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.
This study was an in-vitro pilot study which established the effect of radiofrequency radiation from 2.4 GHz laptop antenna on human semen. A test of significance between results of semen parameters using Mann-Whitney U- test at 0.05 level of significance showed a significant effect of RFR exposure on  sperm concentration, motility and morphology grading.
The present study was performed to investigate the effect of 2.45 GHz microwave radiation (2 h/day for 35 days) on reproductive pattern of male Wistar rats. Chronic exposure to these radiations produced formation of apoptotic cells in testis. In addition, a significant decrease in the levels of antioxidant enzymes glutathione and superoxide dismutase activities as well as an increase in catalase activity was observed in the exposed group. These results indicate that a low level exposure of microwave radiations exerts a negative impact on male reproductive system function.
Reading the last paragraph of the previous section you might be saying “Ah hah! Microwaves! Microwaves are bad, they make things very hot and they could burn you!” That’s absolutely true. You would not want to build a human size microwave oven and stand inside it. Nor would you particularly enjoy being the target of the crowd-dispersing microwave cannons built and deployed by the U.S. military.

Studies by five independent research groups regarding cell phones and brain tumors have revealed significantly increased risks of a benign tumour of the cranial nerve supplying the ear. This grows slowly and must be removed in a major operation that can result in permanent facial paralysis. Other risks found were cancer of the glial cells (including neurons) of the nervous system and cancer of the meninges, the membrane covering the brain and spinal cord.
It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
