Elevated luteinizing hormone despite normal testosterone levels in older men-natural history, risk factors and clinical features
Objective: Elevated luteinizing hormone (LH) with normal testosterone (T) suggests compensated dysregulation of the gonadal axis. We describe the natural history, risk factors and clinical parameters associated with the development of high LH (HLH, LH >9.4 U/L) in ageing men with normal T (T ≥ 10.5 nmol/L). Design, Patients and Measurements: We conducted a 4.3-year prospective observational study
