However if this reversal process is defective organization of this material can occur which can lead to initially incomplete and then complete tubal obstruction as anatomical or functional obstruction without tubal wall damage .

但是，如果这种自我清除过程存在缺陷，之前形成的堵塞物将发生机化，而致使开始形成近端输卵管不全堵塞或完全堵塞，但不 伴有 输卵 管管 壁的损伤。

The tubal wall of spermatic duct is composed of mucosa muscular layer and adventitia .

输精管 管 壁由粘膜、肌层和外膜三层组成；

Pathological observation blank group : tubal wall organizational structure clear luminal patency mucosal layer of the visible rows of epithelial cells rich in cilia .

结果1.病理学观察空白组： 输卵 管管 壁组织结构清晰，管腔通畅，黏膜层可见排列整齐的上皮细胞，纤毛丰富。
