Efferent ducts of Ambystoma dumerilii after spermiation. (A,B). Panoramic view of sections with 2 types of efferent ducts: transversal ducts (Td) and Wolffian ducts (Wd). The lumen of the Wolffian ducts contains abundant spermatozoa (z). Near the ducts, the periphery of both testes (T) is seen. Hematoxylin-eosin. Bar = 50 μm. Bar = 40 μm. (C,D). Details of the efferent ducts of Ambystoma dumerilii. Both types of ducts, transversal ducts (Td) and Wolffian ducts (Wd) have columnar epithelium (E). The epithelium of the transversal ducts presents long stereocilia (*) in the apical end. Wolffian ducts contain abundant spermatozoa (z). Connective tissue (ct) surrounds the ducts. Masson's trichrome. Bar = 20 μm. Bar = 10 μm.
