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。
