研究目的(著者による)

To investigate possible effects on human sperm parameters exposed to electromagnetic irradiation of a GSM mobile phone in vitro.

詳細情報

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.

研究の主なアウトカム(著者による)

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.
