end of the experiment and testes fractions were solubilized and separated via high-resolution 2D electrophoresis, and gel patterns were scanned, digitized, and processed. Thirteen proteins, which were found only in sham or in exposure groups, were identified by MALDI-TOF/TOF-MS. Among them, heat shock proteins, superoxide dismutase, peroxiredoxin-1, and other proteins related to misfolding of proteins and/or stress were identified. These results demonstrate significant effects of radio frequency modulated EMFs exposure on proteome, particularly in protein species in the rodent testis, and suggest that a 30-day exposure to EMF radiation induces nonthermal stress in testicular tissue. The functional implication of the identified proteins was discussed.

“…The effects of RFW on the brain and testis are the most popular research areas. Moreover, recent studies suggest that RFW emitted from cell phones impairs hormone secretion, such as LH and FSH, due to the deformation of Leydig and Sertoli cells, which may lead to altered cell proliferation and reduce the fertilising potential of men (Desai, Kesari, & Agarwal, ; Jelodar, Talebzadeh, & Lari, ; Markkanen et al, ; Roosli, Michel, Kuehni, & Spoerri, ).…”

The aim of this investigation was to evaluate changes in testosterone and some of the functional and regulatory molecules of testis such as P450scc, steroidogenic acute regulatory protein (StAR), tumour necrosis factor-α (TNF-α), interleukin-1α (IL-1α), interleukin-1β (IL-1β) and nerve growth factor (NGF) following exposure to 900 MHz radio frequency (RF). Thirty adult male Sprague Dawley rats (190 ± 20 g BW) were randomly classified in three equal groups, control (sham, without any exposure), short-time exposure (2 hr) (STE) and long-time exposure (4 hr) (LTE). The exposure was performed for 30 consecutive days. The testosterone level in both exposed groups was significantly less than control (p < .05). Level of TNF-α in both exposed groups was significantly greater than control (p < .05). IL-1α and NGF levels in LTE were significantly higher than the STE and control groups (p < .05). Level of IL-1β in LTE was significantly higher than control (p < .05). Expression of both P450scc and StAR mRNA was significantly down-regulated in both exposed groups compared to control (p < .05). Our results showed that RFW can affect testis and reproductive function through changes in factors, which are important during steroidogenesis, and also through changes in inflammatory factors, which regulate Leydig cell functions.

“…However, the BioInitiative working group, together with other researchers [8,10,[12][13][14][15][16], suggest that adverse health effects are observed at low levels of exposure 0.1 µW/cm 2 . Studies suggest that RF-EMF exposures with powers below the recommendations of the ICNIRP have effects related to changes in brain activity [17], affecting cognitive and motor performance [12,13], infertility problems in the male reproductive system [18,19], DNA damage [20,21], association to different brain tumors and intensity of RF-EMF, and having a greater effect in children and teenagers than in adults [4,6,12,[22][23][24][25]. These studies suggest that exposure to RF-EMF is an important factor to consider as a "possible carcinogen" classified in group 2B by the International Agency for Research on Cancer (IARC) [26].…”

A novel compact device with spectrum analyzer characteristics has been designed, which allows the measuring of the maximum power received in multiple narrow frequency bands of 300 kHz, recording the entire spectrum from 78 MHz to 6 GHz; the device is capable of measuring the entire communications spectrum and detecting multiple sources of electromagnetic fields using the same communications band. The proposed device permits the evaluation of the cross-talk effect that, in conventional exposimeters, generates a mistake estimation of electromagnetic fields. The device was calibrated in an anechoic chamber for far-fields and was validated against a portable spectrum analyzer in a residential area. A strong correlation between the two devices with a confidence higher than 95% was obtained; indicating that the device could be considered as an important tool for electromagnetic field studies.
