US Military to Screen Troops' Testosterone Annually Under New Hegseth Policy

Defense Secretary Pete Hegseth announced on July 15, 2026, that the US military will add annual testosterone screening to its existing periodic health assessment. Service members 30 and older must participate; those under 30 may opt in. Treatment, including testosterone replacement therapy, remains voluntary. Hegseth framed the initiative as sustaining troops' "biological foundation," not artificial enhancement.
