Behavioural and physiological effects of testosterone propionate and cyproterone acetate in immature male domestic ducks, Anas platyrhynchos. 1978

J Balthazart

The behavioural and morphological effects of testosterone propionate and of the antiandrogen cyproterone acetate were studied in male domestic ducks. Testosterone was also measured by radioimmunoassay in the plasma of these birds to relate the behaviour to the actual circulating levels of hormone. Testosterone stimulates sexual behaviour but has few effects on social displays. There is no correlation between the individual variations of plasma testosterone and sexual behaviour.

D003534	Cyproterone	An anti-androgen that, in the form of its acetate (CYPROTERONE ACETATE), also has progestational properties. It is used in the treatment of hypersexuality in males, as a palliative in prostatic carcinoma, and, in combination with estrogen, for the therapy of severe acne and hirsutism in females.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000829	Animals, Domestic	Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.	Farm Animals,Domestic Animals,Domesticated Animals,Animal, Domestic,Animal, Domesticated,Animal, Farm,Animals, Domesticated,Animals, Farm,Domestic Animal,Domesticated Animal,Farm Animal
