Gonadorelin is also known as “gonadotropin releasing hormone,” or “GnRH.” It is bioidentical to (exactly the same as) the natural neuropeptide produced by the hypothalamus, a part of the brain. In a normal and healthy young male, gonadorelin is always being produced, but is only released in a pulsatile manner from the hypothalamus about every two hours. The neuropeptide is delivered directly to the anterior pituitary gland, which responds to the stimulation by releasing in its own pulsatile fashion a bolus of luteinizing hormone (LH), follicle stimulating hormone (FSH), and even small amounts of human chorionic gonadotropin (HCG). These hormones travel from the anterior pituitary to the testicles to stimulate them to produce testosterone, estrogen, and sperm.
