Abstract: | Progesterone treatment failed to significantly depress activity-wheel activity elicited by food deprivation in either ovariectomized or ovariectomized estrogen-treated rats. These results indicate: (1) that the lack of effect of progesterone on the activity of ovariectomized rats is not due only to their already low level of activity; and (2) that the depressant effect of progesterone on activity in the estrogen-treated ovariectomized rat is, to a large extent, a specific inhibition of estrogen facilitation of activity, rather than a nonspecific activity depressant effect. |
