U.S. Defense Secretary Pete Hegseth announced on July 15, 2026, that testosterone screening will be mandatory for American military personnel aged 30 and over. The Pentagon will also offer testosterone treatment to troops who require it, the Financial Times reported.
Hegseth framed the initiative around building a more "manly" military, the BBC reported. The announcement came as concerns about virility and declining sperm counts have gained attention on the American right, according to the Financial Times.
