Progesterone 161-173 proopiomelanocortin Homo sapiens 93-97 18697912-9 2008 With 0.5 mg x kg(-1) x day(-1) cortisol, plasma ACTH levels were greater in pregnant ewes than in nonpregnant ewes with or without progesterone. Progesterone 131-143 proopiomelanocortin Homo sapiens 48-52 18697912-12 2008 We conclude that increased progesterone does not alter the feedback relation of cortisol to ACTH, but may modulate ACTH indirectly through plasma volume. Progesterone 27-39 proopiomelanocortin Homo sapiens 115-119
