U.S. Defense Secretary Pete Hegseth said the Pentagon will begin mandatory annual screenings for testosterone deficiency for service members [1].
The policy marks a significant shift in military health assessments by targeting hormonal levels as a key component of readiness. By focusing on testosterone, the Department of Defense aims to address physiological decline associated with aging in the force.
Under the new guidelines, the mandatory health assessments will apply to all service members aged 30 and older [1]. These screenings will occur on a yearly basis [1]. If a deficiency is identified during the screening, the military will offer hormone-replacement therapy as an optional treatment [1].
Hegseth said the initiative is designed to restore and optimize the health of soldiers rather than provide artificial performance enhancement. He said, "It's not about artificial enhancement. It's about restoring and optimizing you" [2].
While the screenings are mandatory, the medical intervention remains voluntary. Hegseth said, "If treatment is recommended, it’s entirely your choice to receive testosterone replacement therapy" [3].
The announcement has drawn scrutiny from some medical professionals regarding the claims of health optimization. Additionally, while the Secretary referred to "soldiers" [4], it remains unclear if the specific implementation of the plan will apply differently to women in the service [4].
The Department of Defense has not yet released the specific clinical thresholds that will define a "deficiency" for the purposes of these annual tests.
“"It's not about artificial enhancement. It's about restoring and optimizing you."”
This policy represents a move toward 'biomedical optimization' within the U.S. military. By institutionalizing testosterone screenings, the Pentagon is treating hormonal health as a metric of combat readiness. The optional nature of the therapy is intended to avoid accusations of forced medical enhancement, but the mandatory nature of the testing ensures the Department has a comprehensive data set on the endocrine health of its aging workforce.
