New research raises questions about the impact of technology on reproductive health.
In a new study conducted by the University of Geneva in collaboration with the Swiss Tropical and Public Health Institute, a link was found between frequent mobile phone use and a decrease in sperm count in men. In a 13-year study of nearly 3,000 Swiss men between the ages of 18 and 22, researchers found that men who used the phone more than 20 times a day had a median sperm count of 44.5 million per milliliter. This is 21% less than for those who used the phone only once a week.
Interestingly, the effects of mobile phones on sperm quality, including its motility and shape, were not observed. The study was conducted in three stages: from 2005 to 2007, from 2008 to 2011, and from 2012 to 2018. This allowed scientists to note that the link between the frequency of mobile phone use and a decrease in sperm count has become less pronounced over time, despite the global downward trend.
One theory that explains this fact is that older mobile communication technologies, such as 2G and 3G, had higher transmission power compared to modern devices, and it was the electromagnetic fields created by these older technologies that could lead to a decrease in sperm count.
It is worth noting that data on phone usage was collected by self-filling out questionnaires, which may not be entirely reliable. An additional study is currently being conducted that will measure electromagnetic waves and phone usage patterns (messages, navigation, calls, etc.) and their effect on total sperm count.
Scientists emphasize that, although a link was found, a causal relationship has not been established, that is, it is impossible to say with certainty that an increase in mobile phone use leads to a decrease in sperm count, since other factors may also interfere.
However, experts who are not involved in the study believe that the data obtained and upcoming data are of great importance. Malcolm Sperrin of the Institute of Physics and Engineering in Medicine in the UK notes that the work of scientists can be an impetus for further research in this complex area. Alison Campbell, chief scientific officer of the UK infertility clinic network Care Fertility, advises men not to panic and change their habits until more data is available.
