The increased use of mobile phones, the media's attention for general health, and the increase of idiopathic male infertility suggest to investigate the possible consequences of an excessive use of mobile phones on semen quality.
To evaluate the conventional and some of the main biofunctional sperm parameters in healthy men according to the different use of the mobile phone.
All the enrolled subjects in this study were divided into four groups according to their active cell phone use: group A= no use (no.=10 subjects); group B= <2 h/day (no.=16); group C= 2-4 h/day (no.=17); and group D= >4 h/day (no.=20). Among the subjects of the group D (>4 h/day), a further evaluation was made between the "trousers users"(no.=12) and "shirt users"(no.=8), and they underwent semen collection to evaluate conventional and biofunctional sperm parameters (density, total count, morphology, progressive motility, apoptosis, mithocondrial membrane potential, chromatin compaction, DNA fragmentation).
None of the conventional sperm parameters examined were significantly altered. However, the group D and the trousers users showed a higher percentage of sperm DNA fragmentation compared to other groups.
These results suggest that the sperm DNA fragmentation could represent the only parameter significantly altered in the subjects who use the mobile phone for more than 4 h/day and in particular for those who use the device in the pocket of the trousers.
手机使用量的增加、媒体对一般健康的关注以及特发性男性不育症的增加,提示我们需要研究过度使用手机对精液质量可能产生的影响。
根据手机使用方式的不同,评估健康男性的常规和一些主要的精子生物功能参数。
本研究的所有受试者根据其手机的活跃使用情况分为四组:A 组=不使用(n=10 例);B 组<2 小时/天(n=16 例);C 组=2-4 小时/天(n=17 例);D 组>4 小时/天(n=20 例)。在 D 组(>4 小时/天)的受试者中,进一步对“穿裤子的使用者”(n=12)和“穿衬衫的使用者”(n=8)进行了评估,并进行了精液采集,以评估常规和生物功能的精子参数(密度、总计数、形态、前向运动、凋亡、线粒体膜电位、染色质浓缩、DNA 碎片化)。
所检查的常规精子参数均无明显变化。然而,D 组和穿裤子的使用者与其他组相比,精子 DNA 碎片化的比例更高。
这些结果表明,在每天使用手机超过 4 小时的受试者中,特别是在将手机放在裤子口袋中使用的受试者中,精子 DNA 碎片化可能是唯一明显改变的参数。
