东方扁虾雄性生殖系统的解剖学和组织学研究

东方扁虾雄性生殖系统由精巢、输精管及雄性生殖孔三部分组成，输精管可分为前、中、后三段。精巢由卷绕的前、后收集管及持靠其上的许多生精腺囊所组成。同一腺囊内的精细胞发生基本同步，而不同腺囊内则可以不同步。收集管的主要功能是将精细胞团输送至输精管。精荚在输粗管内运行时一直进行着精子的形成过程，直至精子成熟。位于输精管末段不肌层外的索带状细胞团被认为是造雄腺。

Anatomical and Histological Studies on the Male Reproductive System of Thenus orientalis

The male reproductive system of Thenus orientalis is composed of paired testes, vas deferens and male gonopores. The vas deferens can be separated visually into the anterior, medial, and posterior segment. The testes are composed of multi\|convoluted anterior and posterior collecting tubules bearing numerous spermatogenic acini. Stages of spermatocyte development within the acini vary throughout the testis; however spermatogenesis within each acinus is usually synchronous. The main function of collecting tubules is to transport the spermatids to the vas deferens. Spermiogenesis continues as the spermatophores progress through the vas deferens until sperm maturity is reached. The broad cords of cells lie outside the out circular muscular layers of the terminal vas deferens may be the androgenic gland of T.orientalis.
