この研究は、ウィスター雄ラットを対象に、ばく露には携帯電話機(1910.5MHz)を用いて60日間(1日2時間、週6日)、通話モードの連続ばく露を行い、ばく露終了後に摘出した精巣の重量、精子数などを評価した。それぞれ6匹のばく露群、擬似ばく露群は換気用の小孔を明けたプラスチック容器内に拘束してばく露(擬似ばく露)した。模擬シナリオとは、容器上面に配した携帯電話固定板をステップモータで動かし、携帯電話とラット頭部との角度を小刻みに変化させたばく露を指し、これを携帯電話の実際の使用状態の模擬であると述べている。その結果、ばく露群では精巣損傷パラメータが有意に影響を受けたと報告している。

The effects of a chronic whole body exposure of rats to a 1910.5 MHz electromagnetic field on the male reproductive system should be investigated.
12 male rats were equally divided into two groups: 1) sham exposure and 2) exposure. The experiment was repeated twice.
周波数 | 1,910.5 MHz |
---|---|

ばく露時間 | continuous for 2 hours/day on 6 days/week for 60 days |

チャンバの詳細 | one animal per Plexiglas cage (length: 55 cm, width: 17.5 cm, height: 15 cm), ventilated with holes of 2 mm diameter |
ばく露装置の詳細 | a mobile phone was placed on top of each exposure chamber; the phone was kept on "talk mode" at a fixed frequency and was connected to a stepper, which was programmed to keep the phone on an angular movement from 2° to 20° (moving at 2°/min) above the cage during exposure to simulate actual movement of a mobile phone during use |
Sham exposure | A sham exposure was conducted. |
The sperm concentration, testicular weight and the diameter of seminiferous tubules were significantly reduced in exposed animals compared to sham exposure while the concentration of malondialdehyde was significantly increased, indicating increased oxidative stress. Moreover, the comet assay revealed significant differences in exposed samples compared to sham exposure, indicating an increase of DNA strand breaks.
The authors conclude that a chronic whole body exposure of rats to a 1910.5 MHz electromagnetic field can affect the male reproductive system.
