Male cellular telephone exposure, fecundability, and semen quality: results from two preconception cohort studies

Abstract

Overview

Study Question: To what extent is exposure to cellular telephones associated with male fertility?

Summary Answer: There was generally little association found between mobile phone placement in the front pocket and male fertility outcomes. However, for men with a Body Mass Index (BMI) less than 25 kg/m2, an inverse association was observed, indicating lower fecundability.

Known Context: Previous research indicates that cell phone use may negatively affect semen quality, although findings have been inconsistent.

Study Details

• Two prospective preconception cohort studies involving a total of 3100 men from Denmark and North America.
• Duration: 2012 to 2020
• Methods involved self-reported exposure to cellular phones in various locations on the body and follow-up concerning conception success.

Findings

While overall links between cell phone exposure and fecundability were minimal, specific associations were found based on BMI categories:

• Men with BMI < 25 kg/m2 showed reduced fecundability with front pants pocket cell phone placement.
• No significant findings for men with a higher BMI (≥25 kg/m2).

The study also explored semen qualities like volume, concentration, and motility but found few consistent links with cellular exposure.

Limitations

The study's measurements of exposure might not perfectly capture the true extent, possibly impacting the findings. Other factors such as occupation might have also influenced results.

Conclusion

While the overall impact of cellular phones on male fertility appears minimal, the risk could be more pronounced in leaner individuals. These findings highlight the need for deeper investigation into how specific lifestyle factors and individual characteristics interplay with electromagnetic field exposure from everyday devices.
