US Military Will Check Troops' Testosterone Levels Each Year

Defense Secretary Pete Hegseth said July 15, 2026, that the military will check troops' testosterone — a hormone affecting energy, muscle, and health — once a year during regular checkups. Troops 30 and older must take part; younger ones can choose. Treatment to boost low testosterone stays optional. Hegseth called it preserving troops' "biological foundation," not artificial enhancement.
