Module 3 — Prolactin Insufficiency
Prolactin plays a critical role in milk production regulation, yet prolactin insufficiency and impaired hormonal signaling are often overlooked in low milk supply cases.
In this module, we’ll explore prolactin physiology, baseline prolactin patterns, prolactin response dynamics, contributing factors that may impair signaling, and clinical considerations when evaluating hormonal influences on milk production.
We’ll also discuss how prolactin insufficiency may present clinically, why some patients fail to respond to traditional lactation interventions, and the importance of understanding both baseline prolactin levels and prolactin surge response patterns.
Please move through the lesson slides first, follow along with the downloadable companion guide, and complete the knowledge check at the end of the module before progressing further through the system.
Estimated Completion Time: 45–60 minutes

Module Reflection
Before moving forward to the knowledge check, take a moment to reflect on the patterns and concepts discussed throughout this module.
Consider:
• The difference between baseline prolactin levels and prolactin response dynamics
• Clinical patterns that may suggest impaired prolactin signaling
• Hormonal and physiological factors that may contribute to prolactin insufficiency
• Why low milk supply is not always solely a milk removal issue
• The importance of evaluating root-cause hormonal influences in complex lactation cases
Module 3 Knowledge Check
Please complete the following knowledge check before continuing to the next module.
This assessment is designed to reinforce understanding of the key concepts discussed throughout the lesson, including prolactin physiology, hormonal signaling, prolactin response dynamics, and clinical considerations surrounding prolactin insufficiency and low milk supply.
