Fertility in men: A recent Swiss study, considered the largest of its kind, points to a possible negative connection between cell phone use and sperm quality. According to Martin Röösli, co-author of the study and researcher at Swiss TPH, there is evidence that more intensive use of cell phones - be it for making calls, writing messages or surfing the Internet - is associated with poorer sperm quality. The results suggest that men who use their cell phones more often may have lower sperm concentrations.
In detail:
Mobile phones have become an integral part of our lives. But what effects does constant use have on our health, especially on male fertility? Swiss researchers have carried out a study on this.
Decrease in sperm concentration – what’s behind it?
It has been found that sperm concentration in men worldwide has decreased by more than 50%. While Israeli scientists came to similar results last year, the causes remained largely unclear. Factors such as environmental pollution - including endocrine disruptors, pesticides and radiation - as well as behaviors such as diet, alcohol consumption, smoking and stress could contribute.
Swiss study on cell phones and male fertility
The University of Geneva and the Swiss Tropical and Public Health Institute conducted a study with 2,886 men aged 18 to 22. The researchers examined the connection between cell phone use and sperm quality. Participants were asked about their cell phone habits, health and lifestyle.
Findings and insights
Surprisingly, researchers found that men who used their cell phones more than 20 times per day had an average sperm concentration of 44.5 million per milliliter. In comparison, men who used their cell phones less than once a week had an average concentration of 56.5 million sperm per milliliter. That's an impressive difference of 21 percent.
Possible explanations and future directions
Although the exact reasons for these results are not yet clear, researchers have a few theories. It is known that high temperatures can affect sperm production, but researchers do not believe heat is the main factor. They speculate that cell phone radiation could have an influence on the hormonal system. However, it has also been found that smartphones operating on 4G networks appear to have less negative impact on sperm quality than those operating on 2G or 3G networks.
Recommendations and conclusions
Although the study does not provide any specific recommendations for action, the researchers recommend using cell phones less, especially if the reception quality is poor. It might also make sense to pay attention to the radiation level (SAR) when buying a new cell phone. However, the researchers point out that further research is needed to understand the exact relationships and underlying factors.
Conclusion:
The increasing reliance on cell phones could have unexpected effects on health, particularly male fertility. It's important to stay informed and make conscious decisions about our technology habits.
