摘要
目的研究50Hz极低频磁场暴露对成年男性精子活力、活动力参数和精液酸碱度的影响。方法将成年健康男性新鲜精液标本分别暴露于0．4mT、50Hz正弦磁场中15、30、60rain，采用WUY-9000型伟力彩色精子质量检测系统动态记录精子活力、活动力参数并测定精液酸碱度。结果新鲜精液标本暴露于50Hz磁场中15min，可使精子活力（a＋b级精子）和精子活动率（a＋b＋c级精子）均呈抑制状态，与平行对照组相比，差异有统计学意义（P〈0．01）；暴露30min，两组问精子活力和精子活动率差异无统计学意义（P〉0．05）；暴露60min后，精子活力和活动率又呈抑制状态，与平行对照组相比，差异有统计学意义（P〈0．01，P〈0．05）。然而，相同参数的磁场暴露15、30、60min，对精液酸碱度无明显影响。结论暴露于0．4mT、50Hz的正弦磁场中不会影响男性精液的酸碱度，但可明显抑制精子的活力和活动率。
Objective To study the effects of 50-Hz extremely low frequency electromagnetic field （ELF-EMF） exposure on the pH of the adult male semen and the motoricity and motoricity parameters of spermatozoa. Methods Healthy adult male fresh semen was exposed to a 50-Hz EMF at 0.4 mT for 15, 30 and 60 min, respec- tively. The pH value of the semen, the motoricity and motoricity parameter of spermatozoa were detected and recorded in real time using the WLJY-9000 pattern chromatic color spermatozoa quality detection system. Results Compared with parallel control group, the exposure of adult male fresh semen to a 50-Hz EMF at 0.4 nat for 15 minor 60 min could decrease significantly the motoricity （spermatozoa with a＋b lever） and the activity ratio （sperma- tozoa with a＋b＋c lever） （P〈0.O1）. However, there were no significant differences of motoricity and the activity ratio between exposure group and control group （P〉0.05）, and after exposure to a 50-Hz. EMF for 30 min the motoricity and the activity ratio of exposure group were inhibited, as compared with control group （P〈O.O1 or P〈0.05）. The pH value of the semen was not obvious changed （P〉0.05）when semen was exposed to a 50-Hz EMF of 0.4 mT for 15, 30 and 60 min. Conclusion In present experiment, it is suggested that the exposure of adult male fresh semen to a 50-Hz EMF in vitro could inhibit the motoricity and the activity ratio, but not affect the pH value of the semen within 60 min.
