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.
