Is this the ADAM or qADAM questionnaire?

No. ADAM uses 10 yes/no items (e.g., decreased libido, lack of energy, decrease in strength); qADAM is a validated variant with defined scoring. This page uses an original 0–3 severity scale across 11 domains plus age weighting (max 37)—for visit-prep education, not to replace copyrighted clinical instruments in trials or EHR builds.

How is the testosterone deficiency risk score calculated?

Total = age points (0–4) + sum of 11 domains (each 0–3). Default demo age 52: +3 age; libido 2 + ED 1 + fatigue 2 + muscle 1 + abdominal fat 2 + mood 1 + morning erections 2 + recovery 1 + diabetes context 1 = 13 symptom points → total 16/37 (moderate tier). Young men age <40 get 0 age points but can still score high on symptoms alone.

Can this calculator diagnose low testosterone?

No. Diagnosis requires compatible symptoms plus consistently low morning total testosterone (often confirmed on two draws) and evaluation for pituitary, testicular, medication, and chronic disease causes. A score of 28/37 suggests many domains align with deficiency conversations—it does not authorize self-starting testosterone.

Why does age add points automatically?

Prevalence of biochemical deficiency and symptomatic androgen decline trends upward after 40 in population studies: 40–49 = +2, 50–59 = +3, 60+ = +4. Age 28 with severe libido, ED, and fatigue can reach 21/37 (elevated) with zero age points—proving young pathology is possible despite low age weight.

What testosterone level is considered low?

Guidelines often cite morning total testosterone below ~300 ng/dL (10.4 nmol/L) on reliable assays as supportive of hypogonadism when symptoms coexist—thresholds vary by society and lab. Borderline values need repeat morning testing and sometimes free T if SHBG is abnormal. This checklist does not input lab values.

Should I test saliva or fingerstick testosterone?

Major endocrine societies emphasize standardized serum morning total testosterone from venipuncture. Saliva and capillary kits vary in accuracy and are not substitutes for clinical protocols. Draw before 10 a.m., fasting when possible, and confirm abnormal results per your clinician.

What conditions mimic low testosterone symptoms?

Obstructive sleep apnea (fatigue, ED), depression (low mood, anhedonia), hypothyroidism, iron deficiency, metabolic syndrome, chronic pain/opioids, poor sleep, overtraining, and alcohol use overlap heavily. This calculator adds context points—it cannot distinguish mimics; clinicians screen parallel pathways.

What about prostate cancer and TRT?

Prostate cancer history, elevated PSA, lower urinary tract symptoms, and hematocrit are central to shared decision-making. TRT may be contraindicated or require caution in some contexts. This checklist cannot capture urologic nuance—disclose full history to your prescriber before any hormone trial.

What if I want to preserve fertility?

Exogenous testosterone suppresses intratesticular testosterone and sperm production via HPG axis shutdown. Men pursuing pregnancy need alternative approaches (clomiphene, hCG, gonadotropins) coordinated with urology or reproductive endocrinology—not empiric TRT from a symptom score.

Do over-the-counter testosterone boosters work?

Evidence for OTC “T boosters” (D-aspartic acid, fenugreek, etc.) is generally weak or negative in RCTs; some products are adulterated with undisclosed anabolic steroids or stimulants. Discuss supplements with a pharmacist; abnormal labs need medical workup, not influencer stacks.

What are red flags beyond “low T” symptoms?

Seek urgent care for visual field loss, severe headache with galactorrhea (pituitary mass), acute testicular pain, new firm testicular mass, chest pain, syncope, or stroke symptoms. Unintentional weight loss, night sweats, or fever warrant broader systemic evaluation—not testosterone alone.

Can women use this testosterone deficiency calculator?

It is framed for adult male hypogonadism screening conversations. Women with androgen excess (PCOS) or deficiency have different frameworks, reference ranges, and gender-affirming hormone contexts not modeled here.

What labs might follow an elevated checklist score?

Common pathway: two morning total testosterone measurements, LH/FSH (primary vs secondary pattern), prolactin if indicated, TSH, fasting glucose/A1c, lipids, hematocrit baseline before TRT, and selective PSA per age. Sleep study if STOP-BANG positive for apnea mimics.

Is this testosterone deficiency risk calculator medical advice?

No. It is an educational checklist for classroom and visit-prep use. It does not prescribe TRT, interpret labs, or replace endocrinology or urology assessment.

Endocrine & men's health

Testosterone Deficiency Risk Calculator — Symptom Checklist 0–37

Rate 11 domains from 0 (none) to 3 (severe) plus age context for an educational male hypogonadism checklist (max 37). Pair with sleep apnea screening for fatigue overlap. Not ADAM/qADAM—not diagnosis—not TRT prescription.

Last updated: June 5, 2026

Libido, ED, energy, body composition, morning erections

Diabetes/metabolic and medication context domains

Four-tier bands with lab testing and mimic tables

Symptoms ≠ diagnosis

Higher scores mean “worth discussing morning testosterone and mimics with a clinician”—not “start TRT today.”

Testosterone deficiency risk checklist

Age-weighted symptom and comorbidity points (0–3 each)—education only, not ADAM/qADAM or a diagnosis.

Age (years)

Age contribution in this model: <40 = 0 pts, 40–49 = 2, 50–59 = 3, 60+ = 4 (current: 3).

Reduced sexual desire / libido

Erectile difficulties

Fatigue or low stamina

Loss of muscle bulk or strength

Increased abdominal / central fat

Low mood, drive, or concentration

Fewer morning erections

Poor recovery after exercise

Loss of body hair you attribute to change

Diabetes, prediabetes, or metabolic syndrome care

Score higher if you have diagnosed diabetes or intensive metabolic treatment.

Chronic opioids, chronic steroids, or past anabolic steroid use

Score higher if any apply; be honest—supplements and underground products still matter.

Total checklist score

16 / 37

Moderate burden (10–18) · Age 3 + symptoms 13

Moderate pattern—reasonable to bring this summary to a routine primary care or urology visit.

Many people in this band benefit from screening for sleep apnea, depression, thyroid dysfunction, and metabolic syndrome alongside testosterone testing when indicated.

Clinical visit tips

Ask for morning venipuncture (before 10 a.m. local) when checking total testosterone; confirm abnormal results on a second morning when appropriate.
If fertility is desired, testosterone therapy suppresses sperm production—discuss alternatives with urology or endocrinology.
This checklist is framed for adults with male-typical hormone discussions; people on gender-affirming hormones or with DSD need individualized care not modeled here.

Example scores (computed)

Age 32, no symptoms

10–18	Moderate burden	Bring summary to primary care; screen mimics + morning labs if indicated
19–27	Elevated burden	Earlier evaluation; two morning testosterone measurements per protocol
28–37	High burden	Structured visit—therapy risks (fertility, hematocrit, prostate) need prescriber

Worked example: default demo (score 16/37)

Total = age points + sum of 11 domains (each 0–3). Maximum = 4 + 33 = 37
Age 52 → +3 age-context points
Reduced sexual desire / libido: +2
