Xinhua News Agency, London, October 25 (Reporter Ge Qiufang) - A study by American scientists shows that prolonged use of mobile phones can damage male sperm, and the microwaves emitted by mobile phones may reduce both the quantity and quality of sperm.
According to recent reports by British media, scientists from the Cleveland Clinic Foundation in the United States tested 364 men in Mumbai, India, who were undergoing infertility investigations with their partners. The results found that men who used mobile phones the longest (more than 4 hours a day) had the least amount of sperm, with only 50 million sperm per milliliter of semen, and the quality of the sperm was poor. Some of these men even had less than 20 million sperm per milliliter. Men who did not use mobile phones had the highest sperm count, reaching 86 million per milliliter, and the healthiest sperm quality. Men who used mobile phones for less than 2 hours and between 2 to 4 hours had sperm counts of 69 million and 59 million per milliliter, respectively.
According to data provided by the World Health Organization, the normal sperm count for men ranges from 20 million to 200 million per milliliter of semen.
All men produce abnormal sperm, but among the surveyed men, those who used mobile phones the longest had only 18% normal sperm, while those who did not use mobile phones had up to 40% normal sperm.
Dr. Ashok Agarwal, the lead scientist of the study, said that for all four parameters surveyed—sperm count, motility, viability, and morphology—"the longer the mobile phone use, the more these parameters declined."
However, Agarwal believes that the experimental results do not prove that mobile phone use leads to reduced fertility. He called for further research by the scientific community, given the vast number of mobile phone users worldwide.
