Evaluating incidence, prevalence, and treatment trends in adult men with hypogonadism in the United States.

No extensive studies have investigated current diagnosis and treatment trends of hypogonadism (HG) in adult men in the United States. Using a comprehensive commercial insurance database, we surveyed current trends in incidence, prevalence, and treatment of hypogonadism in the United States. We analyzed insurance claims data from 2008-2017 using the IBM MarketScan™ Commercial Claims and Encounters database for men ≥18. Overall, we estimated annual incidence at 16.1 cases per 100,000 person-years, with the highest incidence seen among men 35-44 years at 21.5 cases per 100,000 person-years (IRR 1.83; 95% CI 1.63, 2.06, p < 0.001) and among those living in the Southern United States at 22.6 cases per 100,000 person-years (IRR 1.96; 95% CI 1.76, 2.18, p < 0.001). The prevalence of HG across the study period increased from 0.78% to 5.4%, while treatment rates decreased from 32.9% to 20.8%. These study findings provide a large-scale view of current diagnosis rates and treatment of hypogonadism in adult men in the United States. Despite the increase in prevalence of disease, there is an observed decline in treatment rates after diagnosis. Further investigations are needed to identify factors driving the observed decline in healthcare utilization among men with hypogonadism.
