What is the Origin of GnRH Analog Therapy?

The term combines the abbreviation for Gonadotropin-Releasing Hormone with analog, indicating a synthetic compound structurally similar to the native peptide. The discovery and subsequent synthesis of the GnRH decapeptide in the 1970s paved the way for creating modified versions with enhanced potency and stability, allowing for effective clinical manipulation of the hypothalamic-pituitary-gonadal (HPG) axis.

What is the Mechanism of GnRH Analog Therapy?

GnRH agonists, when administered continuously, initially cause a transient surge in LH and FSH, followed by a profound and sustained downregulation of pituitary GnRH receptors, leading to a chemical castration effect by suppressing gonadal hormone production. Conversely, GnRH antagonists immediately bind to and block the GnRH receptors, preventing the release of LH and FSH and achieving a rapid, reversible suppression of sex hormone levels. This precise control over the HPG axis allows clinicians to manage conditions driven by excessive or cyclical sex hormone exposure.

GnRH Analog Therapy

Meaning

GnRH Analog Therapy refers to the clinical use of synthetic compounds that mimic or block the action of Gonadotropin-Releasing Hormone (GnRH), the master regulator of the reproductive endocrine axis. These therapeutic agents, categorized as agonists or antagonists, are employed to strategically modulate the secretion of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) from the pituitary gland. They are widely used in treating hormone-sensitive conditions, including prostate cancer, endometriosis, uterine fibroids, and in controlled ovarian stimulation for fertility treatments.
