摘要：

隆线溞雄性生殖系统由一对精巢、一对输精管和一个雄性生殖孔组成。精巢呈腊肠形，管壁由结缔组织膜和生殖上皮构成。输精管呈细直管状，末端膨大，管壁以结缔组织膜为主。雄体的生殖细胞发生经历精原细胞、初级精母细胞、次级精母细胞、精子细胞和成熟精子五个时期。成熟精子呈棒状。精子群的发生具有同步化趋势。雄体的性成熟一般经历四个龄期。隆线溞雄性生殖系统在结构与功能上表现出相对的原始性和适应性，两者相互结合，使以隆线溞为代表的枝角类更能适应复杂多变的生活环境。

Abstract: The male reproductive system of Daphnia (Ctendaphnia) carinata is composed of a pair of testes, deferens and one male gonopore. The wall of the sausage-shaped testis is composed of connective tissue and germinal epithelium inside. The tube-shaped deferens, which gets larger at the end of it, is mainly made up of connective tissue. The spermatogenesis includes five stages: spermatogonium、primary spermatocyte、secondary spermaticyte、spermatid and spermatozoon. The mature sperm is clubbed and the spermatogenesis shows a tendency of synchronization. The sexual maturation experiences four stages. The male reproductive system retains its primative characters on structure and function, but it has also made up its adaptability through the long-time evolution, which enables Daphnia (Ctendaphnia) carinata and other species of Cladocera to live with the changeable living environment.
