title: [Hormones and development of sexual behaviour in the domestic sheep (author's transl)].
abstract: All motor patterns of male sexual behaviour can be observed in young lambs from the first days of the life. They considerably increase on weeks 2 to 5 when they decrease dramatically and remain stable up to over 6 months of age. This evolution has no direct relation with that of the physiological events. The adult female has a complete bisexual potentiality. The development of the sexual behaviour during ontogeny appears as a continuous process rather than to be limited to the period of puberty or sexual differentiation.
