The purpose of this study is to bridge this gap by investigating effects of long term 900 MHz mobile phone exposure on reproductive organs of male rats. The study was carried out on 14 adult Wistar Albino rats by dividing them randomly into two groups (n: 7) as sham group and exposure group. Rats were exposed to 900 MHz radiofrequency (RF) radiation emitted from a GSM signal generator. Point, 1 g and 10 g specific absorption rate (SAR) levels of testis and prostate were found as 0.0623 W/kg, 0.0445 W/kg and 0.0373 W/kg, respectively. The rats in the exposure group were subject to RF radiation 3 h per day (7 d a week) for one year. For the sham group, the same procedure was applied, except the generator was turned off. At the end of the study, epididymal sperm concentration, progressive sperm motility, abnormal sperm rate, all-genital organs weights and testis histopathology were evaluated. Any differences were not observed in sperm motility and concentration (p > 0.05). However, the morphologically normal spermatozoa rates were found higher in the exposure group (p < 0.05). Although histological examination showed similarity in the seminiferous tubules diameters in both groups, tunica albuginea thickness and the Johnsen testicular biopsy score were found lower in the exposure group (p < 0.05, p < 0.0001). In conclusion, we claim that long-term exposure of 900 MHz RF radiation alter some reproductive parameters. However, more supporting evidence and research is definitely needed on this topic.
本研究的目的是通过调查长期900兆赫手机辐射对雄性大鼠生殖器官的影响来填补这一空白。该研究以14只成年Wistar白化大鼠为对象，将它们随机分为两组（每组7只）：假手术组和辐射暴露组。大鼠暴露于GSM信号发生器发出的900兆赫射频（RF）辐射中。睾丸和前列腺的点状、1克和10克比吸收率（SAR）水平分别为0.0623瓦/千克、0.0445瓦/千克和0.0373瓦/千克。暴露组的大鼠每天接受3小时的射频辐射（每周7天），持续一年。对于假手术组，除了关闭发生器外，采用相同的程序。在研究结束时，评估附睾精子浓度、精子前向运动率、异常精子率、所有生殖器官重量和睾丸组织病理学。在精子活力和浓度方面未观察到任何差异（p>0.05）。然而，暴露组的形态正常精子率较高（p<0.05）。虽然组织学检查显示两组的生精小管直径相似，但暴露组的白膜厚度和约翰森睾丸活检评分较低（p<0.05，p<0.0001）。总之，我们认为长期暴露于900兆赫射频辐射会改变一些生殖参数。然而，在这个问题上肯定需要更多的支持证据和研究。
