Low Progesterone

Meaning

Low Progesterone describes a clinical finding where the circulating concentration of the primary corpus luteal hormone, progesterone, falls below established physiological reference ranges for a given phase of the menstrual cycle or life stage. This deficiency significantly impacts endometrial health, thermoregulation, and neurosteroid balance, often leading to symptoms like anovulation or increased anxiety. Recognizing this imbalance is central to reproductive and mood stabilization protocols.
