Defense Secretary Pete Hegseth has announced a mandatory annual testosterone screening program for U.S. service members over 30, turning a wellness-world fixation into military policy.
Hegseth described the plan in a video posted to X, where the accompanying text called it “The High-T Department of War.” In the video, Hegseth said the military has a duty to protect service members’ performance, resilience and long-term health, then laid out the new testing program.
Under the policy Hegseth announced, troops older than 30 will be screened each year for testosterone deficiency. Service members younger than 30 will be able to get the test voluntarily. If a deficiency is identified, Hegseth said troops may choose testosterone replacement therapy, known as TRT, but will not be required to take it.
The New York Times reported that the screening program will include women. That detail matters because testosterone is often discussed in public as shorthand for male strength or aggression, which is a sloppy way to talk about an actual hormone measured in actual bodies. The program Hegseth described is framed around detecting deficiency, then offering replacement therapy only to those who opt in.
Hegseth insisted in the video that the program is aimed at restoration rather than enhancement. He said the initiative is “not about artificial enhancement” and described it as a way to restore and optimize natural capabilities, protect longevity and provide what he called the biological foundation to “sustain the fight.”
The mechanics, at least as publicly described, are straightforward: the military tests eligible service members for low testosterone, identifies those who meet its deficiency criteria, and offers TRT as an elective treatment. Hegseth did not, in the available remarks, specify the medical thresholds, implementation timeline, testing protocol, or how commanders and military clinicians will handle privacy and readiness issues tied to hormone screening.
That leaves the important parts in the paperwork nobody has seen yet. A screening mandate is not the same thing as mandatory treatment, and Hegseth said therapy would be optional. But the military is also not a normal workplace. Once a biomarker becomes part of an annual readiness-adjacent process, the difference between medical care and performance management can get thin fast.
For now, the confirmed policy is narrower than the branding around it: annual testosterone deficiency checks for service members over 30, voluntary testing for younger troops, and optional TRT after a deficiency finding. The rest depends on the rules the Defense Department writes after the X video stops doing policy work.
