Secretary of War Pete Hegseth has announced a new health initiative that will implement mandatory annual testosterone screenings for active-duty U.S. service members aged 30 and older. The program, which Hegseth has dubbed the "High-T Department of War," is intended to maximize the biological readiness and long-term health of combat forces, according to a video posted on his official X account.
Hegseth described the policy as a "modern step" toward ensuring troops remain on the "leading edge of lethality." The initiative is reportedly a response to "operator syndrome," a complex set of physiological and psychological health issues, including endocrine disruption, chronic joint pain, traumatic brain injury (TBI), and depression, often experienced by special operations forces and long-serving combat veterans after prolonged deployments and chronic stress.
Under the new directive, testosterone level assessments will be integrated into the military's standard annual periodic health assessments. Service members over 30 will be required to undergo the screening, while those younger than 30 will have the option to request it voluntarily.
Testosterone deficiency affects approximately 5.6 percent of men aged 30 to 79 and can lead to fatigue, weight gain, muscle loss, and sexual dysfunction. Troops diagnosed with a deficiency will have the option to pursue testosterone replacement therapy, though Hegseth emphasized that any treatment would be voluntary. "This initiative is not about artificial enhancement," Hegseth stated in his video message. "It's about restoring and optimizing your natural capabilities, protecting your longevity, and ensuring you have the biological foundation required to sustain the fight."
This policy aligns with a broader administration focus on hormone health. The Secretary of War framed the screening program as a logical application of medical science, noting the natural decline of testosterone levels with age. He argued that while the Pentagon invests heavily in advanced weapons systems, the individual service member remains the military's most critical tactical asset.
The announcement is part of Hegseth's broader effort to reform the physical culture of the U.S. armed forces. Since taking office, he has advocated for rigorous physical fitness standards and has previously introduced initiatives to address obesity and standardize physical requirements across combat roles. Last September, Hegseth stated at an event in Quantico, Virginia, that he had no tolerance for overweight troops or "fat generals and admirals."
Department of War officials confirmed that the program will be conducted under the supervision of military medical professionals and is designed for early health marker monitoring. The test can be administered through bloodwork, urine, or saliva samples. "We owe our warriors the absolute best medical care in the world, and this program delivers on that obligation," Hegseth said, adding that the policy is intended to support service members both during their active-duty careers and after they transition to civilian life.
