Resumo: The aim of the present study was to analyze the ultrastructural aspects of spermatogenesis in Phalloceros caudimaculatus, during cell proliferation. The parenchyma is organized morphologically as lobular restricted spermatogonial testis. Spermiogenesis in this species is characterized by four morphological stages of development (spermatids S1 through S4). The mature spermatids and spermatozoa heads are situated at the periphery of the cyst surrounded by the cytoplasm of the Sertoli cells. The germ cell's ultrastructure and spermatogenesis in P. caudimaculatus are very similar to that of other poeciliids.

El parénquima testicular está morfológicamente organizado como lobular espermatogonial restricto. La espermiogénesis en esta especie se caracteriza por cuatro etapas morfológicas de desarrollo (espermátidas S1 hasta S4). Las cabezas de las espermátidas maduras y espermatozoides están situadas en la periferia de los cistos, rodeados por el citoplasma de las células de Sertoli. La ultraestructura de las células germinativas y la espermatogénesis en P. caudimaculatus son muy similares a las de otros poecílideos.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação para o Desenvolvimento da UNESP (FUNDUNESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)São Paulo State Univ UNESP, Dept Biol Sci, Fac Sci, Bauru, SP, BrazilCAUNESP, Jaboticabal, SP, BrazilSão Paulo State Univ UNESP, Dept Biol Sci, Fac Sci, Bauru, SP, BrazilCAUNESP, Jaboticabal, SP, BrazilFAPESP: 97/2812-8CNPq: 300693/91-5Soc Chilena AnatomiaUniversidade Estadual Paulista (Unesp)Vicentini, Carlos Alberto [UNESP]Munoz, Mario EstebanFranceschini Vicentini, Irene Bastos2014-05-20T13:25:52Z2014-05-20T13:25:52Z2010-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article951-956application/pdfhttp://dx.doi.org/10.4067/S0717-95022010000300047International Journal of Morphology.
