Defense Secretary Pete Hegseth said the Pentagon will now require annual testosterone deficiency screenings for active-duty service members age 30 and older [1].

The policy shift targets a specific age demographic within the military to monitor hormonal health. By mandating these tests, the Department of Defense aims to identify deficiencies that could impact the physical and mental readiness of personnel in the field.

Hegseth said the goal of the requirement is "ensuring you have the right testosterone levels to operate at your absolute best" [2]. The initiative focuses on maintaining high operational standards by addressing potential health gaps that may emerge as service members age.

Under the new guidelines, the screenings will occur on a yearly basis [1]. This mandate applies specifically to those who have reached the age of 30 and remain on active duty [1]. The Pentagon has not yet released specific details regarding the clinical protocols for treatment if a deficiency is discovered during these screenings.

The move represents a shift in how the U.S. military approaches preventative health and endocrine wellness. By integrating these tests into the annual medical requirements, the department treats testosterone levels as a key metric of combat readiness, similar to fitness tests or psychological evaluations.

Defense officials have not specified if these tests will be mandatory for all branches of the military or if certain specialized units will have different requirements. The implementation timeline for the first round of screenings remains unannounced.

The Pentagon will require annual testosterone deficiency screenings for active‑duty service members age 30 and older.

This policy indicates a broader effort by the Department of Defense to optimize human performance through medical intervention. By mandating endocrine screenings, the Pentagon is signaling that hormonal balance is now viewed as a critical component of military readiness and operational efficiency for aging personnel.
