Certain aspects of cell phone use may negatively affect sperm quality by decreasing semen volume, sperm concentration, or sperm count, thus impairing male fertility.

Plain English Summary

Summary written for general audiences

The study screened 794 young men in 2013 and followed 666 and 568 participants in 2014 and 2015, respectively. Univariate regression showed that daily talking duration on a cell phone was significantly associated with lower sperm concentration and total sperm count in 2013, and with lower semen volume and total sperm count in 2015. Internet use via cellular networks was associated with decreased sperm concentration and total sperm counts in 2013 and decreased semen volume in 2015, and these associations remained significant after multivariate adjustment for confounders.

Why This Matters

Consistent but nonsignificant negative associations between talking on a cell phone and semen parameters persisted across all three study years, and a mixed model combining three years of data showed a statistically significant negative association. The researchers concluded that certain aspects of cell phone use may negatively affect sperm quality by decreasing semen volume, sperm concentration, or sperm count, thus impairing male fertility.

Quick Questions About This Study

The study screened 794 young men in 2013 and followed 666 and 568 participants in 2014 and 2015, respectively.
The study examined daily duration of talking on a cell phone and internet use via cellular networks.
Daily talking duration was significantly associated with lower sperm concentration and total sperm count in 2013, and with lower semen volume and total sperm count in 2015. Consistent but nonsignificant negative associations persisted across three years, and a mixed model combining all three years showed a statistically significant negative association.
Multivariate analyses adjusting for potential confounders showed that significant negative associations between internet use and semen parameters remained.
The researchers concluded that certain aspects of cell phone use may negatively affect sperm quality by decreasing semen volume, sperm concentration, or sperm count, thus impairing male fertility.
