Abstract

Background: Substantial evidence indicates that exposure to extremely low frequency-electromagnetic fields (ELF-EMFs) affects male reproductive system.

Objective: The goal of this study was to evaluate the effects of long-term irradiation with ELF-EMF on sperm quality and quantity and testicular structure.

Material and methods: In this case-control study, sixty male Sprague-Dawley rats were randomly divided into six groups. Experimental groups were exposed to ELF-EMF (50 Hz EMF, 100 µT) for either 1 h/day for 52 days (Group 1), 4 h/day for 52 days (Group 3), 1 h/day for 5 days (Group 5), 4 h/day for 52 days (Group 7). Groups 2, 4, 6 and 8 were only sham exposed at durations equal to Groups 1, 3, 5 and 7, respectively.

Results: Both count and motility of sperms were significantly decreased in animals exposed to ELF-EMF (1 h/day for 52 days, 4 h/day for 52 day, and 4 h/day for 5 days) compared to the sham-exposed groups (P<0.05). Serum testosterone levels showed a significant decrease in the animals exposed to ELF-EMF (4 h/day for 5 days) compared to the control groups (P<0.05). A significant decrease was observed in the volume of the seminiferous tubules, seminiferous tubules epithelium and interstitial tissue in the animals exposed to ELF-EMF for 4 h/day for 5 days. Tubules length was also reduced by 18% in animals exposed to ELF-EMF (4 h/day for 5 days).

Conclusion: Our results show that ELF-EMF can reduce spermatocyte count and motility and is able to induce structural changes in testicular tissue.

极低频电磁场(ELF-EMF)会降低精母细胞数量和活力,并改变睾丸组织。
背景:大量证据表明,暴露于极低频电磁场(ELF-EMFs)会影响男性生殖系统:本研究的目的是评估长期暴露于极低频电磁场对精子质量和数量以及睾丸结构的影响:在这项病例对照研究中,60 只雄性 Sprague-Dawley 大鼠被随机分为 6 组。实验组暴露于 ELF-EMF (50 赫兹电磁场,100 µT),每天 1 小时,持续 52 天(第 1 组);每天 4 小时,持续 52 天(第 3 组);每天 1 小时,持续 5 天(第 5 组);每天 4 小时,持续 52 天(第 7 组)。第 2 组、第 4 组、第 6 组和第 8 组只进行假暴露,时间分别与第 1 组、第 3 组、第 5 组和第 7 组相同:结果:与假暴露组相比,暴露于ELF-EMF(每天1小时,共52天;每天4小时,共52天;每天4小时,共5天)下的动物精子数量和运动能力均明显下降(PPC结论:我们的结果表明,ELF-EMF对精子的运动和数量均有影响:我们的研究结果表明,ELF-EMF 能降低精母细胞数量和活力,并能诱发睾丸组织结构的变化。
