title: [A comparative in vitro culture study of the action of the embryonic chick and rat testes on the embryonic chick Wolffian duct (author's transl)].
abstract: Embryonic chick and rat testes were cultured in vitro in combination with embryonic chick Wolffian ducts in order to compare their capacity for testosterone secretion. The rat testes stimulated the Wolffian ducts, whereas the chick testes did not. It is concluded that testosterone secretion of the embryonic chick testis is non-existent or negligible. This conclusion is in agreement with the findings of previous in vitro culture experiments. However, in the literature conflicting results were obtained by various authors when applying biochemical methods.
