Overview of Gonadorelin (GnRH)
Mimics endogenous GnRH signaling to stimulate pulsatile release of LH and FSH, maintaining gonadal function and fertility.
Binds to GnRH receptors on pituitary gonadotroph cells, triggering signaling cascades for hormone release.
Stimulates pulsatile release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), maintaining gonadal function.
When used alongside TRT, maintains intratesticular testosterone production, preserving fertility and testicular size.
Pulsatile administration maintains stimulatory effect, as continuous exposure causes receptor desensitization.
Used to stimulate ovulation in women and spermatogenesis in men with hypothalamic hypogonadism, with fertility applications
