Is testosterone testing mandatory in the U.S. military?

As announced on July 15, 2026, annual testosterone screening will be mandatory for active-duty service members age 30 and older, added to the yearly Periodic Health Assessment (PHA). Members under 30 can request the test voluntarily. Any treatment that follows, including testosterone replacement therapy (TRT), is voluntary — not required.

Is TRT (testosterone replacement therapy) mandatory under the new policy?

No. The screening is mandatory for eligible troops, but treatment such as TRT is explicitly voluntary. A low screening result does not obligate you to start any therapy.

Is a single testosterone number below 300 ng/dL a diagnosis of low testosterone?

No. Diagnosing hypogonadism requires persistent symptoms, low levels confirmed on repeat morning testing, and identifying a cause. A single number — especially from a non-morning draw — is a reason to talk with a clinician, not a diagnosis.

Why does the time of a testosterone blood draw matter?

Testosterone follows a daily rhythm and is highest in the early morning, so guidelines specify a fasting draw around 8-10 a.m. Afternoon values can read falsely low and are typically repeated in the morning before any conclusion.

2026 Screening Policy · Plain Reading

Military testosterone testing Now mandatory for troops 30 and older. Here's what your number means — and what the policy actually requires.

Q: Who ordered military testosterone screening and when does it start?

Defense Secretary Pete Hegseth announced the policy on July 15, 2026. Governing policy (DoD Instruction 6200.06, the PHA Program) is directed to be updated by August 15, 2026. The Department has not publicly stated an exact start date, cost, or phase-in schedule across the services.

The bottom line

Is testing mandatory?

Yes — for active-duty members 30 and older. Annual testosterone screening is being added to the Periodic Health Assessment (PHA) they already complete each year. Under 30, you can opt in voluntarily.

Treatment is not mandatory. If screening finds low testosterone, any therapy that follows — including TRT — is explicitly voluntary. A low result does not, by itself, mean you must start treatment.

Policy brief

The 2026 screening order

Defense Secretary Pete Hegseth announced the change on July 15, 2026, framing it as a readiness measure. The governing instruction — DoD Instruction 6200.06 (PHA Program) — is directed to be updated by August 15, 2026.

WhoActive-duty members age 30 and older (about one-third of the active-duty force). Under-30 members may request it voluntarily.
WhatA testosterone-deficiency screening added to the annual PHA troops already complete.
MandatoryThe screening is required for eligible troops. The resulting treatment (TRT) is voluntary.
Ordered byDefense Secretary Pete Hegseth, announced July 15, 2026.

Not yet stated by the Department

When screening begins, or how it phases in across the Army, Navy, Air Force, Marine Corps and Space Force.
How much the added testing will cost.
How a deficiency result is recorded, who can access it, and whether it could affect assignments or a career.

It's contested. Standard guidelines advise against blanket screening of people without symptoms, because levels fluctuate with stress, sleep and illness, and one-time low readings drive overdiagnosis. Physicians and public-health experts have criticized population-wide screening on these grounds, and note TRT carries real risks — reduced fertility, raised red-blood-cell counts, and cardiovascular questions studied in the TRAVERSE trial. A screening number is a starting point for a clinician conversation, not a verdict.

Clinical sequence

How low testosterone is actually diagnosed

Hypogonadism is not "one number below a cutoff." A real diagnosis runs in order: persistent symptoms, confirmed low levels, then a known cause.

Symptoms first Sexual symptoms (low libido, fewer morning erections) carry the most weight; fatigue alone is weak evidence.
Morning, fasting draw Levels peak early, so a proper draw is fasting, around 8–10 AM.
Repeat to confirm A single low value is repeated on a separate morning before it means anything — levels swing with sleep, stress and illness.
Free T + SHBG When total is borderline or SHBG is off (obesity, thyroid, liver, age), free testosterone is what actually matters.
LH & FSH These separate a testicular cause (primary) from a brain/pituitary cause (secondary) — which changes the next steps.
Rule out reversible causes Sleep loss, weight, stress and medications can all lower testosterone with no hormone therapy involved.

Destination: a conversation with a clinician — not a product, and not a self-diagnosis.

Reference range

How the number is read

Ranges vary by lab, assay and guideline. These are general reference points, not decision thresholds.

Total testosterone	How it's generally read
< ~300	Many guidelines (e.g. the American Urological Association) treat this as a level that — with symptoms and on repeat testing — supports evaluation for low testosterone.
~300–400	A gray zone. Where free testosterone and SHBG typically get checked before anyone draws conclusions.
> ~400	Generally not consistent with a low-testosterone picture on its own.

Units are ng/dL. Professional bodies use slightly different cutoffs — the reference range printed on your own lab report is the one that applies to your assay.

Field questions

Straight answers

Is testosterone testing mandatory in the military?

For active-duty members age 30 and older, yes — annual screening is being added to the PHA. Under 30, you can request it voluntarily. Any treatment that follows, including TRT, is voluntary.

Who ordered it, and when does it start?

Defense Secretary Pete Hegseth announced it on July 15, 2026. DoD Instruction 6200.06 (the PHA Program) is directed to be updated by August 15, 2026. An exact start date, cost and phase-in across the services haven't been published.

Is TRT required if my level is low?

No. The screening is mandatory; treatment is not. A low result does not obligate you to start TRT or any therapy. That decision is yours and a clinician's, weighing symptoms, confirmed results, and real risks and benefits.

Could a low result affect my career or deployability?

The Department hasn't publicly detailed how a deficiency result will be recorded, who can access it, or whether it could affect assignments or a career. Because that isn't settled, don't rely on any third-party page (this one included) — confirm through your unit's medical readiness office or an official DoD/branch publication.

Is a single number below 300 a diagnosis?

No. A diagnosis needs persistent symptoms, a repeated low morning measurement, supporting labs (free T, SHBG, LH/FSH), and exclusion of reversible causes. A lone number — especially from a non-morning draw — is a prompt to talk to a clinician, not a conclusion.

Why does draw timing matter so much?

Testosterone is highest in the early morning, so guidelines specify a fasting draw around 8–10 a.m. A later draw can read meaningfully lower and is typically repeated in the morning. Experts note this makes consistent, accurate screening across a large force genuinely hard.

Can I "boost" my number before a test?

This tool won't coach you to game a medical screening — a test that reflects your real physiology is what protects your health. If you're worried, discuss it honestly with a clinician who can account for timing and repeat the measurement properly.
