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

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.



Exposure Parameters
Exposure 1: 900 MHz
Modulation type: pulsed
Exposure duration: continuous for 5 min

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.
