Pentagon issues mandatory testosterone screening for male troops age 30 and older

Thursday, September 3, 2026 · 2 sources

The Pentagon issued clinical guidelines requiring testosterone blood tests for active-duty and reserve men ages 30 and older. Defense Secretary Pete Hegseth had announced the readiness screening program in July; treatment for low levels would be voluntary if clinically appropriate.

The Pentagon on Wednesday issued clinical guidelines for mandatory testosterone deficiency screening of active-duty and reserve service members ages 30 and older, Fox News reported.

Defense Secretary Pete Hegseth announced the program in July, saying troops need the right hormone levels to operate at their best and to stay healthy after they leave uniform. Under the new guidance, which took effect immediately, men 30 and older will get mandatory testosterone blood tests. Younger men will be tested only if they ask or if clinicians see warning signs.

Men with low levels may get further evaluation and, if clinically appropriate, may be offered voluntary hormone replacement therapy. Testosterone use for non-medical performance enhancement without a prescription remains prohibited. Women will not face routine testosterone blood tests, but the guidance covers screening for fatigue and menstrual disruption tied to low energy availability, and sets rules for limited off-label testosterone use in some postmenopausal cases.

Some endocrinologists told reporters there is limited evidence that universal screening improves readiness and warned against unnecessary treatment. The Food and Drug Administration plans a meeting later this month on medical testosterone use. Reuters contributed to the Fox News report.

The 50+ takeaway: Military screening is mandatory for men 30 and up; therapy remains voluntary and clinical. Non-medical testosterone use stays banned. Civilians should not self-dose based on this policy.
