[Binding capacity of the testosterone-binding plasma protein in 2 wild mammals with cyclic testicular activity, the fox and badger].
The binding capacity of the plasma testosterone binding globulin (TeBG) as determined by the equilibrium dialysis method, in fox and badger, was shown to wary in relation to the seasonal endocrine activity of the testis. During the winter breeding period, the TeBG binding capacity was low in the fox and high in the badger, whereas an opposite situation prevailed during the sexual quiescence phase. Independent of those seasonal variations, the binding capacity of TeBG was always lower in fox than in badger.
