Interbular Space Characterization in Adult Capybara (Hydrochoerus hydrochaeris) Testis

摘要

This study aimed at the qualitative and quantitative characterization of the different intertubular tissue componentsin 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 intertubularspace it was 14.95 +- 4.79 %, thus the whole intertubular space totalized 47.91 +- 11.48 %. The average weight of thetestes were 32.83 +- 4.78g, while the animals' body weight were around 52.37 kg and the gonadosomatic andleydigosomatic indexes were 0.125 +- 0.02% and 0.0411 +- 0.0148% respectively. It was concluded that theleydigosomatic index of the capybaras was lower than the one observed in rats, as well as the arrangement of thecomponents in intertubular tissue was similar to pattern I of Fawcett's classification as was found in guinea-pigsand chinchillas.
