Morphologic and morphometric sperm characteristics of mouse epididymal extracts from animals exposed to static magnetic fields were evaluated. For this purpose, animals were exposed for 35 days to a field of 0.7 T generated by a commercial permanent magnet for either 1 or 24 h per day. The values of morphometric parameters were obtained using the morphometric module of the Sperm Class Analyzer computerized image analysis system, and percentages of abnormalities were calculated. The size of sperm heads was unaffected by exposure to static magnetic fields. Lack of hook was a sperm head abnormality found significantly more frequently in animals exposed continually than in nonexposed animals, showing a possible alteration to the spermatogenic process after exposure to static magnetic fields. The percentage of sperm with coiled tails or of sperm with abnormal midpiece or tail was not altered by exposure.
对暴露于静磁场的动物附睾提取物的精子形态学和形态计量学特征进行了评估。为此，将动物每天暴露于由商用永磁体产生的0.7 T磁场中35天，每天暴露1小时或24小时。使用精子分类分析仪计算机图像分析系统的形态计量模块获得形态计量参数值，并计算异常百分比。精子头部大小不受静磁场暴露的影响。无钩是一种精子头部异常，在持续暴露的动物中比未暴露的动物中更频繁地被发现，这表明暴露于静磁场后精子发生过程可能发生了改变。暴露并未改变具有卷曲尾的精子或具有异常中段或尾部的精子的百分比。
