US Military to Require Testosterone Screening for Personnel Aged 30 and Older

On July 17, 2026, Defense Secretary Pete Hegseth announced that the US military will require all active duty and reserve personnel aged 30 and older to undergo mandatory screening for testosterone deficiency during their yearly health assessments. Personnel under 30 may also request screening. In a video shared on social media, Hegseth stated that the initiative aims to optimize performance, resilience, and long-term health, clarifying that it is not intended for artificial enhancement and that members can decline treatment. The effectiveness of testosterone screening and treatment in enhancing military personnel's longevity and capabilities has raised questions among medical professionals.
