In contrast, functional hypogonadism is caused hypogonadism conditions that suppress gonadotropin and T concentrations but that are potentially reversible with treatment of the underlying etiology. According to the guidelines, the patient should be evaluated at 3 to 6 months after treatment initiation and then annually to assess whether symptoms have responded to treatment and whether the patient is suffering from any adverse effects. References 1. Diagnosis Confirming a diagnosis of hypogonadism generally involves three components. In men whose total T is near the lower limit of normal or who have a condition that alters sex hormone—binding globulin, we recommend obtaining a free T concentration using either equilibrium dialysis or estimating it using an accurate formula.
