The ADAM Questionnaire: What It Is and What It Isn't

The ADAM questionnaire — Androgen Deficiency in the Aging Male — is a short screening tool developed in the late 1990s to flag possible low testosterone in men. It is used widely because it is quick and sensitive. It is also widely misunderstood: it is a screening tool, not a diagnosis. This guide explains what it measures, what its score does and does not mean, and what should happen next. Educational information only, not medical advice.

What the questionnaire asks

The classic ADAM questionnaire asks ten yes-or-no questions about symptoms commonly associated with declining testosterone:

• Do you have a decrease in sex drive?
• Do you lack energy?
• Have you lost strength or endurance?
• Have you lost height?
• Have you noticed a decreased enjoyment of life?
• Are you sad or grumpy?
• Are your erections less strong?
• Have you noticed a recent deterioration in your ability to play sport?
• Are you falling asleep after dinner?
• Has there been a recent deterioration in your work performance?

A "yes" to specific questions (classically the first question, or question seven, or any three others) is often treated as a positive screen. Exact scoring conventions vary, which is itself a sign of the tool's limits.

What a positive screen means

A positive ADAM screen means symptoms consistent with possible androgen deficiency are present. It does not mean testosterone is low. The questionnaire is deliberately broad, which is why:

• Sensitivity is high — it catches most men who do have low testosterone.
• Specificity is low — many men with a positive screen have completely normal testosterone. Fatigue, low mood, poor sleep and stress produce the same symptom pattern.

In other words, the ADAM questionnaire is good at not missing people, and bad at not over-flagging them. That is the correct design for a first screen — but it means the score alone must never drive treatment.

The symptoms that matter most

Clinicians look for clusters of symptoms rather than a single one, and weight them differently:

• Sexual symptoms — reduced libido and weaker erections — are among the more specific to androgen deficiency.
• Physical changes — loss of muscle, strength, body hair, and increased fatigue.
• Mood and cognition — low mood, irritability, poor concentration.

None of these is specific on its own. Many other conditions — thyroid disease, depression, sleep apnoea, medication effects, chronic illness — produce the same picture, which is exactly why testing and clinical judgement are essential.

What happens after a positive screen

1. Blood testing. The standard next step is a morning blood draw measuring total testosterone, usually with additional markers such as free testosterone, sex-hormone binding globulin, luteinising hormone and follicle-stimulating hormone.
2. Repeat testing. Because testosterone fluctuates, a single low reading is usually confirmed with a second morning sample.
3. Looking for causes. The clinician distinguishes primary (testicular) from secondary (pituitary or hypothalamic) causes, and checks for reversible contributors such as obesity, sleep apnoea, medication and stress.
4. Treatment only if indicated. Testosterone therapy is considered when symptoms and confirmed low levels align, and when the risks and benefits have been discussed.

How the app uses it

The app's ADAM score records your answers and symptom pattern so you can discuss them with a clinician. It is a note-taking and preparation tool — not a diagnostic device. Bring the result to a consultation, alongside a symptom history and any previous blood results.
