The U.S. Department of Defense will begin measuring the testosterone levels of soldiers to identify deficiencies and provide hormonal treatment [1, 2].
This initiative represents a shift in military health management by treating hormonal balance as a key component of combat readiness. By identifying deficits, the Pentagon aims to ensure that personnel maintain the physical capabilities required for high-stress operational environments.
Secretary of Defense Pete Hegseth said the military will measure the testosterone levels of recruits to identify potential deficits and offer hormonal treatment [1]. The program is designed to optimize the physical capacities of the force and ensure soldiers possess natural hormonal levels to preserve their long-term health [2, 4].
Implementation details vary across different service stages. Some reports indicate that the testing will be integrated into the recruitment process for new arrivals [1]. Other directives state that military members aged 30 and older will be required to undergo a testosterone test every year [3].
A Pentagon spokesperson said the program is not about artificially enhancing performance. The spokesperson said the goal is to recover and optimize natural capacities, preserve longevity, and ensure soldiers have the best possible state of health [4].
The policy focuses on the intersection of endocrine health and military efficiency. By addressing hormonal deficits, the Department of Defense intends to maintain a more resilient workforce capable of meeting the physical demands of service over a career spanning several decades [2, 3].
“The U.S. Department of Defense will begin measuring the testosterone levels of soldiers to identify deficiencies.”
This policy signals a move toward 'precision health' within the U.S. military, where biological markers are used to proactively manage soldier performance. By institutionalizing hormone replacement therapy (HRT) for those with deficits, the Pentagon is treating endocrine health as a strategic asset, potentially extending the effective operational lifespan of older service members.
