According to the British newspaper “The Times” reported that Hungarian scientists found that men who often carry and use cell phones can reduce the number of sperm by as much as 30%, resulting in reduced fertility. The study also showed that the cell phone tied to the belt or in the trouser pocket is the most dangerous. This is the first study showing that cell phone radiation can damage male fertility, details of the study will be presented Tuesday at the annual meeting of the European Society of Human Reproduction and Embryology in Berlin. The study surveyed 221 men over a 13-month period, comparing the sperm counts of men who regularly use cell phones with those of infrequent users. The study showed that men who wore their cell phones on their belts or in their pants pockets faced the greatest risk, with the number of sperm decreasing by nearly 30 percent in men who used their phones regularly, and many of the remaining sperm showing abnormal activity, further reducing fertility. Dr. Fayesh of the Department of Obstetrics and Gynecology at the University of Szeged in Hungary said in the study, “Continuous use of cell phones may adversely affect sperm production and male fertility, reducing the concentration and swimming ability of sperm.” The mechanism of damage has not yet been solved Unlike the results of previous studies, the researchers this time believe that cell phones in standby mode can also cause damage. Although the phone is not in use, it also constantly transmits signals to keep in touch with the nearest radio pole. Previous studies have assumed that these emissions are too short to cause damage. But researchers say the findings need to be further confirmed and to find out the causes and mechanisms of sperm damage from cell phones. Only 15 years after its introduction, it is difficult to prove conclusively, but the University of Nottingham, England, retired professor of physics emeritus Challies said: “There is no conclusive evidence of damage to health caused by cell phones, which have existed for about 15 years, but many serious diseases take longer to appear signs of disease, which the study can not show.” Challis will announce plans later this year to conduct the world’s largest study on the health effects of cell phones, hoping to track the lives of 250,000 people for at least 15 years.
