Prediction of Testosterone Response to Human Chorionic Gonadotrophin in idiopathic Hypogonadotropic Hypogonadism Patients

We conclude that basal inhibin B predicts the testosterone response to hCG in IHH patients and therefore gives reliable information about Leydig cell reserve. Furthermore, inhibin B levels show negative correlation with luteinizing hormone (LH) in control patients and positive correlation with FSH and LH in IHH patients. LH may effect inhibin B secretion. Further studies are necessary to define the physiology of inhibin B in human males.
