DENVER — Since men don’t typically carry handbags, they tend to keep mobile phones in their pants pockets. A recent study from the University of Exeter suggests this may not be a great idea.
According to the findings of a recent study facilitated at the university, that cell phone could actually have a negative effect on your sperm quality.
Dr. Fiona Mathews at the University of Exeter, which is in England, indicated that her team made the choice to investigate what role cell phones might play in male infertility especially because the trend is on the rise.
The review looked at findings from 10 studies, that included almost 1,500 samples of semen. To evaluate the men’s sperm quality, the scientists measured viability (the ratio of sperm that were alive), motility (the ability of sperm to move) and concentration (the number of sperm per unit of semen).
Compared to a control group, the percentage of sperm showing normal movement dropped by 8% among men who pocketed mobile phones. This group’s sperm’s ability to survive also decreased in about 9% of the samples.
The scientists write that the individual risk for sperm damage depends on how long a man keeps his phone in his pants and how much electromagnetic radiation the phone emits.
Previous studies had suggested several ways that the magnetic fields might be damaging sperm. In particular, past studies suggested magnetic fields could be generating DNA damage by promoting more unstable oxygen compounds. Also, because most men carry their phones in their pants pockets, the fields, which can cause up to a 2.3°C temperature increase on the skin, could be raising the temperature of the testes enough to suppress and interfere with normal sperm production.
