WASHINGTON: Defense Secretary Pete Hegseth announced Wednesday that he is rolling out a new screening program for “testosterone deficiency” among troops, calling it necessary to allow them to operate at their “absolute best.”

The screenings will be conducted annually as part of service members’ required medical screenings for those 30 and older, he said. Troops under 30 can volunteer to be tested. In a video on social media, Hegseth said receiving testosterone replacement therapy would be voluntary.

In the video, Hegseth simply refers to troops, though it appears he is talking about only testing men in uniform for hormone irregularities.

The move comes as other Trump administration officials have begun to advocate for men to have easier access to testosterone replacement therapies, but the messaging from Hegseth and others blends known science on the hormone with broader, and less substantiated, claims.

Testosterone use in the military has previously come under scrutiny
