Could it be low testosterone? Take the quiz.

How this questionnaire is scored

The original ADAM scoring rule counts the screen as positive if you answer yes to question 1 (decreased libido) or question 7 (weaker erections), or if you answer yes to three or more of the remaining eight questions. This tool applies that exact rule and nothing else.

Why it has low specificity

Several ADAM questions, including low energy, low mood, and poor sleep, are common symptoms of many conditions unrelated to testosterone, from depression to sleep apnea to thyroid disease. That overlap is why ADAM is used as a screening prompt, not a stand-alone diagnostic test.

What a real diagnosis requires

Diagnosing low testosterone requires blood testing, typically drawn in the morning on two separate days, since testosterone naturally fluctuates. A clinician interprets those results alongside your symptoms and history, not a questionnaire score alone.

Frequently asked questions

What is the ADAM questionnaire?

ADAM stands for Androgen Deficiency in Aging Males. It is a 10-question yes or no screening tool published by Morley and colleagues in 2000, designed to flag symptoms associated with low testosterone and prompt a conversation with a clinician.

How is the ADAM questionnaire scored?

The screen is considered positive if you answer yes to question 1 (decreased libido) or question 7 (weaker erections), or if you answer yes to any three of the other eight questions. This tool applies that same original scoring rule.

Does a positive ADAM screen mean I have low testosterone?

No. A positive screen means your symptoms overlap with those associated with androgen deficiency, but the questionnaire has low specificity. Many of its symptoms, like fatigue or low mood, have other common causes unrelated to testosterone. A positive screen is a reason to discuss testing with a clinician, not a diagnosis.

What should I do after taking this questionnaire?

Bring your answers to a licensed healthcare provider along with any symptoms you want to discuss. A diagnosis of low testosterone requires blood testing, typically on two separate mornings, not a questionnaire alone.
