US Military Begins Mandatory Testosterone Testing For Service Members

The U.S. military is expanding routine health checks to include hormone-related testing, with new Pentagon rules requiring testosterone screening for a large portion of the force. The requirements apply to both active-duty personnel and reservists and took effect immediately, according to CBC.

The biggest change affects men beginning at age 30. They will now have testosterone levels checked through bloodwork as part of the military’s broader effort to identify health conditions that could interfere with physical performance, energy or readiness. Younger men will not automatically receive the same testing, although doctors can order it when symptoms raise concerns or a service member asks to be evaluated.

Female service members will be assessed under a separate protocol rather than receiving universal testosterone tests. Medical providers will look for symptoms such as persistent fatigue or changes in menstrual cycles that could signal inadequate energy intake, hormonal disruption or related health problems.

CBC writes that the Pentagon’s framework also gives military physicians direction on what to do when potential problems are discovered. That includes further evaluation and possible treatment rather than simply measuring hormone levels and leaving the results without follow-up.

Testosterone treatment for women is addressed as well, although in much narrower circumstances. The guidance allows doctors to consider off-label testosterone for certain postmenopausal women experiencing abnormally low sexual desire rather than recommending the hormone broadly.

The initiative follows a push by Secretary of War Pete Hegseth, who announced plans for expanded testosterone testing in July and has spoken favorably about the hormone. Pentagon officials are framing the program as another tool for maintaining a healthier and more capable fighting force.

Not everyone in the medical community is convinced. Some doctors have questioned whether routinely testing large numbers of otherwise healthy troops will produce meaningful improvements in military performance. They have also warned that finding borderline or naturally fluctuating hormone levels could encourage treatment that provides little benefit while carrying potential side effects.

The debate is unfolding as federal regulators separately examine testosterone therapy more broadly. The Food and Drug Administration is scheduled to bring together medical experts in mid-September to discuss the appropriate use of testosterone and the evidence surrounding its treatment applications.
