Smartphone Use at Night Damages Sperm

new study published in the journal Sleep found nightime smartphone use damages sperm. 116 men aged between 21 and 59 undergoing fertility evaluation completed questionnaires about their sleep habits and use of electronic devices and researchers found that the men who reported using their phone more in the evenings had a reduced concentration of sperm, and decreased  “motility” – the ability for sperm to swim correctly.

“The results of this study revealed a link between evening and post-bedtime exposure to light-emitting digital media screens and sperm quality. To the best of our knowledge, this is the first study to report these types of correlations between sperm quality and exposure time to SWL emitted from digital media, especially smartphones and tablets, in the evening and after bedtime.”

“Radiofrequency electromagnetic radiation emitted from mobile phones is one factor associated with these changes, the scientists said, as it raises the temperature of the sperm, interfering in its production,” according to The Telegraph article  entitled “Men who use smartphone at night are damaging their fertility.”

The study is entitled Light Emitted from Media Devices at Night is Associated with Decline in Sperm Quality. 

A 2017 analysis of over 40, 000 men in 50 countries found a 52.4% sperm decline in men from  North America, Europe, Australia and New Zealand. Environmental exposures from plastics to chemicals to cell phone and Wi-Fi radiation are likely an important reason for this decline.

Environmental Health Trust has compiled consistent evidence from experimental research, epidemiological studies and in vitro (cells) laboratory, and in vivo (animal) studies that shows that the radio frequency radiation exposure from wireless devices is associated with men’s reproductive health issues including:

  • Reduced sperm count
  • Reduced sperm motility and concentration
  • Damaged  sperm DNA
  • Altered sperm cell structure
  • Increased erectile dysfunction

Animal studies in female animals have found cell phone radiation impacts to ovaries and the female reproductive system as well. Source: Environmental Health Trust
