Abstract: Seventy-two spayed crossbred ewes were used in a series of five successive tests, at intervals of 15 days, in a study of the actions and interactions of androgen, oestrogen and progesterone on behavioural and vaginal oestrous responses. Androgen and oestrogen were additive in their action (128 vs. 62 services; P<0·001) on behavioural response, but androgen almost completely inhibited the expected vaginal response to oestrogen. There was a significant linear decline in behavioural sensitivity from test to test; in the five successive tests, forty-eight, forty-three, thirty-seven, thirty-two and thirty ewes were served (P<0·001). This refractory condition was partly offset by progesterone pretreatment (P<0·001), but oestrogen was necessary to maintain a constant state of psychic reactivity to androgen (P<0·001). A highly significant linear dose-response relationship was demonstrated with both testosterone and testosterone propionate (P<0·001). |
