Reference Ranges Well-established reference ranges constitute the essential basis for identifying whether the circulating levels of a particular analyte, testosterone in this case, are normal or low. The results of ongoing and new systematic reviews will be included in the update of the Male Hypogonadism Guidelines.

All patients had PSA and digital rectal exams every three months and biopsies annually. Some of the cancers were detected during the treatment phase, while others were detected during post-study follow-up. The use of a PDE5I may also increase serum testosterone levels [ ]. J Bone Miner Res. Taylor et al. Testosterone deficiency is also associated with a failure of PDE5Is therapy [ 73 ].

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.
