The U.S. military will begin measuring the testosterone levels of its soldiers, according to an announcement made Wednesday [1].
The initiative aims to identify hormonal deficits and provide treatments to enhance the physical and mental performance of personnel in combat environments. By monitoring these levels, the military intends to optimize the natural capacities of its force to ensure maximum readiness.
Defense Secretary Pete Hegseth said the policy was announced July 15 [1]. The program specifically targets soldiers aged 30 and older [2]. Personnel meeting this age requirement will be subject to testing to determine if they have a testosterone deficiency.
If a deficit is identified, the military plans to offer hormonal treatments to the affected soldiers [3]. This approach is designed to help service members maintain the strength, and endurance necessary for active duty. The goal is to ensure that soldiers can better withstand the rigors of combat [4].
While the program focuses on performance optimization, the move introduces a new layer of medical screening for adult personnel. The administration said the effort is a way to recover and maximize the natural biological capabilities of the troops [1].
Some reports have suggested the Department of Defense was renamed the "Ministry of War" by Donald Trump, though other sources do not confirm this change [1]. The primary focus of the current rollout remains the implementation of the testing protocols for the specified age group [2].

This policy represents a shift toward biological optimization within the U.S. military, treating hormonal balance as a component of combat readiness. By focusing on soldiers 30 and older, the Department of Defense is addressing age-related physiological decline, potentially normalizing the use of hormone replacement therapy to maintain a high-performance force.
