The U.S. Department of Defense has moved from proposing to mandating a new policy regarding testosterone testing for military personnel. Initially, the Department of Defense proposed monitoring testosterone levels to support readiness, with annual testing for service members over 30 and optional testing for those under 30. Defense Secretary Pete Hegseth emphasized the importance of hormone health for maintaining readiness. Following this proposal, the Pentagon issued immediate clinical guidelines making testosterone deficiency screening mandatory for active-duty and reserve service members aged 30 and older. While younger service members will only be tested upon request or if clinicians observe warning signs, the policy for women requires screening for fatigue and disrupted menstrual cycles rather than routine blood tests. The guidelines also include parameters for prescribing off-label testosterone to postmenopausal women. The Defense Health Agency stated the goal is to improve military readiness by managing hormonal and energy-availability issues. However, medical experts have raised concerns regarding the scientific basis of the mandate, warning that broad, routine testing could lead to unnecessary treatments and health complications such as infertility or blood clots. Some doctors have noted limited evidence that such screenings directly improve combat readiness. In response to the ongoing medical debate, the Food and Drug Administration is scheduled to hold an expert meeting in mid-September to discuss the medical use of testosterone. On September 2, 2026, the Pentagon temporarily rescinded the detailed clinical guidance published regarding these protocols to allow for updates. Although the specific document was removed from official websites, interim guidance remains in effect while the policy continues to face scrutiny from medical experts.
