Cell phone usage and erectile function.

Abstract

INTRODUCTION: The objective of this pilot study was to report our experience concerning the effects of cell phone usage on erectile function (EF) in men. MATERIAL AND METHODS: We recruited 20 consecutive men complaining of erectile dysfunction (ED) for at least six months (Group A), and another group of 10 healthy men with no complaints of ED (Group B). Anamnesis, basic laboratory investigations, and clinical examinations were performed. All men completed the German version of the Sexual Health Inventory for Men (SHIM) for evaluation of the International Index of Erectile Function (IIEF), as well as another questionnaire designed by our clinicians that assessed cell phone usage habits. RESULTS: There was no significant difference between both groups regarding age, weight, height, and total testosterone (Table 1). The SHIM scores of Group A were significantly lower than that of Group B, 11.2 ±5 and 24.2 ±2.3, respectively. Total time spent talking on the cell phone per week was not significantly higher in Group A over B, 17.6 ±11.1 vs. 12.5 ±7 hours. Men with ED were found to carry their 'switched on' cell phones for a significantly longer time than those without ED, 4.4 ±3.6 vs. 1.8 ±1 hours per day. CONCLUSIONS: We found a potential correlation with cell phone usage and a negative impact on EF. Further large-scale studies confirming our initial data and exploring the mechanisms involved in this phenomenon are recommended.

Main findings

In this pilot study (20 men with ED vs 10 healthy controls), total weekly time spent talking on a cell phone did not differ significantly between groups. Men with ED reported carrying a switched-on cell phone for significantly longer per day than men without ED (4.4 ± 3.6 vs 1.8 ± 1 hours/day). The authors conclude there may be a potential correlation between cell phone usage and negative impact on erectile function.

Outcomes measured

• Erectile function (SHIM/IIEF score)
• Erectile dysfunction status (ED vs no ED)

Limitations

• Pilot study with small sample size (n=30)
• Observational comparison; causality cannot be established
• Cell phone usage assessed by questionnaire/self-report
• Exposure metrics limited (no frequency/SAR or objective RF measurements reported)
• Potential confounding not described in abstract
