What is the Origin of Menopausal Hormonal Therapy?

The practice originated in the 1940s with the introduction of estrogen-only treatments, becoming widespread as Hormone Replacement Therapy (HRT). Following key clinical trials and subsequent re-analysis, the nomenclature shifted to Menopausal Hormonal Therapy (MHT) to reflect a more precise understanding of its purpose and the necessary inclusion of a progestogen for women with a uterus. It remains a cornerstone of postmenopausal clinical care for symptom management.

What is the Mechanism of Menopausal Hormonal Therapy?

The administered estrogen binds to estrogen receptors (ERα and ERβ) throughout the body, including the hypothalamus, bone, cardiovascular tissue, and brain. This binding reactivates the signaling pathways that were suppressed by ovarian failure, alleviating hot flashes by stabilizing the hypothalamic thermoregulatory center. Furthermore, it supports bone density by inhibiting osteoclast activity and promotes urogenital tissue health by maintaining blood flow and collagen.

Menopausal Hormonal Therapy

Meaning

This clinical intervention involves the administration of exogenous hormones, primarily estrogen and often a progestogen, to alleviate the vasomotor, genitourinary, and systemic symptoms associated with the decline of ovarian function during and after menopause. The therapy aims to restore a more youthful hormonal milieu to mitigate the health risks and quality-of-life deficits of estrogen deficiency. It requires careful, individualized risk-benefit assessment by a qualified clinician.
