Abstract：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 .
