氩离子激光凝堵输精管后睾丸附睾的形态学观察

THE MORPHOLOGIC STUDY OF TESTIS AND EPIDIDYMIS AFTER VAS DEFERENS OCCLUSION WITH ARGON LASER

对氩离子（Ａｒ＋）激光凝堵输精管后不同时期的睾丸和附睾做了形态学观察，发现在术后半月，无论在肉眼和镜下睾丸和附睾均无明显变化；术后１个月，附睾出现淤积现象；２～３个月后，睾丸肉眼形态无明显改变，镜下睾丸部分曲细精管生精细胞萎缩，肉眼观附睾体积增大，镜下输出小管和附睾管扩张，个别标本间质内有精子性肉芽肿形成；术后６个月或更长时间，睾丸和附睾的变化基本同前。提示氩离子激光凝堵输精管后，部分睾丸生精细胞萎缩并附睾精子肉芽肿形成是影响复孕的两个因素。

The morphologic changes of testis and epididymis at different intervals after the vas deferens occlusion with Ar + laser were observed.It was found that there were no obvious morphologic changes of testis and epididymis under naked eye and optical microscope a half month after the operation.Sperms were congested in epididymis one month after operation Two to three months later,the testis was normal with naked eye examination,but parts of the spermatogenic cells of seminiferous tubule were atrophied.The volume of epididymis was increased and efferent ductules and ductus epididymidis were dilated.Spermatic granuloma in the stroma of epididymis formed in individual specimens.Six months or longer after operation,the changes of testis and epididymis were the same as they were before.No obvious changes were noted in supporting cells and leydig cells of the testis.It is suggested that spermatogenic cell atrophy and spermatic granuloma formation are two factors influencing the repregnancy.
