Kallmann syndrome is caused by too little Gonadotropin Releasing Hormone (GnRH) from the hypothalamus gland. GnRH from the hypothalamus is supposed to stimulate the pituitary gland to release (LH) and (FSH); which in turn act on the sex organs and gonads. It is the hypothalamus gland that is defective in Kallman syndrome, not the pituitary gland.
