# Icsm Avoid Universal Testosterone Screening

> This skill advises against universal testosterone screening in asymptomatic men, recommending testing only when specific clinical indications are present. Trigger phrases include 'should I screen everyone for low T', 'is universal testing appropriate', or considering testosterone order in an asymptomatic patient.

# Avoid universal screening for low testosterone

## STEP 1 — Gather Information
Collect presence of hypogonadism symptoms (low sexual desire, decreased morning erections, erectile dysfunction) and screen for associated conditions (obesity, type 2 diabetes mellitus, metabolic syndrome, HIV infection, opioid/glucocorticoid use, bone density loss, male infertility). If any symptom or associated condition is present, proceed to step 2; otherwise, do not order testosterone testing.

## STEP 2 — Rule In / Rule Out
Obtain a morning (07:00–11:00) fasting total testosterone level using a reliable assay. If the level is <12 nmol/L (3.5 ng/mL) on two separate occasions, proceed to step 3; if not, rule out hypogonadism and do not initiate testosterone therapy.

## STEP 3 — Classify or Stratify
Determine whether hypogonadism is functional (associated with obesity, T2DM, MetS, opioid/glucocorticoid use, chronic illness) or organic (primary/secondary with identifiable etiology such as genetic disorder, testicular injury, or pituitary dysfunction). This classification guides subsequent management decisions.

## STEP 4 — Decide
For functional hypogonadism, prioritize treating the underlying condition (e.g., weight loss, glucose control) and consider testosterone therapy only if symptoms persist after intervention; for organic hypogonadism, offer testosterone therapy if symptomatic and after shared decision‑making, targeting mid‑normal total testosterone range.

## Clinical Guardrails / Mimics / Pitfalls
Do not order testosterone screening in asymptomatic men without specific indications; do not treat isolated low testosterone without clinical symptoms; avoid using testosterone solely to improve depression, bone density, or cardiovascular risk without proven benefit; remember that obesity‑related low testosterone often improves with lifestyle modification alone.

## Concrete Clinical Example
A 58‑year‑old man with BMI 34 kg/m² and fatigue but normal libido and erections requests a testosterone test. Screening reveals no hypogonadism symptoms and no other indications (no diabetes, HIV, opioid use). Per guideline, testosterone testing is not ordered; instead, evaluate sleep quality and depression.
