“We owe our warriors the absolute best medical care in the world, and this program delivers on that obligation,” Defense Secretary Pete Hegseth said in a video posted to X. The announcement introduces a mandatory testosterone screening initiative aimed at ensuring every soldier with a duty cycle of 30 years or more has optimal hormone levels.
“The new protocol will enable the Department to establish a comprehensive baseline and offer targeted testosterone therapy, ensuring that it sustains a healthy, capable, and decisively dominant fighting force,” Pentagon spokesperson Sean Parnell explained. “You have the right testosterone levels to operate at your absolute best.”
Under the new rules, service members over 30 will receive annual tests, while younger troops can request a screening if they suspect low levels. Identified individuals will be offered voluntary replacement therapy administered under medical guidance. The program explicitly differentiates itself from illicit performance enhancement, with Hegseth stressing, “Taking testosterone for non‑medical reasons, like artificial muscle enhancement without a doctor’s prescription, is strictly prohibited in the military. This program is not about artificial enhancement.
Dr Mohit Khera, a Baylor College of Medicine professor who led an FDA panel on testosterone utilization, highlighted the health benefits of replacement therapy: “Increased muscle mass, decreased fat deposition, reduced risk for depression, and improved bone density.” He cautioned that therapies should target symptomatic individuals and warned of fertility, cardiovascular, and endocrine side effects.
The move comes as U.S. Health Secretary Robert F Kennedy Jr and other Trump administration officials push to lower barriers for prescribing testosterone, citing a national ‘fertility crisis.’ The FDA recently sought to remove safety language from testosterone product labels and relax prescribing limits. Hegseth’s announcement thus dovetails with broader policy shifts toward therapeutic hormone use in the armed forces.
