title: Evaluation for Testosterone Deficiency.
abstract: There has been a recent increase in the number of Operators presenting to clinics for evaluation of possible low testosterone. In response, USASOC recently released an Androgen Deficiency Clinical Practice Guideline (CPG) to help guide providers through the initial evaluation and treatment of patients. The diagnosis of hypogonadism is based on consistent signs and symptoms of androgen deficiency and unequivocally low serum testosterone (below 300 ng/dL). Testosterone levels can change for a variety of reasons and an adequate evaluation requires multiple laboratory tests over a period of time. If a diagnosis of hypogonadism is confirmed, differentiating between primary and secondary hypogonadism can help guide further care. Testosterone replacement therapy options are available, but careful monitoring for side-effects is required. Controversy still exists surrounding the safety of testosterone replacement therapy, and referral to endocrinology should strongly be considered before initiating treatment.
