title: Testosterone metabolism and its testosterone-dependent activation in the uropygial gland of quail.
abstract: The in vitro metabolism in the uropygial gland of the male quail results into large yields of 5 beta-reduced and/or 17 alpha-hydroxylated metabolites. This metabolism was studied in glands of sexually quiescent quails five days after a single intra-muscular injection of testosterone to the birds. This treatment led to an increased production of inactive metabolites (epitestosterone and its 5 beta-reduced metabolites) and to a decrease of unmetabolized testosterone. Thus testosterone controls its own metabolism and by this way means to modulate its action in the uropygial gland of quail.
