Defense Secretary Pete Hegseth announced Wednesday that the Pentagon will begin requiring annual testosterone deficiency screenings for active-duty service members age 30 and older, saying the move is designed to improve military readiness and support long-term health.

The new policy, unveiled in a video posted to X, will make testosterone testing a standard part of the military’s existing annual periodic health assessments for troops over 30. Service members younger than 30 will have the option to receive the screening voluntarily.

“I’m authorizing a new screening program for testosterone deficiency for our service members, ensuring you have the right testosterone levels to operate at your absolute best,” Hegseth said in the video.
