A research on the action of testosterone propionate and of ciproterone acetate on the mouse-killing behaviour of the adult rat.
Data demonstrate exactly that testosterone favour above all the killing behaviour of castrate males at birth in comparison with control males while ciproterone acetate turns out to be more effective in diminishing the killing behaviour of males having integral testicle and of androgenized females at birth in comparison with castrated males. The results point out that the killing behaviour of rats is affected by the presence of testosterone in the first days of life, and in the grown-up animal.
