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.



Exposure Parameters
Exposure 1: 900–1,800 MHz
Modulation type: pulsed
Exposure duration: intermittent every 10 minutes for 5 hours (standby mode with outgoing calls every 10 minutes)

Exposure 1

Main characteristics
Frequency 900–1,800 MHz
Exposure duration intermittent every 10 minutes for 5 hours (standby mode with outgoing calls every 10 minutes)
Modulation type pulsed
Repetition frequency 217 Hz
Exposure setup
Exposure source
Distance between exposed object and exposure source 5 cm
Chamber exposure and control samples were placed in two separate incubators (temperature at 27 °C)
Setup exposure incubator was equipped with mobile phone as exposure source; mobile phone was placed 5 cm away from the samples and was turned on
Sham exposure A sham exposure was conducted.

No parameters are specified for this exposure.

  • before exposure
  • during exposure
  • after exposure

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.
