Could You Have Low T?
The ADAM questionnaire is a clinically validated screening tool with 88-97% sensitivity for low testosterone. 10 questions. 2 minutes.
Signs of Low Testosterone
Testosterone declines about 1-2% per year after age 30. The American Urological Association estimates low T affects roughly 2 in every 100 men. Many live with it for years, chalking symptoms up to aging or stress.
Many men live with low testosterone for years and chalk it up to aging or stress. The ADAM questionnaire is a quick first step. If you screen positive, focused HPG-axis bloodwork is what confirms it and points your provider to the right protocol. The Asymmetric Health team works under clinical protocols built and overseen by our founder.

What is Low Testosterone?
Testosterone is the primary male sex hormone, produced mainly in the testes. It regulates sex drive, bone density, fat distribution, muscle mass, red blood cell production, and sperm production. The Endocrine Society defines low testosterone (hypogonadism) as a total testosterone level below 300 ng/dL confirmed on at least two morning blood draws.
Testosterone levels naturally decline 1-2% per year after age 30 (Baltimore Longitudinal Study of Aging). But aging alone doesn't explain the full picture. A population-level study in JCEM found that men today have significantly lower testosterone than men the same age 20 years ago, suggesting environmental and lifestyle factors are accelerating the decline.
The HIM study (Hypogonadism in Males) found that 38.7% of men aged 45 and older had total testosterone below 300 ng/dL. Many had never been tested.
Low T is more than a number. It affects energy, mood, sexual function, body composition, cognitive performance, and long-term health. Left untreated, it is associated with increased risk of metabolic syndrome, cardiovascular disease, and osteoporosis.
What Causes Low Testosterone?
About the ADAM Questionnaire
The Androgen Deficiency in Aging Males (ADAM) questionnaire was developed by Dr. John Morley at Saint Louis University. It has a sensitivity of 88% for detecting low testosterone. A positive screen (answering "yes" to question 1 or 7, or "yes" to any 3 questions) warrants confirmatory blood work.
This quiz is a screening tool, not a diagnosis. Lab work is the only way to confirm your testosterone levels and build a treatment plan.
Frequently Asked Questions About Low Testosterone
What testosterone level is considered low?
The Endocrine Society defines low testosterone as a total testosterone below 300 ng/dL, confirmed on at least two morning blood draws.
However, "optimal" and "low" are different things. Many men with levels in the 300-500 range still experience significant symptoms. Free testosterone and SHBG levels also matter, which is why a single total T number doesn't tell the full story.
At what age does testosterone start declining?
Testosterone begins declining around age 30 at approximately 1-2% per year, according to the Baltimore Longitudinal Study of Aging. By age 45, nearly 40% of men have levels below 300 ng/dL.
Lifestyle factors like sleep quality, body composition, stress, and metabolic health can accelerate or slow this decline.
Can low testosterone be reversed without TRT?
In some cases, yes. If your low T is driven by modifiable factors like insulin resistance, obesity, poor sleep, chronic stress, or thyroid dysfunction, addressing those root causes can restore natural production.
For men with primary hypogonadism (testicular failure) or significant age-related decline, testosterone replacement therapy is typically needed.
What's the difference between total and free testosterone?
Total testosterone measures all testosterone in your blood, including the portion bound to SHBG and albumin. Free testosterone is the unbound portion your body can actually use.
You can have a "normal" total T but low free T if your SHBG is elevated, which is why both should be tested.
Is this quiz the same thing as getting my blood tested?
No. The ADAM questionnaire is a validated screening tool that identifies men who are likely to have low testosterone. It is not a substitute for blood work. A positive screen means you should get comprehensive hormone testing to confirm your levels and identify the root cause.
How accurate is the ADAM questionnaire?
The original validation study found the ADAM questionnaire has 88% sensitivity for detecting biochemically confirmed low testosterone. It has high sensitivity (catches most true cases) but lower specificity, meaning some men who screen positive may have normal levels.
That's why blood work is always the next step.
What happens if I screen positive?
A positive result means proper blood work is the logical next step. At Asymmetric Health, the Focused Hormone Evaluation ($299) covers the male hormone axis (total and free testosterone, estradiol, SHBG, LH/FSH, PSA) plus the supporting markers needed to dose treatment safely, with a 60 minute consultation with your clinician.
