STORY AT-A-GLANCE
Mean sperm counts in men around the world have dropped by 51.6% over the past 50 years. Total sperm counts (TSC) are down by 62.3%, and the decline is accelerating
An environmental factor that might play a significant role in this trend is electromagnetic field (EMF) exposures from wireless technologies, also referred to as electromagnetic radiation (EMR) or radiofrequency EMF (RF-EMF)
Recent research found that men who used their cellphones more than 20 times a day had significantly lower sperm concentrations and total sperm counts (TSC) than those who only used them once a week or less, placing them at a 30% increased risk for having sperm concentration below the reference value for fertile men, and a 21% increased risk for having TSC below the fertile range
Previous studies have linked EMR from cellphones to an 8.1% reduction in sperm motility and a 9.1% reduction in sperm viability, as well as significantly higher rates of DNA fragmentation
Wi-Fi-equipped laptop computers have been linked to decreased sperm motility and an increase in sperm DNA fragmentation after just four hours of use
