Researchers from the University of Exeter in the UK have published a report in the journal International Environment, stating that men holding their phones in their pockets can reduce their chances of becoming fathers because phones can have adverse effects on male fertility.
Although many studies have previously suggested that the radio frequency electromagnetic radiation emitted by mobile phones can affect male fertility, there is still controversy surrounding this issue. Currently, the majority of adults worldwide have mobile phones, and about 14% of couples in income countries such as high school have difficulty conceiving.
The research team led by Dr. Fiona Matthews from the Department of Biological Sciences at the University of Exeter conducted a systematic evaluation of 10 studies, including 1492 samples. The evaluation analysts measured sperm quality in three different ways: motility (the ability of sperm to accurately move towards the egg), survival ability (the survival rate of sperm), and concentration (the number of sperm per unit of semen).
Researchers found that 50% to 85% of sperm in the control group were able to function normally, but when exposed to mobile phone environments, this proportion decreased by an average of 8 percentage points. Similar situations have also occurred in terms of sperm viability, and the impact of mobile phones on sperm concentration is not yet clear.
Matthews said that because mobile phones are widely used around the world, it is necessary to clearly identify the potential impacts of exposure to such environments. This study suggests that men who carry their phones in their pockets are exposed to radio frequency electromagnetic radiation, which can have a negative impact on sperm quality. In her opinion, this research result is particularly important for men on the brink of infertility, and she believes that more clinical studies are needed to determine the overall impact of mobile phones on the general population.
