What is the Origin of GnRH Analogues?

The term combines 'GnRH,' an acronym for Gonadotropin-Releasing Hormone, with 'analogues,' derived from the Greek analogos (proportionate, corresponding). These are synthetic molecules structurally similar to the native hormone. Their development marked a significant advancement in reproductive and endocrine medicine, allowing for precise pharmacological control over the hypothalamic-pituitary-gonadal axis.

What is the Mechanism of GnRH Analogues?

GnRH analogues function through two distinct mechanisms based on their administration pattern. When given continuously or in high doses (agonists), they initially stimulate but then cause persistent desensitization and down-regulation of GnRH receptors on the pituitary gland, leading to a profound suppression of LH and FSH release and subsequent sex hormone production. Conversely, when administered in a pulsatile fashion or when using antagonist versions, they can stimulate or immediately block the receptors, respectively, achieving specific therapeutic goals.

GnRH Analogues

Meaning

GnRH Analogues are synthetic compounds designed to mimic or antagonize the action of Gonadotropin-Releasing Hormone (GnRH), the hypothalamic peptide that regulates the pituitary-gonadal axis. These pharmacological agents are utilized in clinical endocrinology to either stimulate or suppress the production of sex hormones, depending on the dosing regimen. They are essential therapeutic tools for managing hormone-sensitive conditions such as endometriosis, uterine fibroids, prostate cancer, and precocious puberty.
