Abstract

The present study was conducted to compare the effect of changing the spatial distance and time radio frequency (RF) radiation from mobile phone in standby mode on the structure and function of testicles. NMRI mice were randomly divided into three groups. The first group was the control and the second group (exposed group) was divided into four subgroups: groups A (A1 and A2) and groups B (B1 and B2), which were placed in plastic holder units at two distances of 5 cm and 20 cm from RF radiation, respectively. A1 and B1, and A2 and B2 were exposed to RF radiation for six and 10 weeks, respectively. The exposure duration was 5 days/week, 6 hours/day. The third group with two subgroups (sham1 and sham2) were kept in plastic holder units without being exposed to radiation and were evaluated after six and 10 weeks, respectively. The changes in the external diameters of seminiferous tubules and the height of germinal epithelium obviously depended more on the distance from the radiation source than on the exposure time. The decrease in the diameter of the testicles and sperm motility were found to be time-dependent. These effects had a clear but unpredictable dependence on the two variables of distance and RF radiation time.

摘要

本研究旨在比较手机待机时改变空间距离和时间射频（RF）辐射对睾丸结构和功能的影响。NMRI小鼠被随机分为三组。第一组为对照组，第二组（暴露组）分为四个亚组：A组（A1和A2）和B组（B1和B2），分别放置在塑料支架单元中，距离为5 cm和距离射频辐射 20 厘米。A1 和 B1，以及 A2 和 B2 分别暴露于射频辐射 6 周和 10 周。暴露持续时间为 5 天/周、6 小时/天。具有两个亚组（sham1 和 sham2）的第三组被保存在塑料支架单元中而不暴露于辐射，并分别在 6 周和 10 周后进行评估。生精小管外径和生发上皮高度的变化明显更多地取决于与辐射源的距离而不是暴露时间。发现睾丸直径和精子活力的减小是时间依赖性的。这些影响对距离和射频辐射时间这两个变量有明显但不可预测的依赖性。
