Should I Get Tested?

Twelve questions. The output is a reading list and a conversation plan, never a diagnosis.

Everything you enter stays in this browser. Nothing is sent to a server.

  1. Has your interest in sex dropped noticeably over the last several months?
  2. Have erections become less frequent or less firm, including morning erections?
  3. Do you feel persistently tired in a way that sleep doesn't fix?
  4. Have you lost muscle or strength despite training the same way?
  5. Have you gained fat around the middle without a clear change in diet?
  6. Has your mood been flatter, more irritable or lower than is normal for you?
  7. Do you have trouble concentrating or feel mentally slower than you used to?
  8. Have you had hot flushes or sweats, or noticed breast tenderness or enlargement?
  9. Have you been diagnosed with type 2 diabetes, obesity or sleep apnea?
  10. Have you taken opioids or glucocorticoids (such as prednisone) for an extended period?
  11. Have you been told you have osteoporosis or had a low-trauma fracture?
  12. Have you had a testicular injury, undescended testicle, chemotherapy or a pituitary problem?

How This Works

The first eight questions cover the symptom domains clinical guidelines describe as suggestive of testosterone deficiency: sexual, physical and psychological. The last four cover conditions and exposures in which the same guidelines say a test is reasonable even without classic symptoms.

The tool sorts your answers into one of three reading lists. More "yes" answers in the sexual-symptom items, or any "yes" in the context items, moves you toward the list that starts with how a diagnosis is made. Fewer "yes" answers moves you toward the list that starts with the many non-hormonal causes of the same symptoms. There is no score threshold because no questionnaire has one that replaces a blood test.

Frequently Asked Questions

Is this a diagnosis?
No. It is a sorted reading list. Low testosterone is diagnosed from symptoms plus repeated morning blood tests, interpreted by a clinician. No questionnaire, including validated ones like ADAM, can replace the blood test.
What are the questions based on?
The symptom items follow the domains the Endocrine Society and American Urological Association guidelines list as suggestive of testosterone deficiency. The context items are conditions and exposures in which those guidelines say measuring testosterone is reasonable even without classic symptoms.
Why do you ask about diabetes and opioids?
Because both are strongly associated with low testosterone and are common. Guidelines specifically mention men with type 2 diabetes, obesity, long-term opioid or glucocorticoid use, HIV-associated weight loss, osteoporosis and pituitary disease as groups where a test is worth considering.
What should I ask for at the appointment?
A morning total testosterone, repeated if low, and depending on the result free testosterone or SHBG, LH and FSH. Also mention sleep, medications and mood, because several things that cause these symptoms are not hormonal.
Is anything saved?
No. Your answers stay on the page and are gone when you leave it.
