本文观察了溶脲脲原体（Ｕｒｅａｐｌａｓｍａｕｒｅａｌｙｔｉｃｕｍ，Ｕ．Ｕ．）对ＳＤ雄性大鼠睾丸的形态学影响。结果表明，在４０例膀胱内接种Ｕ．Ｕ．（１０５ＣＣＵ／ｍｌ）的大鼠中，有２５例睾丸中分离出Ｕ．Ｕ，动物睾丸重量减轻。光镜下可见１１例动物呈广泛的曲精小管萎缩，生精细胞严重脱落。部分曲精小管仅见支持细胞和少量精原细胞，有的仅剩下界膜。在曲精小管中发现许多多核巨细胞，有多核巨细胞处，生精上皮破坏更为明显，间质渗出、水肿。电镜观察发现，Ｕ．Ｕ．可吸附或侵入生精细胞内，造成生精细胞胞浆空泡化乃至崩解，部分线粒体基质空泡化或嵴消失。其余１４只大鼠睾丸组织有局灶性破坏。
This article investigates the morphological effects of Ureaplasma urealyticum (U.U.) on the testes of SD male rats. The results showed that in 40 cases of bladder inoculation U. U. (105 CCU / ml) of rats, 25 cases of testis isolated U. U, animal testicles weight loss. Light microscope, 11 cases of animals showed a wide range of atrophy of the seminiferous tubules, spermatogenic cells severely shed. Part of the seminiferous tubules only see supporting cells and a small amount of spermatogonia, and only the remnants of the membrane. In the seminiferous tubules found in many multinucleated giant cells, multinucleated giant cells, the destruction of seminiferous epithelium is more obvious, interstitial exudate, edema. Electron microscopy found that U. U. Can be adsorbed or invaded spermatogenic cells, resulting in cytoplasm spermatogenic cells vacuolization and disintegration, some mitochondrial matrix vacuolar or disappeared. The remaining 14 rats had focal destruction of testicular tissue.
