What This Quiz Measures
This quiz uses the ADAM questionnaire (Androgen Deficiency in the Aging Male), a 10-item symptom screener developed at Saint Louis University and widely used in primary care to decide who should get a testosterone blood test. It is sensitive to the symptoms of low testosterone — low libido, fatigue, loss of strength, and mood changes — but it is not specific: many of these symptoms have other causes, from poor sleep and stress to thyroid problems and depression.
That is why a "higher likelihood" result does not mean you have low testosterone, and a "lower likelihood" result does not rule it out. It means your symptom pattern is worth a conversation with a clinician and, if appropriate, a simple morning blood test.
How Testosterone Is Actually Measured
Testosterone is measured from a blood sample, ideally drawn in the morning (roughly 7–10 a.m.) when levels peak, and usually confirmed with a second test on a different day. Labs typically report total testosterone and sometimes free testosterone. General adult male reference ranges commonly run from about 300 to 1,000 ng/dL, but the exact cutoff that defines "low" — and whether treatment is warranted — is a clinical judgment your provider makes alongside your symptoms.

Servicemembers: How This Connects to the New Screening
In July 2026, the Pentagon announced it will screen servicemembers aged 30 and older for low testosterone every year during their annual health assessment, with testosterone-replacement therapy offered as an opt-in if treatment is recommended. Members under 30 can volunteer to have their levels checked. If this quiz flags symptoms, you do not have to wait for your annual assessment — you can ask your military medical provider about a blood test now.
