The pygmy males of Chondracanthus angustatus are fixed on the genital segment of the female on two anterior-ventral tubercules. The genital system is formed by two dorsal testes, two broad vas deferens and two seminal vesicles each one containing a spermatophore. Two types of cells can be seen in the interstitial tram: the sexual (normal and abortive) and the somatic ones. The plasmic and nuclear membranes joined together on one end of the spermatid; on the opposite pole, the mitochondria penetrate into the cytoplasmic expansions. The non-motile starfish spermatozoa present neither di-ferentiated acrosome nor centrioles. The male gametes are stocked in the spermatophore and enveloped by many kinds of secretions. Spermatozoa are discharged into the female integument folds and they reach the seminal receptacle with the help of the villosities movement; they stay there till fertilization occurs.
窄角软骨鱼的侏儒雄鱼固定在雌鱼生殖节的两个前腹侧瘤上。生殖系统由两个背侧睾丸、两条宽阔的输精管和两个精囊组成，每个精囊都含有一个精荚。在间质组织中可以看到两种类型的细胞：性细胞（正常和异常）和体细胞。精细胞一端的质膜和核膜相连；在相对的极，线粒体穿透到细胞质延伸部分。不能游动的海星精子既没有分化的顶体也没有中心粒。雄配子储存在精荚中，并被多种分泌物包裹。精子被排放到雌鱼的体表褶皱中，并借助绒毛的运动到达受精囊；它们停留在那里直到受精发生。
