ABSTRACT

High-power microwaves (HPMs) have been reported to have hazardous effects on multiple human and animal organs. However, the biological effects of 1.5-GHz HPMs on the reproductive system are not clear. Here, we studied the effects of 1.5 -GHz HPM whole-body exposure on the pathological structure of the testicles and changes in spermatozoa mobility. C57BL/6 mice of groups L, M, and H were exposed to 1.5-GHz HPM fields for two 15-min intervals at the average specific absorption rates of 3, 6, and 12 W/Kg, respectively. The pathological structure of the testicles and spermatozoa, as well as serum testosterone and sperm motility parameters, were evaluated at 6 h, 1 d, 3 d, and 7 d after exposure. As a result, there were no significant pathological or ultrastructural changes in the testicles or spermatozoa and serum testosterone levels. The number of progressively motile spermatozoa, curvilinear velocity, linear velocity, and average path velocity of the exposure group increased at 6 h, decreased at 1 d, and recovered at 3 d. The opposite results were considered a stress response to the thermal effect of the microwaves. Our results indicated that 1.5-GHz HPM whole-body exposure in mice at SARs of 3, 6, and 12 W/Kg for 30 min did not cause obvious damage to the reproductive system.

1.5GHz 高功率微波照射对雄性小鼠生殖系统的影响

摘要

据报道,高功率微波 (HPM) 对人体和动物的多个器官都有危险影响。然而,1.5-GHz HPMs 对生殖系统的生物学影响尚不清楚。在这里,我们研究了 1.5 GHz HPM 全身暴露对睾丸病理结构和精子流动性变化的影响。L、M 和 H 组的 C57BL/6 小鼠分别以 3、6 和 12 W/Kg 的平均比吸收率暴露于 1.5 GHz HPM 场,间隔两个 15 分钟。在暴露后6 h、1 d、3 d和7 d评估睾丸和精子的病理结构,以及血清睾酮和精子活力参数。结果,睾丸或精子和血清睾酮水平没有明显的病理或超微结构变化。暴露组逐渐活动精子数、曲线速度、线速度和平均路径速度在6 h时增加,在1 d时减少,在3 d时恢复。相反的结果被认为是对微波热效应的应力响应。我们的结果表明,小鼠全身暴露于 3、6 和 12 W/Kg 的 1.5-GHz HPM 全身 30 分钟不会对生殖系统造成明显损害。
