WASHINGTON — United States Defense Secretary Pete Hegseth announced last month a new initiative dubbed the "High-T Department of War," which mandates testosterone deficiency screening for military personnel aged 30 and above. Those identified with low testosterone levels would be eligible for optional replacement therapy.

Hegseth stated in a video announcement, “I'm authorising a new screening programme for testosterone deficiency for our service members, ensuring you have the right testosterone levels to perform at your absolute best.” He emphasized that the program is "not about artificial enhancement" but about "restoring and optimising your natural capabilities, protecting your longevity, ensuring you have the biological foundation required to sustain the fight."

Testosterone, the primary male sex hormone, plays a role in regulating muscle mass, bone density, and other bodily functions. However, medical experts have raised concerns about the program's potential benefits and risks. Adrian Dobs, professor of medicine and oncology at the Johns Hopkins University School of Medicine, noted, “There’s very little change at what we would call replacement doses.”

Clinical psychologist Chris Frueh, who has researched testosterone deficiency, believes that related health problems are often under-reported due to stigma. He hopes the focus on testosterone will be part of a broader approach addressing hormones, sleep, diet, brain health, and pain management. This view was echoed by a professor of psychology at the University of Hawaii-Hilo, who said, “My hope, my optimistic belief, is that focusing on testosterone is part of a much larger picture and approach that will focus not just on testosterone, but hormones more broadly, sleep, diet, brain health, pain management etc.”

Experts remain skeptical about whether the screening will enhance combat performance and warn it could expose troops to unnecessary health risks.
