Association between electronic device usage and sperm quality parameters in healthy men screened as potential sperm donors

Abstract

Overview

The increasing use of cell phones and exposure to radio-frequency electromagnetic radiation (RF-EMF) is a growing concern, particularly regarding its potential effects on semen quality. This study assesses the impact of electronic device usage on sperm quality among healthy men aged 22-45.

Methods

• Information on electronic devices use was collected through standardized questionnaires from 1,454 men.
• Semen analysis (volume, concentration, total count, motility) was conducted by trained clinical technicians.
• Data were analyzed using linear mixed-effect models, adjusting for multiple confounders.

Findings

Significant inverse associations were observed:

• Total duration of electronic device use negatively impacted sperm progressive motility and total motility.
• Cell phone and computer usage durations were correlated with reduced sperm concentration and motility.
• Per hour increase in cell phone use for talking decreased sperm concentration and total count substantially.
• Using headsets during calls exacerbated the negative impacts on sperm motility.

Conclusion

Electronic device usage is associated with a modest reduction in semen quality, particularly with longer daily calling times and when using headsets during calls. While no immediate reproductive hazards are confirmed for men with good fertility, precautionary measures are recommended for those planning pregnancies. Further studies are essential to explore these associations more precisely and evaluate potential clinical implications for the broader population.
