精子发生精子发生可分为精原细胞、初级精母细胞、次级精母细胞、精细胞、精子五个阶段。 - According to the changes of the structure of chromatin and the morphology of cell , the process of the typical spermatogenesis of cipangopaludina chinensis can be divided into five stages : spermatogonium , primary spermatocyte , secondary spermatocyte , spermatid and mature sperm
中国圆田螺典型精子发生时，根据染色质和细胞形态的变化，可将其发生分为以下五个时期：精原细胞、初级精母细胞、次级精母细胞、精细胞和成熟精子。 - There are five developmental stages in the spermatogenesis , namely are primary spermatogonium , secondary spermatogonium , primary spermatocytes , secondaty spermatocytes and spermatids . the spermatids develop into sperm via the process of spermiogenesis . there exist cell junctions between two spermatids
电子显微镜观察表明：大眼鳜的精子发生和形成过程，经历了初级精原细胞，次级精原细胞，初级精母细胞，次级精母细胞和精子细胞阶段。 - Nucleoli do not emerge in this process . the number of the organelles increase until secondary spermatocyte stage . mitochondria accumulate together , merging together with lysosomes and golgi bodies at the early spermatid stage , and finally the lamellar structure is formed , which forms the acrosome at last
在精子发生过程中，线粒体、内质网和核糖体逐渐增多，其中线粒体数目在次级精母细胞阶段达到顶峰，并形成线粒体区，精细胞早期核内出现膜性泡结构，同时次级溶酶体与高尔基体大量存在，这些细胞器共同形成片层复合体，并参与顶体的形成。 - Spermal ultrastructure the sperm ultrastructure of the macrobrachium rosenbergii and exopalarmon carinicanda holthuis analogical , the whole sperm looks like a inversed umbrella , it has a main body , a spike and a little bit cytoplasm . there are some vesicle exist in the m . rosenbergii sperm nucleus . the relatively length of the spike of the e
各种细胞器数量在精子发生过程中逐渐增多，其中内质网以粗面内质网为主，线粒体于初级精母细胞阶段始出现，膜轮结构在次级精母细胞中出现，精细胞早期的上述细胞器分化成电子密度高的前顶体腔，并逐渐分化形成方形顶体。
