摘 要:电镜观察37例无精子症睾丸组织,就超微结构特点,按曲细精管有无精子形成,精子数量多少以及生精细胞形态特征分为三类:①睾丸曲细精管有精子形成,且数量不少,生精细胞的数量、排列及形态结构也基本正常。②曲细精管也有精子形成,但数量明显减少,生精细胞及其精子结构常常出现多种退行性变或畸形。③曲细精管未见精子生成。此类又可分为4亚类:a)生精上皮中有精原细胞和精母细胞,但无精细胞与精子;b)生精细胞未发育,生精上皮只有支持细胞;c)生精上皮的细胞溶解坏死;b)睾丸组织无曲细精管。最后,对三类无精子症作了临床分析.Electron microscopy of testicular tissue in 37 cases of azoospermia are reported Azoospermia may be divided into three different types according to whether there are any spermatozoa developed in the seminiferous tubules, and based on the number of spermatozoa and the ultrastructural characteristics of the spermatogenic cell and spermatozoon. 1. There are enough spermatozoa developed within the testicular seminiferous tubules, the number of spermatogenic cells, their arrangement and morphological structure are essentially normal. 2. There are spermatozoa developed in the seminiferous tubules,but their number is obviously decreased, the spermatogenic cell and the structure of spermatozoa often present several changes of retrogression or de-formity. 3. No spermatogenesis appears in the seminiferous tubules, and this type may be further divided into four subdivisions <a> There are spermatocytes, but nospermatid and spermatozoa; <b> The spermatogenic cells are underdeveloped, there are only sertoli cells; <c> The seminiferous epithelial cells are dissolved and necrosed; <d> There are no seminiferous tubules in the testicular tissue. Clinical analysis of these three types of azoospermia is given.
