What is the Origin of Perimenopause Progesterone Therapy?

This therapeutic approach emerged from a deeper understanding of the specific endocrine changes during perimenopause, specifically the early decline in progesterone production despite often still-high estrogen levels. The term links the life stage, "perimenopause," with the specific hormone, "progesterone," and the clinical intervention, "therapy." It is a foundational strategy in managing the early, often symptomatic, stages of the female endocrine aging process.

What is the Mechanism of Perimenopause Progesterone Therapy?

Progesterone therapy works by binding to progesterone receptors in target tissues, particularly the uterus and the brain. In the uterus, it counteracts the proliferative effects of unopposed estrogen, preventing endometrial hyperplasia. In the central nervous system, progesterone's neurosteroid metabolites, such as allopregnanolone, modulate GABA receptors, exerting potent anxiolytic and sleep-promoting effects, thereby stabilizing mood and improving sleep architecture.

Perimenopause Progesterone Therapy

Meaning

Perimenopause Progesterone Therapy is the clinical administration of progesterone, typically bio-identical, to women experiencing the transition period leading up to menopause, which is characterized by fluctuating and often declining ovarian hormone production. This therapy is primarily used to mitigate symptoms associated with estrogen dominance and functional progesterone deficiency, such as irregular bleeding, sleep disturbances, anxiety, and mood volatility. It is a targeted intervention aimed at restoring hormonal equilibrium during a period of significant endocrine instability.
