Published in: Reprod Toxicol 2017; 67: 42-47

Aim of study (acc. to author)

A cohort study was conducted in the USA to examine the potential association between self-reported mobile phone use patterns and semen quality in multiple samples among men.

Further details

Semen quality was assessed using four parameters (volume, concentration, sperm motility and morphology) according to the criteria of the World Health Organization.
