Defense Secretary Pete Hegseth has announced a new military testosterone screening program that will test service members aged 30 and older for testosterone deficiency as part of their annual health assessment. Troops under 30 will be able to request the screening voluntarily.
Under the program, if a deficiency is identified, it will be entirely up to the individual service member whether to pursue testosterone replacement therapy (TRT). Hegseth framed the initiative as being about restoring and optimizing troops’ natural capabilities and protecting their long-term health, rather than about performance enhancement.
Background: How the Military Testosterone Screening Plan Came About
The move follows a provision in the Fiscal Year 2025 defense authorization bill that required the Pentagon to brief Congress on its existing testing and treatment protocols for low testosterone. Special operations veterans have separately linked low testosterone to a range of physical and mental health issues sometimes referred to as “Operator Syndrome.” Testosterone levels in men typically decline by about one percent a year after the age of 30 or 40, a change generally regarded as a normal part of aging, though a deficiency can be associated with fatigue, reduced muscle strength and lower bone density.
Criticism of the Testosterone Screening Program
The announcement has drawn skepticism from some medical experts, who argue the rationale behind the directive is not strongly supported by scientific evidence and have warned of risks including overdiagnosis, cardiovascular problems and infertility linked to unnecessary treatment. One researcher who studies men’s health noted that clinically low testosterone affects only a small share of men, questioning whether the issue is widespread enough in the military to justify the program, and whether 30 is an appropriate age to begin screening. Some commentators have also linked the initiative to a broader online fitness trend promoting testosterone as a marker of male vitality.
Wider Context: Masculinity and Military Culture
The screening plan fits a broader emphasis under Hegseth on fitness and traditional notions of masculinity, including stricter physical fitness standards imposed across the services. It also comes soon after the Food and Drug Administration moved to widen access to testosterone replacement therapy, easing decades-old restrictions that limited its use largely to men with specific medical conditions affecting testosterone production.
Political Reaction
The announcement has also become a flashpoint in Washington. At least one Democratic lawmaker mocked the plan as excessive, suggesting Hegseth’s public focus on masculinity and physical appearance had gone too far. Supporters of the initiative, however, point to the department’s declared duty to protect the long-term health of service members, arguing that offering a simple, optional screening as part of an exam troops already undergo carries little downside. The Defense Department has so far declined to say whether a comparable hormone screening will be offered to female service members, or whether declining recommended treatment could carry any consequences.
What Happens Next With the Screening Rollout
Hegseth has not specified an exact start date for the rollout, and officials have not detailed how the screening will be standardized across the Army, Navy, Air Force, Marine Corps and other branches. With the policy debate likely to continue, both supporters and critics say further clarity from the Pentagon on eligibility, testing thresholds and follow-up care will determine whether the program is seen as a genuine health measure or, as some skeptics argue, a symbolic gesture tied to a broader cultural push around masculinity in the military.
