Morfofisiologia do tecido intertubular e das células de Leydig de jaguatirica (Leopardus pardalis) adulta

The aim of this study was to do a quantitative investigation of the intertubular space and describe its arrangement in adult ocelots (Leopardus pardalis). In this experiment we used testicular fragments, obtained through biopsy from five adult ocelots maintained in captivity. The intertubular compartment corresponded to 19.4% of the testicular parenchyma, and 3.9% of this compartment was occupied by Leydig cells. The Leydig cells showed to be uninucleate, with rounded nuclei and single nucleoli, with a large amount of pigment granules in their cytoplasm. The intertubular compartment showed a clear pattern of type II and the conjunctive tissue was the most abundant component of the intertubular tissue. Despite the small unit volume of Leydig cells in adult ocelots, the average number per gram of testis (33.39 x106) was within the range described for most mammals.
