What is the Meaning of GnRH?

GnRH, or Gonadotropin-Releasing Hormone, is a critical hypothalamic neuropeptide that initiates reproductive function by signaling the pituitary gland. This decapeptide controls the pulsatile release of both Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), thereby regulating gonadal steroidogenesis and gamete production. Its pulsatile nature is paramount for maintaining reproductive health.

What is the Origin of GnRH?

The name reflects its function: it releases gonadotropins, which are tropic hormones acting on the gonads. GnRH is synthesized in the hypothalamus and released into the portal hypophyseal circulation, linking the nervous and endocrine systems.

What is the Mechanism of GnRH?

GnRH binds to specific G-protein coupled receptors on anterior pituitary gonadotroph cells, triggering intracellular signaling cascades involving calcium influx and PKC activation. The frequency and amplitude of GnRH pulses dictate the specific ratio of LH to FSH secreted, which in turn governs the menstrual cycle or spermatogenesis. Continuous, non-pulsatile exposure to GnRH leads to receptor downregulation and functional suppression of the HPG axis.
