U.S. Defense Secretary Pete Hegseth announced that service members aged 30 and older must now undergo mandatory annual testosterone screenings [1].
This policy shift integrates hormone monitoring into the standard health readiness cycle. By identifying low testosterone levels early, the Department of Defense aims to maintain the physical and mental readiness of personnel as they age, a factor critical to operational effectiveness in high-stress environments.
The screenings will be added to the routine annual physical that military members already undergo [2]. Hegseth said the goal is to ensure service members have the right testosterone levels to operate at their full capacity [1]. He said the addition to the medical checklist is routine [3].
Under the new directive, the age threshold for these tests is 30 years old [1]. The frequency of the testing will be annual [2]. If the screenings reveal deficiencies, the military intends to provide referrals for hormone therapy to address the imbalance [1].
There have been varying reports regarding the exact scope of the rollout. Some reports indicate the order applies to all troops over 30 [3], while others suggest the military will begin by testing some service members [2]. Hegseth said the check would be added to an existing annual physical for military members [2].
This move marks a specific focus on endocrine health as a component of military readiness. The Department of Defense is prioritizing biological markers that influence strength, cognitive function, and recovery times, all of which are impacted by testosterone levels in men over 30 [1].
“Ensuring you have the right testosterone levels to operate at …”
This policy signals a shift toward 'precision readiness,' where the military treats hormonal balance as a performance metric similar to physical fitness scores. By institutionalizing these tests, the Department of Defense is acknowledging the biological impact of aging on combat effectiveness and creating a standardized pipeline for hormone replacement therapy within the ranks.
