Evidence That Exteroceptive Stimuli Can Release Prolactin From The Pituitary Gland Of The Lactating Rat



Evidence That Exteroceptive Stimuli Can Release Prolactin From The Pituitary Gland Of The Lactating Rat



Endocrinology 76: 340-342



The litters of lactating rats were separated from their mothers for 10 hours on postpartum day 14. The concentration of prolactin in the anterior pituitary glands of the mothers was significantly reduced when the pups were replaced with the mothers for 30 min but were prevented from nursing by means of a wire screen placed between mother and litter. The reduction in prolactin was comparable in extent to that which occurred after 30 min of nursing. These results suggest that exteroceptive stimuli emanating from the young can cause the discharge of prolactin in the lactating rat.
