Possible adverse effects of extremely low frequency magnetic fields (ELF-MF) are linked to a decrease of antioxidant defenses and the production of free radicals. The increase of free radicals affects the mitochondrial functionality inducing apoptosis, which affects the phosphorylation and generation of key ATP in fertilization. Myrciaria dubia, known as "camu camu," is a fruit with high levels of ascorbic acid, which exerts an important antioxidant function in the prevention of premature cell damage. In this study, the effect of Myrciaria dubia flour on oxidative damage produced by ELF-MF (610 μT) was evaluated by detecting the activity of endogenous mitochondrial oxidoreductase enzymes in a complete sperm cycle of mice. We found that the MF caused a significant (P < 0.05) decrease in sperm quality, whereas the groups supplied with Myrciaria dubia flour (50 and 75 mg/kg of body mass) in ELF-MF exposure showed a significant recovery (P < 0.05) in parameters of viability, percentage of plasma membrane integrity and mitochondrial activity, and index of epidymal sperm. This suggests that Myrciaria dubia flour would have an antioxidant activity that counteracts the damaging effects of ELF-MF in spermatogenesis and could be used as a natural ELF-MF protector.

桃金娘（Myrciaria dubia）“ camu camu”粉作为雄性小鼠不育症中的磁保护剂。

极低频磁场（ELF-MF）可能产生的不利影响与抗氧化剂防御能力的降低和自由基的产生有关。自由基的增加影响线粒体功能性诱导凋亡，从而影响受精过程中关键ATP的磷酸化和生成。杜仲Myrciaria dubia，被称为“ camu camu”，是一种具有高水平抗坏血酸的水果，它在预防过早的细胞损伤中起着重要的抗氧化作用。在这项研究中，通过检测小鼠完整精子周期中内源性线粒体氧化还原酶的活性，评估了杜仲粉对ELF-MF（610μT）产生的氧化损伤的作用。我们发现MF导致精子质量显着下降（P <0.05），而在暴露于ELF-MF的条件下，提供了杜仲粉（50和75 mg / kg体重）的组在生存力，质膜完整性和线粒体活性百分比以及血脂指数方面显示出显着的恢复（P <0.05）。附睾精子 这表明桃金娘科面粉具有抗氧化活性，抵消了ELF-MF对精子发生的破坏作用，可以用作天然的ELF-MF保护剂。生物电磁学。40：91-103，2019.©2019生物电磁学会。这表明桃金娘科面粉具有抗氧化活性，抵消了ELF-MF对精子发生的破坏作用，可以用作天然的ELF-MF保护剂。生物电磁学。40：91-103，2019.©2019生物电磁学会。这表明桃金娘科面粉具有抗氧化活性，抵消了ELF-MF对精子发生的破坏作用，可以用作天然的ELF-MF保护剂。生物电磁学。40：91-103，2019.©2019生物电磁学会。
