摘要
目的研究解脲脲原体感染与男性不育的关系,探讨解脲脲原体(ureaplasmaure-a-lyticum,Uu)引起男性不育的可能机制。方法用扫描电镜和免疫酶(PAP法)染色观察解脲脲原体感染的不育患者精子。结果Uu阳性精子在扫描电镜下可见部分精子的头、尾部有明显颗粒状物质吸附,而Uu阴性的精子上未见任何颗粒吸附。Uu在扫描电镜下多呈卵圆形和球杆状,单个、成双或呈链状排列,与吸附于精子上的颗粒相似。33份Uu培养阳性的精子涂片用抗Uu血清做PAP免疫酶染色,证明其中27份精子上(81.81%)有PAP阳性的棕黄色Uu颗粒吸附,而22份Uu阴性的精子涂片上未见任何PAP阳性的棕黄色颗粒。结论大部分精液经Uu感染后,Uu可吸附于精子的表面,使精子的负荷增加,运动阻力增大。
