Study type: Medical/biological study (experimental study)

The influence of direct mobile phone radiation on sperm quality. med./bio.

Published in: Cent European J Urol 2014; 67 (1): 65-71

Aim of study (acc. to author)

The effects of an acute in vitro exposure to a 900/1800 MHz GSM electromagnetic field on human sperms should be investigated.

Background/further details

32 healthy men with normal sperm parameters donated a sperm sample, respectively. First, each sample was incubated for 1 hour without exposure and subsequently the test parameters were measured for the first time. Subsequently, the samples were divided equally into two portions, A and B. Portions A of all participants were used as control, portions B were exposed.

Main outcome of study (acc. to author)

DNA fragmentation and non-progressive motility were significantly increased, whereas progressive motility was significantly reduced in exposed sperm samples compared to control.
The authors conclude that an acute in vitro exposure of human sperms to a 900/1800 MHz GSM electromagnetic field influences sperm motility and DNA fragmentation and that further long-term investigations are needed to evaluate possible consequences for male fertility.
