U.S. Secretary of Defense Pete Hegseth said that military personnel over 30 will undergo annual testosterone tests as part of periodic medical reviews [1].
The policy aims to maintain the physical and mental readiness of the troops by identifying hormone deficiencies. By integrating these screenings into standard health checks, the Department of Defense seeks to ensure that personnel meet the rigorous demands of military service through medical intervention when necessary.
Under the new guidelines, soldiers who are 30 years of age or older [1] will be required to undergo these screenings on an annual basis [1]. The initiative is designed to provide a systemic way to monitor the biological health of the force and offer clinical solutions to those exhibiting low levels of the hormone.
For personnel found to have a deficit, the department will offer hormone replacement therapy. Hegseth said, "Se recomendarán terapias con hormonas en caso de que los soldados tengan bajos niveles de testosterona" [2].
The program is applicable to all U.S. military personnel regardless of their specific branch, or current assignment. The Department of Defense in Washington, D.C., said that the goal is to guarantee that troops remain physically and mentally prepared for their duties [1].
This medical shift reflects a broader focus on the long-term wellness of aging service members. By identifying endocrine issues early, the military intends to reduce the risk of fatigue and mental health decline associated with low testosterone levels in older personnel.
“Military personnel over 30 will undergo annual testosterone tests.”
This initiative signals a shift toward proactive endocrine management within the U.S. military to sustain combat readiness in an aging force. By institutionalizing hormone replacement therapy, the Department of Defense is treating hormonal health as a critical component of operational readiness, potentially setting a precedent for how other government health agencies manage age-related biological decline.
