精索静脉曲张不育症患者睾丸、附睾组织的超微结构改变

Ultrastructure changes of the testes and epidymis in infertile men with varicocele

为了探索精索静脉曲张在男性不育中的作用，本文应用电镜观测25例精索静脉曲张不育症患者的睾丸和附睾组织的超微结构改变．镜下可见生精细胞脱落，间质小血管病变和对侧睾丸的病理损害是精索静脉曲张不育症睾丸组织的三种主要病理改变，其中间质小血管病变更具有特征性．电镜观察发现精原细胞存在明显的超微结构变化是精索静脉曲张不育症患者精子生成障碍、精原细胞增殖、精母细胞成熟分裂和细胞变态的主要原因．

The ultrastructural change of the testes and spidymis from 25 infertile men with varicocele was observed by electron miscoscopy The exfoliation of germ cells, the impairment of interstitint small blood vessels and the pathological alteration in the contralateral testcs were three main pathological changes observed, among which the interstitial small blood vessel imparment might be most characeristic. The main cause of dyszoosperma spermatogonium, prolifetalive spermatogonium. spermatocyte maturation division and cell matamorphosis lay in the obvious ultrastrucure change in the spermatogonium.
