Resumo: | Body and testicular biometric parameters are very important for establishing reproductive patterns and, consequently, the development of protocols for assisted reproduction in different species. A direct correlation between the testis weight and the sperm population was observed in other studied species, because the testis size primarily reflects the total volume of the seminiferous tubule, its main component. The objective of this study was to determine the testicular volume parameters and correlate data from morphometry of testis and seminiferous tubules with body mass in six adult crab-eating foxes. The mean body weight of the crab-eating foxes in this study was 6.53 kg, with approximately 0.068% allocated to the testicular mass and 0.042% specifically to seminiferous tubules, which represented 87.5% of the testicular parenchyma. The albuginea comprised 12.5% of the testicular mass. The mean diameter of seminiferous tubules was 236 µm, and the mean thickness of the seminiferous epithelium was 62.9 µm. Values of tubular parameters indicate a sperm productivity close to those observed in previously studied carnivores. |

Uma correlação direta entre o peso do testículo e a população espermática é observada nas diferentes espécies já estudadas, uma vez que o tamanho do testículo reflete principalmente o volume total do túbulo seminífero, seu principal componente. O presente trabalho tem como objetivos definir parâmetros volumétricos testiculares e correlacionar os dados de morfometria testicular e do túbulo seminífero com a massa corporal em seis cachorros-domato adultos. O peso corporal médio dos cachorros-do-mato foi de 6,53 Kg, dos quais cerca de 0,068% são alocados em massa testicular e 0,042% especificamente em túbulos seminíferos, que representam 87,5% do parênquima testicular. A albugínea representa 12,5% da massa testicular. O diâmetro médio dos túbulos seminíferos em cachorro-do-mato foi de 236 µm, e a espessura média do epitélio seminífero foi de 62,9 µm, sendo encontrados em média 18 metros de túbulo seminífero por grama de testículo. Os valores para os parâmetros tubulares indicam uma produtividade espermática próxima àquelas observadas nos carnívoros já estudados.Revista Ceres2018-03-12T10:28:34Z2018-03-12T10:28:34Z2010-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf2177-3491http://dx.doi.org/10.1590/S0034-737X2010000500001http://www.locus.ufv.br/handle/123456789/18162engv. 57, n. 5, p. 569-575, set/out 2010Caldeira, Bianca CabralPaula, Tarcízio Antônio Rêgo deMatta, Sérgio Luis Pinto daBalarini, Mayte KochCampos, Pamella Kelly Araújoinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:11:52Zoai:locus.ufv.br:123456789/18162Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:11:52LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
