Is frequent mobile phone use linked to reduced sperm quality in young men? Swiss study finds

The study's findings indicated that men who used their mobile phones more than 20 times per day experienced a lower sperm concentration and total sperm count. This association was most pronounced in the initial study period (2005-2007) but gradually lessened over time, coinciding with advancements in mobile phone technology and lower output power.

The study did not find consistent links between mobile phone use and sperm motility or morphology, and storing phones in pants pockets did not appear to impact semen quality. While these findings are suggestive, further research with improved exposure assessment is needed to establish causality.
