Metabolomics During Testosterone Therapy

One promising but understudied area in the field of testosterone (T) therapy is its effect on metabolism and the development of type II diabetes. Metabolomics is a powerful research tool that can detect very early signs of metabolic derangement that may lead to metabolic disease. In this observational study, investigators aim to apply metabolomics in order to better understand how T therapy influences metabolism. In a clinical population of outpatient men with T deficiency investigators will perform comprehensive clinical evaluations and also obtain blood for metabolomics. This will be done once prior to T therapy and again after 4-6 months of T therapy. Investigators hypothesize that they can detect metabolic derangements in men with T deficiency and that these derangements will improve with T therapy.
