Prolactin Secretion Timing

Meaning

Prolactin Secretion Timing refers to the predictable, rhythmic pattern of prolactin release from the anterior pituitary gland, which is primarily characterized by a nocturnal surge, peaking during the early morning hours of sleep. While often associated with reproductive function, prolactin also plays roles in immune regulation, stress response, and metabolic function. Understanding and maintaining this specific timing is clinically relevant because chronic elevation or disruption of the nocturnal peak can signal underlying pituitary dysfunction or contribute to reproductive and metabolic disturbances.
