What is the Origin of Progesterone Support Strategy?

The term is rooted in reproductive endocrinology, with 'progesterone' deriving from its role as the 'pro-gestational' hormone, essential for maintaining pregnancy. The development of a 'support strategy' evolved from the clinical need to balance the proliferative effects of estrogen and leverage progesterone's unique anxiolytic and neuroprotective properties. Its clinical application expanded significantly with the realization of its role in non-reproductive tissues, including the brain and bone.

What is the Mechanism of Progesterone Support Strategy?

Progesterone exerts its effects by binding to specific nuclear progesterone receptors (PRs) in target tissues, where it modulates gene transcription. In the uterus, it induces secretory changes and counteracts estrogen-driven proliferation. Centrally, its neurosteroid metabolite, allopregnanolone, acts as a positive allosteric modulator of GABA-A receptors, leading to anxiolytic and sedative effects. A successful strategy ensures consistent receptor saturation in key tissues without causing unwanted side effects.

Progesterone Support Strategy

Meaning

A comprehensive clinical plan for administering or enhancing the endogenous production of the steroid hormone progesterone to achieve specific therapeutic endpoints, particularly related to reproductive health, neuroprotection, and hormonal balance. The strategy involves precise dosing and timing, often in conjunction with estrogen, to mimic physiological cycles and maximize the hormone’s beneficial effects on the endometrium, bone density, and central nervous system. This is a critical component of peri- and post-menopausal hormone therapy.
