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 morphology of testis and epididymis in different periods after argon ion (Ar +) laser coagulation and vasectomy was observed. There was no significant change in testis and epididymis both in macroscopic and microscopic examination after 1 month and 1 month after operation. 2 to 3 months later, there was no significant change in the morphology of testicular macroscopy. Microscopically, testicular seminiferous tubules showed atrophy of spermatogenic cells, enlargement of epididymal volume in macroscopic view, dilation of tubule and epididymal canal under microscope, The quality of the formation of sperm granuloma; 6 months or more after surgery, testicular and epididymal changes basically the same as before. Tip argon ion laser coagulation vas deferens, some testicular atrophy of spermatogenic cells and epididymal sperm granuloma formation is the impact of pregnancy two factors.
