Interbular space characterization in adult capybara (Hydrochoerus hydrochaeris) testis
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 %...

| description | 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 arrangement of the components in intertubular tissue was similar to pattern I of Fawcett's classification as was found in guinea-pigs and chinchillas.<br>Objetivou-se com esta pesquisa caracterizar qualitativamente e quantitativamente os diferentes componentes do tecido intertubular de capivaras machos adultas. Utilizou-se testículos de 15 capivaras adultas, provenientes de um abatedouro comercial de animais silvestres. Encontrou-se um percentual médio de células de Leydig de 32,95+10,03%, dos demais componentes do espaço intertubular de 14,95+4,79% e um total de espaço intertubular de 47,91+11,48%. O peso médio dos testículos foi de 32,83+4,78g, o peso corporal dos animais foi em torno de 52,37kg e os índices gonadossomático e leydigossomático foram, respectivamente, 0,125+0,02% e 0,0411+0,0148%. Concluiu-se que o índice leydigossomático das capivaras é menor que o observado em ratos e que o arranjo dos componentes do tecido intertubular é semelhante ao descrito como padrão tipo I da classificação de Fawcett, similar ao encontrado em cobaios e chinchilas. |
