2014年6月12日 讯 /生物谷BIOON/ --近日，刊登在国际杂志Environment International上的一篇研究论文中，来自英国埃克塞特大学的研究人员通过研究表示，长期将手机放于裤子口袋中或会负面影响男性的生育能力。
此前研究中，研究人员表示，许多设备释放出射频电磁辐射（RF-EMR）往往对男性的生育能力具有不利影响，大多数的成年男性都会有手机，而且在高收入或者中等收入国家中大约有14%的夫妇会发生不孕不育。
这项研究中研究者对10项研究，涉及1492份样本的数据进行了一项系统性地回顾分析，旨在揭示环境暴露对人类机体的潜在影响；研究中的参与者来自不孕不育诊所以及研究中心，研究者均通过三种方式来检测男性的精子质量，包括检测精子的运动性、活性以及浓度。对照组中50%-80%的精子都会进行正常的运动，研究者表似乎，当暴露于手机辐射下时仅有8%的精子会进行正常运动，类似的效应也在精子的活力中表现了出来，而且手机辐射对精子的浓度影响表现尤为明显。
研究者Mathews教授说道，目前世界范围内手机已经被人们广泛使用了，因此环境因子暴露的潜在影响需要分清，这项研究强有力地揭示了射频电磁辐射对男性不育能力的影响，后期还需要更为深入的研究来揭示手机辐射对一般人群的影响。（生物谷Bioon.com）

Effect of mobile telephones on sperm quality: A systematic review and meta-analysis ☆

Mobile phones are owned by most of the adult population worldwide. Radio-frequency electromagnetic radiation (RF-EMR) from these devices could potentially affect sperm development and function. Around 14% of couples in high- and middle-income countries have difficulty conceiving, and there are unexplained declines in semen quality reported in several countries. Given the ubiquity of mobile phone use, the potential role of this environmental exposure needs to be clarified. A systematic review was therefore conducted, followed by meta-analysis using random effects models, to determine whether exposure to RF-EMR emitted from mobile phones affects human sperm quality. Participants were from fertility clinic and research centres. The sperm quality outcome measures were motility, viability and concentration, which are the parameters most frequently used in clinical settings to assess fertility. We used ten studies in the meta-analysis, including 1492 samples. Exposure to mobile phones was associated with reduced sperm motility (mean difference − 8.1% (95% CI − 13.1, − 3.2)) and viability (mean difference − 9.1% (95% CI − 18.4, 0.2)), but the effects on concentration were more equivocal. The results were consistent across experimental in vitro and observational in vivo studies. We conclude that pooled results from in vitro and in vivo studies suggest that mobile phone exposure negatively affects sperm quality. Further study is required to determine the full clinical implications for both sub-fertile men and the general population.
