“…Van Erp Taalman Kip (1894) described as early as 1894 cases in mice and moles where the infundibulum and müllerian duct are both present, but not in continuity. In women, an infundibulum and a short portion of the oviduct can be observed, even when the caudally following derivatives of the müllerian duct are absent (Menge and von Oettingen 1930). Following experimental exstirpation of the wolffian duct in birds, no müllerian duct proper will develop, whereas its cranial ostium region is regularly formed (Jacob et al 2000).…”

The development of the müllerian duct was studied in a total of 85 specimens of Acipenser ruthenus and Acipenser baeri in the period from 7 days after hatching through 5 years of age. Normal histology on serial sections, transmission and scanning electron microscopy and bromodeoxyuridine immunohistochemistry were applied. In Acipenser, the primary set of opisthonephric nephrons possess short nephrostomial tubules with well-developed nephrostomes. Proliferating cells from the lateral side of the slightly protruding nephrostomial lips spread out over the ceolomic surface, replace here the flat mesothelium of lateral plate origin and establish the infundibular field, consisting of cuboidal or columnar cells. At about 28 days after hatching, the primordium of the müllerian infundibulum becomes visible in the form of a pocket-like invagination within the infundibular field. This invagination is found coexisting with and located laterally to the line of intact nephrostomes. The müllerian infundibulum, therefore, does not represent the homologon of a nephrostome itself, but must be regarded as a separate and secondary structure. The müllerian duct proper has its origin in cells from the bottom of the infundibular pocket. These cells grow as a tubule with a solid tip in the caudal direction, paralleling the wolffian duct, but without a contribution of cells from the latter. In Acipenser, a müllerian duct is present also in the adult male. In males as in females, the caudal extremity of the müllerian duct generally divides into two to three smaller terminals which end in the wolffian duct at different levels, but always cranial to the urogenital sinus. In most indifferent animals and in all males of this study, the tips of the müllerian terminals are closed and covered by a thin layer of wolffian epithelium. In adult females, the müllerian ducts end with open terminals. In both sexes, the adult müllerian duct is lined by a pseudostratified columnar epithelium, consisting of ciliated, non-ciliated and basal free cells.
