Progesterone and Thyroid

Meaning

Progesterone and Thyroid refers to the crucial, bidirectional interaction between the primary female sex hormone, progesterone, and the thyroid hormones, T4 and T3, which collectively govern a vast array of metabolic and reproductive functions. This relationship is essential for overall endocrine homeostasis, as progesterone is known to influence thyroid hormone sensitivity at the cellular level, while thyroid status profoundly affects the synthesis and metabolism of progesterone. Clinically, an imbalance in one system, such as low thyroid function, can precipitate or exacerbate symptoms of progesterone deficiency or dominance, highlighting the need for a holistic approach to hormonal assessment.
