U.S. Defense Secretary Proposes Testosterone Screening for Service Members, Drawing Congressional Scrutiny

2026-07-21

The BareStory

U.S. Defense Secretary Pete Hegseth has issued a directive to begin testing the testosterone levels of military service members aged 30 and older during their annual physical exams. Under the plan, which requires an implementation strategy by August 15, troops under the age of 30 can voluntarily opt into the screenings, and any subsequent hormone replacement therapy would also remain voluntary. Hegseth stated during a Pentagon briefing that the initiative aims to help service members operate at their highest level.

The proposal has drawn opposition from several Democratic senators, including Richard Blumenthal, Mazie Hirono, Gary Peters, Elizabeth Warren, and Ruben Gallego. In a letter to Hegseth, the lawmakers questioned the scientific basis, financial costs, and potential consequences of the policy. The senators claimed the Pentagon has not provided evidence that the screenings will improve force health or readiness, and raised concerns regarding how the policy would affect female service members and whether those with low testosterone would face administrative consequences.

Medical professionals have also urged caution regarding the military's plan. Experts noted that clinical testosterone deficiency affects only about two percent of men, and temporary factors such as stress, poor nutrition, and lack of sleep can temporarily lower hormone levels. While testosterone replacement therapy can improve bone density and muscle mass for those with diagnosed clinical deficiencies, physicians warned that the treatment suppresses natural hormone production, which could lead to dependency. Additionally, medical experts pointed to potential risks of the therapy, including blood clots, fluid retention, and cardiovascular complications.

How it may affect me

As a U.S. reader:

• Because the proposed testosterone screening and hormone therapy program applies exclusively to active-duty military service members, no significant direct impact is expected for civilian members of the general public.
