MORPHOLOGICAL OBSERVATIONS ON THE TESTES OF Physalaemus cuvieri (AMPHIBIA, ANURA)

In general, the testes in the anurans are paired ovoid organs, constituted by a mass of seminiferous structures surrounded by a layer of fibrous connective tissue, which holds a germ epithelium with characteristic cellular types. This study describes the testicular histological architecture and anat...
