LHRH (luteinizing hormone-releasing hormone) is a decapeptide hormone which is synthesized in neurosecretory cells within the hypothalamus and released in a pulsatile fashion into the pituitary portal circulation. Since it controls the secretion of the gonadotropins LH (luteinizing hormone) and FSH (follicle-stimulating hormone) from the anterior pituitary gland, it is also designated as GnRH (gonadotropin-releasing hormone). Pulsatile secretion is essential for reproductive functions, sexual development, and differentiation. Prolonged non-pulsatile administration of LHRH results in a down-regulation of LH and FSH secretion from the anterior pituitary gland, followed by a suppression of gonadal steroid synthesis. This effect, which is shared by longer-acting GnRH agonists, is used for the treatment of hormone-dependent breast and prostate cancers but also for the treatment of endometriosis and precocious puberty. In reproductive medicine, continuous administration of LHRH agonists serves to prevent a premature LH surge prior to stimulation of ovulation. In this monograph Bachem presents its LHRH agonists and antagonists for endocrinological research and its generic APIs in this field.
