Moenter SM. Leap of Faith: Does Serum Luteinizing Hormone Always Accurately Reflect Central Reproductive Neuroendocrine Activity? Neuroendocrinology. http://www.karger.com/Article/Abstract/438790
Function of the central aspects of the hypothalamo-pituitary-gonadal axis has been assessed in a number of ways including direct measurements of hypothalamic output and indirect measures using gonadotropin release from the pituitary as a bioassay for reproductive neuroendocrine activity.
Here, methods for monitoring these various parameters are briefly reviewed and then examples presented of both concordance and discrepancy between central and peripheral measurements, with a focus on situations in which elevated GnRH neurosecretion is not reflected accurately by pituitary luteinizing hormone release.
Implications for interpretation of gonadotropin data are discussed.
