Interaction of cells of Wolffian duct and mesothelium during initial growth period of mullerian ducts in the axolotl (Ambystomamexicanum).
Due to the presence of both Mullerian and Wolffian ducts on laparoscopic paraovarian and paratubal cyst biopsy, the current case was evaluated as 46,XY ovotesticular DSD.
The internal (Miillerian and Wolffian) structures are also sexually dimorphic, but these are not evaluated in most newborns.
The internal genitalia are variable, often with a mixture of Mullerian and Wolffian duct structures.
A quite common differential diagnosis of acute scrotum in young children is torsion of the testicular or epididymal appendages, which are embryologic remnants of the Mullerian or Wolffian ducts, respectively.
In normal embryological development, the epididymis and vas deferens arise from the Wolffian duct [3].
It is true that the exact etiology of such anomalies is still unknown, but it has been established that they have their origin in a mesonephric (Wolffian duct) anomaly.[sup][2] The mesonephric anomaly with the absence of the Wolffian duct opening into the urogenital sinus and therefore of the ureteral bud sprouting, justifies the blind vagina and unilateral renal agenesis.
Female Assignment Removal of intrabdominal testis or streak gonads, removal of Wolffian structures and testicular tissues.
However, it is a matter of controversy if the oligochaetes Dero (Allodero) recorded in the ureters, Wolffian ducts, and bladder of anurans--including many treefrogs from tropical regions in the Americas, Africa, Asia, and Australia--are parasites, endocommensals, or symbionts (Harman, 1971, 1973; Harman and Lawler, 1975; Pinder et al., 1998).
The upper Wolffian ducts fail to develop, so no internal male organs are present.
