This study aimed to assess the potential harmful effects of radiofrequency-electromagnetic radiation on sperm parameters. There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, however total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage and progressive motile sperm count also decreased with wireless Internet usage compared with the wired Internet connection usage.
Whether you call them cell phones, smart phones or mobile devices, it seems like everyone has one. According to the wireless telecommunications industry, the U.S. now has an estimated 300 million mobile subscribers, compared to 110 million subscribers a decade ago. The increase in cell phone use has generated concern about possible health risks related to radiofrequency electromagnetic fields from this technology, and a market for shields as possible protection against the radio waves the phones emit. The Federal Trade Commission (FTC), the nation's consumer protection agency, has some practical tips to help you avoid scams and limit your exposure to electromagnetic emissions from your cell phone.
In recent years there has been a tremendous increase in use of Wi-Fi devices along with mobile phones, globally. Wi-Fi devices make use of 2.4 GHz frequency. The present study evaluated the impact of 2.45 GHz radiation exposure for 4h/day for 45 days on behavioral and oxidative stress parameters in female Sprague Dawley rats. Behavioral tests of anxiety, learning and memory were started from day 38. Oxidative stress parameters were estimated in brain homogenates after sacrificing the rats on day 45. In morris water maze, elevated plus maze and light dark box test, the 2.45 GHz radiation exposed rats elicited memory decline and anxiety behavior. Exposure decreased activities of super oxide dismutase, catalase and reduced glutathione levels whereas increased levels of brain lipid peroxidation was encountered in the radiation exposed rats, showing compromised anti-oxidant defense. Expression of caspase 3 gene in brain samples were quantified which unraveled notable increase in the apoptotic marker caspase 3 in 2.45 GHz radiation exposed group as compared to sham exposed group. No significant changes were observed in histopathological examinations and brain levels of TNF-α. Analysis of dendritic arborization of neurons showcased reduction in number of dendritic branching and intersections which corresponds to alteration in dendritic structure of neurons, affecting neuronal signaling. The study clearly indicates that exposure of rats to microwave radiation of 2.45GHz leads to detrimental changes in brain leading to lowering of learning and memory and expression of anxiety behavior in rats along with fall in brain antioxidant enzyme systems.
The key factor when selecting a cell phone case is making sure that you choose the exact one your phone needs. Cases are specific to not only brands of cell phone, but specific models as well. For example, if you have version three of a cell phone model, it may not fit a version six, and vice versa. Make sure that you know exactly what case you need. The cases protect the corners and back of the phone, and a clear tempered glass or Plexiglas shield protects the face. This glass or film is usually scratch- and smudge-resistant, and the cases are rubber or polycarbonate. Some cases have clips on the back that allow you to connect the phone to a belt or bag. Many cases are black, but multiple colors and patterns are available too.
A few years ago, the science regarding links between cell phone radiation and various health ailments was a very emergent science. Even today, most scientists disagree about many of the findings. However, the fact that so many new studies are discovering effects that cell phone radiation can have on human biology, it makes sense to play it safe. If there are no negative health effects, then you're only out a few bucks. But if it turns out there really are serious health issues related to cell phone radiation, then by protecting yourself early, you can protect your health and potentially save your life by getting a cell phone anti-radiation shield.

Foster was Moulder’s coauthor on that 2013 review of Wi-Fi’s health effects. He says that, based on our current understanding of radio wave strengths and risks, world health authorities have set safety standards for all devices and appliances that emit electromagnetic radiation—from phones and microwaves to your car’s keyless entry fob. “The exposure you get from your Wi-Fi router is orders and orders of magnitude below those safety limits,” he explains.
If cell phones were causing cancer we could expect a significant rise in the rate of brain and other related cancers. According to the National Cancer Institute, there was no increase in the incidence of brain or other nervous system cancers between the years 1987 and 2005 despite the fact that cell phone use dramatically increased during those same years.  Between 2004 and 2010 there was still no significant change in the incidence rate of brain tumors. Between 2004 and 2010 there was a slight increase from 209 cases to 221.8 cases per 100,000 people, but this slight increase was attributed to better tracking and recording of cases.  During the same time period, cell phone use increased 62.7% from 182,140,362 subscribers in 2004 to 296,285,629 in 2010.

Retrieved 2008-01-22. “Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which anxiety and speculation are spreading. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.”
Outside critics soon came to suspect that Carlo would be the front man for an industry whitewash. They cited his dispute with Henry Lai, a professor of biochemistry at the University of Washington, over a study that Lai had conducted examining whether cell-phone radiation could damage DNA. In 1999, Carlo and the WTR’s general counsel sent a letter to the university’s president urging that Lai be fired for his alleged violation of research protocols. Lai accused the WTR of tampering with his experiment’s results. Both Carlo and Lai deny the other’s accusations.5
W. Kim Johnson, a retired physicist and past president of the New Mexico Academy of Science, reviewed the Aires web site for Discovery News and described the material as gibberish, saying that the authors "of the technical description of the ‘Aires' device reads like a random selection of technical terminology. The working description for this device is made up of jargon that, in the end, really says nothing."
