The U.S. Department of Defense has issued new clinical guidelines mandating hormone screenings for active-duty and reserve service members, effective immediately. The policy requires male troops aged 30 and older to undergo annual testosterone-deficiency screenings, while female service members of all ages will receive hormone-related assessments, including evaluations for conditions like Relative Energy Deficiency in Sports (RED-S) and perimenopause/menopause symptoms for those 35 and older.
The Defense Health Agency released the guidelines on Wednesday, outlining the scope and implementation of the screenings. Male service members under 30 may opt for voluntary annual testing. Female troops will be assessed for symptoms such as fatigue, musculoskeletal pain, or menstrual changes, with further evaluation for hormonal dysregulation. The policy also allows for modified training, duty restrictions, or limited-duty status based on the severity of diagnosed conditions.
Department of Defense officials stated the initiative aims to identify and treat suboptimal hormone levels to enhance warfighter performance and maximize force readiness. The guidelines emphasize testosterone as a critical biological marker influencing physical strength, bone density, aerobic fitness, mental health, and cardiovascular health. Service members reporting symptoms such as diminished endurance, muscle loss, or cognitive difficulties may undergo standardized diagnostic workups.
Defense Secretary Pete Hegseth previously highlighted the policy’s intent in a July announcement, framing it as a measure to restore natural capabilities rather than enhance performance artificially. Hegseth noted that testosterone replacement therapy, if recommended, remains optional for affected service members. The Pentagon’s announcement follows Hegseth’s social media video titled “The High-T Department of War,” where he described the initiative as protecting service members’ longevity and sustaining combat effectiveness.
The guidelines apply to all active-duty and reserve components, with screenings integrated into annual Periodic Health Assessments. Male troops answering affirmatively to questions about reduced performance, fatigue, or sexual health concerns will proceed to further medical evaluation. Female troops reporting symptoms such as fatigue or menstrual irregularities may be evaluated for underlying hormonal imbalances.
The policy reflects a broader military focus on proactive health management, aligning with prior initiatives to address mental health, nutrition, and physical conditioning. Officials emphasized that early detection and intervention could mitigate long-term health risks and maintain operational readiness across the force.
