[Study of the testosterone action on quail and chick müllerian ducts in "in vitro" culture (author's transl].
Right and left müllerian ducts of 6 to 9 days old chick embryos, 7 to 9 days old quail embryos and left differentiated ducts of chick embryos to 10 to 19 days of development are explanted on medium with testosterone. In "in vitro" culture, this hormone is able to provoke regressive phenomenons and the complete disapearance of müllerian epithelium; only a mensenchyme string subsists similarly to that observed "in ovo" during the involution of these gonoducts in the male embryos. The müllerian epithelial cells of the 19 days old female embryos undergo a quick autolysis. The action is selective, neither the Wolffian duct nor the mesonephros are attaqued.
