为促进卵胎生鱼类的养殖和选育，应用石蜡切片技术对卵胎生硬骨鱼红玛丽雄性生殖器官组织结构和精子发生过程进行了研究。红玛丽雄性生殖器官包括精巢、贮精囊、输精管和交接器。成鱼精巢属小管型结构，每个精小管中的生精细胞发育同步。精巢后端通过输出管与贮精囊相连，左右两个贮精囊汇集成一条共同的输精管。红玛丽精子发生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、精细胞和精子6个时期。红玛丽精子的发生是连续的，精子成熟后以精荚形式输入雌鱼输卵管，保证了受精作用成功率。

The histological structure of male reproductive organs and spermatogenesis in ovoviviparous teleost sailfin molly ,Poecilia latipinna ,was studied by paraffin biopsy technology to promote the farming and cultivation of the ovoviviparous fish .The male reproductive organs of the sailfin molly were made up of lobular testis , seminal vesicle , vas deferens and mating organ . Within a seminiferous tubule , all spermatogenic cells were developed synchronously ,and the seminal vesicle was connected to posterior end of the testis with vas deferens .Left and right seminal vesicles converged together to a vas deferens .The spermatogenesis developed continuously through six phases as following :primary spermatogonium , secondary spermatogonium ,primary spermatocyte ,secondary spermatocyte ,spermatid and sperm .The fertilization rate was increased by the procedure that mature sperm was transported into the oviduct by a male ,forming spermatophores .
