Interbular space characterization in adult capybara (Hydrochoerus hydrochaeris) testis BABT
Paula,Tarcízio Antônio Rego de; Matta,Sérgio Luiz Pinto da; Silva Jr.,Valdemiro Amaro da; Costa,Deiler Sampaio; Fonseca,Cláudio Cesar; Neves,Marco Túlio David das.
This study aimed at the qualitative and quantitative characterization of the different intertubular tissue components in adult male capybara. Testes of 15 adult capybaras from a commercial slaughterhouse of wild animals were used. The average percentage of Leydig cells was 32.95 ± 10.03 %, whereas in the other components of the intertubular space it was 14.95 ± 4.79 %, thus the whole intertubular space totalized 47.91 ± 11.48 %. The average weight of the testes were 32.83 ± 4.78g, while the animals' body weight were around 52.37 kg and the gonadosomatic and leydigosomatic indexes were 0.125 ± 0.02% and 0.0411 ± 0.0148% respectively. It was concluded that the leydigosomatic index of the capybaras was lower than the one observed in rats, as well as the...

Cat, cougar, and jaguar spermatogenesis: a comparative analysis BABT
Costa,Deiler Sampaio; Paula,Tarcízio Antônio Rêgo; Matta,Sérgio Luiz Pinto da.
This work presents a comparative review about the spermatogenic process in cats (Felis domestica), jaguars (Panthera onca) and cougars (Puma concolor), with emphasis on testicular biometry, gonadossomatic index, volumetric proportion of testicular parenchyma components, tubular diameter, seminiferous epithelial height and seminiferous tubule length. It was an approach of the differences among the cell proportions that allowed conclusions about the overall yield of spermatogenic process and Sertoli cell index in three feline species.
