Conclusion (acc. to author)

Men with mobile phone storage in trouser pockets compared with non-users showed a higher percentage of pathologic sperm morphology and reduced luteinizing hormone level. No combined effect of varicocele and mobile phone storage in trouser pocket was observed.

Limitations (acc. to author)

Data on amount of time of mobile phone use and storage in the trouser pockets were not available, thus exposure assessment is very imprecise.
