Pete Hegseth orders annual testosterone screening for U.S. troops 30 and older

U.S. Defense Secretary Pete Hegseth announced on July 15 that all active‑duty and reserve service members aged 30 and older will undergo annual testosterone testing, a policy that will affect roughly two million troops. The screening will be part of routine health assessments; personnel under 30 can request the test voluntarily. Any hormone‑replacement therapy offered for diagnosed deficiency will also be voluntary.

The Pentagon has not provided a cost estimate or evidence that the program improves combat readiness. Medical experts have questioned the scientific basis, with endocrinologist Dr. Richard Auchus stating, "I can't think of a medical one, so it must be a policy one." Senators Richard Blumenthal, Mazie Hirono, Gary Peters, Elizabeth Warren and Ruben Gallego wrote that the department "has provided no evidence that this sweeping new policy will improve force readiness or health."

The mandate sparked broader criticism, including a controversial joke by Fox News host Jesse Watters, who warned women on bases that "the guys are going to be wild animals" if the testosterone injections are used. Health professionals warned of potential over‑diagnosis, side‑effects such as reduced natural hormone production and risks to both male and female service members. The policy is under scrutiny by Congress and the medical community as it proceeds toward implementation by the August 15 deadline.
