What is the Meaning of Estrogen Suppression?

Estrogen suppression is the clinical strategy or physiological state characterized by the deliberate reduction of circulating estrogen concentrations to therapeutic levels. This is often implemented in the management of hormone-sensitive conditions, such as certain cancers, or as a consequence of physiological states like low energy availability. The degree and method of suppression must be carefully managed, as excessive or prolonged reduction can negatively impact bone mineral density, cardiovascular health, and cognitive function.

What is the Origin of Estrogen Suppression?

The practice of estrogen suppression has its origins in oncology, specifically the understanding that certain breast and endometrial cancers are driven by estrogen's proliferative signaling. This led to the development of pharmaceutical agents designed to interrupt the estrogen biosynthesis pathway or block its receptor action. The therapeutic goal is to mitigate the stimulatory effects of the hormone on target tissues.

What is the Mechanism of Estrogen Suppression?

Pharmacological suppression is most commonly achieved through the use of aromatase inhibitors, which block the enzyme responsible for converting androgens into estrogens in peripheral tissues. Alternatively, Gonadotropin-Releasing Hormone (GnRH) agonists or antagonists can be employed to reduce the pulsatile release of pituitary gonadotropins, thereby decreasing ovarian and adrenal estrogen production. Both mechanisms aim to limit the amount of bioavailable hormone reaching estrogen receptors.
