“…Various non-thermal effects of MP-emitted EMW on the central nervous system, including permeability of the blood-brain barrier, neuronal electrical activity, neurotransmitter balance, cognitive function and sleep, have recently been reviewed. 1,2 Sexual behavior is a continuum of separate but linked processes: libido, erection, ejaculation, orgasm, detumescence and refractory period. 3 Sexual behavior in the male is a good example of the mutual collaboration between the brain and the male genital system.…”

The accumulating effects of exposure to electromagnetic radiation emitted by a conventional mobile phone (MP) on male sexual behaviour have not yet been analyzed. Therefore, we studied these effects in 18 male rabbits that were randomly divided into phone and control groups. Six female teasers were taken successively to the male's cage and the copulatory behavior was recorded. Serum total testosterone, dopamine and cortisol were evaluated. The animals of the phone group were exposed to MPs (800 MHz) in a standby position for 8 h daily for 12 weeks. At the end of the study, the copulatory behavior and hormonal assays were re-evaluated. Mounts without ejaculation were the main mounts in the phone group and its duration and frequency increased significantly compared with the controls, whereas the reverse was observed in its mounts with ejaculation. Ejaculation frequency dropped significantly, biting/grasping against teasers increased notably and mounting latency in accumulated means from the first to the fourth teasers were noted in the phone group. The hormonal assays did not show any significant differences between the study groups. Therefore, the pulsed radiofrequency emitted by a conventional MP, which was kept on a standby position, could affect the sexual behavior in the rabbit.

“…In principle it seems possible that epileptic individuals may be especially sensitive to the effects of RF radiation, given the electrochemical instability of the neuron circuits involved in the cerebral electrical storms responsible for their seizures [9]. In previous work [13], we have in fact shown that radiation of the type used by the Global System for Mobile communications (GSM) triggers seizures in rats in which a seizure-prone state analogous to epilepsy had been induced by subconvulsive doses of picrotoxin [14].…”

“…On the contrary, it is wellestablished that the CNS in general [9], and the cerebral cortex in particular [10,11], is sensitive to radio frequency (RF) radiation. A radiation intensity too low to affect other organs or systems could therefore have significant pathological effects on the CNS [12].…”

Abstract-We describe an experimental set-up for exposure of small animals to radiofrequency standing waves that allows direct measurement of the power absorbed by the animal. Essentially, the setup consists of a metallic box containing an antenna and experimental animal immobilized in a methacrylate holder; a signal generator feeding the antenna; and a power meter. In addition, the box can also contain a video camera to record the animal's behaviour, and a receiving antenna (connected externally to a power meter and a spectrum analyser) to detect undesired (external) radiation and possible harmonics of the radiating system. The absorbed power measurement trivially allows calculation of whole-body mean SAR from the animal's weight; and assuming local SARs to be proportional to whole-body mean SAR, the latter can be used to adjust organ-specific SAR predictions obtained by simulation using a commercial FDTD program with a numerical phantom. The use of the system is illustrated by application to rats given subconvulsive doses of picrotoxin to induce a seizure-prone state analogous to epilepsy: levels of the neuronal activity marker c-Fos in the frontal and piriform cortex of picrotoxin-treated rats exposed to 900 MHz GSM radiation were twice as high as those of unexposed animals.

Highlights: 60 GHz MMW do not impact neuronal tubulin expression during PC12 differentiation. Exposure at 10 mW/cm² induces a slight increase in neurite outgrowth due to the thermal effect. The thermal effect impacts all parameters of the neurite outgrowth. AbstractTechnologies for wireless telecommunication systems using millimeter waves (MMW) will be widely deployed in the near future. Forthcoming applications in this band, especially around 60 GHz, are mainly developed for high data-rate local and body-centric telecommunications. At those frequencies, electromagnetic radiations have a very shallow penetration into biological tissues, making skin keratinocytes, and free nerve endings of the upper dermis the main targets of MMW. Only a few studies assessed the impact of MMW on neuronal cells, and none of them investigated a possible effect on neuronal differentiation.We used a neuron-like cell line (PC12), which undergoes neuronal differentiation when treated with the neuronal growth factor (NGF). PC12 cells were exposed at 60.4 GHz for 24 h, at an incident power density averaged over the cell monolayer of 10 mW/cm². Using a large scale cell-by-cell analysis based on high-content screening microscopy approach, we assessed potential effects of MMW on PC12 neurite outgrowth and cytoskeleton protein expression. No differences were found in protein expression of the neuronal marker β3-Tubulin nor in internal expression control β-Tubulin. On the other hand, our data showed a slight increase, although insignificant, in neurite outgrowth, induced by MMW exposure.However, experimental controls demonstrated that this increase was related to heating.Abbreviations: MMW (millimeter waves), HC (heat control).
