Could Your Phone Be Making You Infertile? Find Out

Men who use their mobile phone frequently suffer 21 percent lower sperm concentration, according to a new study.

The quality of a man’s semen is determined by factors like sperm concentration, total sperm count, how well the sperm swims and the size and shape of the sperm.

Many studies have shown that semen quality has decreased over the last 50 years, with sperm count dropping from an average of 99 million sperm per millilitre to 47 million.

It is thought that this drop is due to a combination of environmental factors such as pesticides and radiation, and lifestyle habits such as diet, smoking, alcohol and stress.

Researchers wanted to investigate whether electromagnetic radiation emitted by mobile phones might affect semen quality.

The team, from the University of Geneva, collected data on 2,886 men aged 18 to 22, who provided a semen sample.

Participants also answered questions on their mobile phone use and where they placed it when not using it.

Analysis revealed there was a link between frequent mobile phone use and lower sperm concentration.

Men who used their phone more than 20 times a day had a 21 per cent decrease in sperm concentration compared to those who did not use their phone more than once a week.

This link was found to be more pronounced during the earlier years of the study, between 2005 and 2007, and gradually decreased with time up to 2018.

Researcher Martin Roosli, who worked on the study, said, “This trend corresponds to the transition from 2G to 3G, and then 3G to 4G, that has led to a reduction in the transmitting power of phones.”

The results also showed that where the men kept their phone – for example in their trouser pocket – did not affect semen quality.

Writing in the journal Fertility & Sterility the researchers explained that one in six couples have issues conceiving, with around half of instances attributable to the male partner.

“The use of mobile phones has increased substantially in recent decades” they said, “and there is a growing concern about the possible detrimental effects of radiofrequency electromagnetic fields emitted by these devices on human health and particularly on reproductive functions.

“This study suggests that higher mobile phone use is associated with lower sperm concentration and total sperm count.”

They added that the mechanism through which mobile phone use may affect the male reproductive system remain “unclear”.

First author Rita Rahban said, “Do the microwaves emitted by mobile phones have a direct or indirect effect? 

“Do they cause a significant increase in temperature in the testes? Do they affect the hormonal regulation of sperm production?

“This all remains to be discovered.”
