Testosterone Screening Thresholds in Active-Duty US Male Service Members.

US Army-wide prevalence of healthy active-duty men aged 19 to 39 years with testosterone levels below the normal lower limit is estimated in this study.

• Why it matters: Understanding testosterone levels in young, healthy male service members is important for assessing potential health issues and guiding clinical decisions in military populations.
• What they did: The study used an estimation approach to determine the prevalence of testosterone concentrations below the lower normal limit among active-duty men aged 19 to 39 years across the US Army.
• The result: Findings provide a baseline for testosterone screening thresholds in this population, which may inform future health assessments and policy development.
