Researchers have found that cell phone signals can alter four essential features of fertile, grade A sperm: 1. Mobility -- How well they move; 2. Viability -- How tough they are; 3. Sperm count -- How many there are; 4. Morphology -- Proper composition. In men who use cell phones, multiple studies have shown that at least one, and sometimes all four of these categories were impaired compared with the sperm of men not using cell phones at all, and the groups that clocked more hours on the phone had correspondingly worse results. What's causing the damage? Theories vary. Many researchers suspect radio frequency (RF) energy, a form of electromagnetic (EM) energy necessary for making a call. EM waves are a common part of modern life and include technologies from radios to X-ray machines. The higher the EM energy emitted, though, the more damaging it can be. While cell phone RFs are considered low energy, young sperm cells are fragile and easily damaged, and thus may be sensitive to even low energy waves. Another possibility is that cell phone use impairs the brain's regulation of the hormones that control sperm production. http://www.asylum.com/gallery/are-cell-phones-causing-your-sperm-count-to-drop/482586/ Does this make sense or is it nonsense?
