Effects of electromagnetic radiation from a cellular phone on human sperm motility: an in vitro study.

Published in: Arch Med Res 2006; 37 (7): 840-843

Aim of study (acc. to author)

To investigate possible effects on human sperm parameters exposed to electromagnetic irradiation of a GSM mobile phone in vitro.
Background/further details: The study population was composed of 27 healthy men with normal sperm parameters defined by the WHO. The sperm sample from each participant was divided into electromagnetic irradiation-exposed and not-exposed group.

Endpoint

Exposure

Exposure Parameters
Exposure 1: 900 MHz
Modulation type: pulsed
Exposure duration: continuous for 5 min
Exposure 1
Main characteristics
Frequency 900 MHz
Type
Exposure duration continuous for 5 min
Modulation
Modulation type pulsed
Exposure setup
Exposure source
Distance between exposed object and exposure source 10 cm
Chamber In the exposure room, there were no other metal or ferromagnetic materials around the clean benches made of marble that would change the structure of the EMF. The use of any EMF emitting device was not allowed.
Parameters
Measurand Value Type Method Mass Remarks
power 2 W peak value - - -
power density 0.02 mW/cm² mean - - -
magnetic flux density 7.1 µT - measured - 1.7-7.1 µT
Additional parameter details
The EMF level produced by the mobile phone stayed approximately constant during ringing and speaking. Environmental EMF levels in the analysis and the exposure room, measured on the clean benches and on the stages of microscopes, were 0.1-0.4 µT, also with the mobile phone in stand-by.
Measurement and calculation details
All EMF measurements were performed using a Triaxial Magnetic Meter.

Main outcome of study (acc. to author)

Statistically significant differences in sperm motility were observed in the rapid progressive, slow progressive and no motility categories. Electromagnetic irradiation exposure caused a subtle decrease in the rapid progressive and slow progressive sperm motility. It also caused an increase in the no motility category of sperm motility.
There was no statistically significant difference in the sperm concentration between the exposed and not-exposed group.
