When Should Men Get Hormone Testing? Which Tests Are Necessary?
Hormonal imbalances in men can manifest across a wide spectrum — from fatigue to decreased sexual desire, from depression to muscle loss. Many men drag on for years, attributing these symptoms to “aging” or “stress.” Yet a simple blood test can reveal the underlying hormonal cause. In this guide, we explain when and which hormone tests men should get.
Which Hormones Should Men Monitor?
The main hormones affecting men’s health:
| Hormone | Site of Production | Primary Effect |
|---|---|---|
| Testosterone | Testes (Leydig cells) | Sexual function, muscle, bone, mood |
| LH (Luteinizing Hormone) | Pituitary | Stimulates testosterone production |
| FSH (Follicle-Stimulating Hormone) | Pituitary | Stimulates sperm production |
| Prolactin | Pituitary | If elevated, suppresses testosterone |
| DHEA-S | Adrenal gland | Precursor hormone; energy, immunity |
| Estradiol (E2) | Adipose tissue (aromatization) | If elevated: gynecomastia, sexual dysfunction |
| SHBG | Liver | Affects free testosterone |
| TSH, fT4 | Thyroid | Energy, metabolism, sexual function |
| Cortisol | Adrenal gland | Stress hormone; testosterone antagonist |
| Insulin / HbA1c | Pancreas | Metabolic health; associated with ED risk |
When Should You Get Hormone Testing?
Situations That Absolutely Require Testing
1. Sexual Dysfunction
- Decreased libido (sexual desire)
- Erectile dysfunction
- Difficulty reaching orgasm
- Ejaculation problems
2. Physical Changes
- Significant decrease in muscle mass
- Rapid fat accumulation in the abdominal area
- Reduction in body and facial hair
- Breast enlargement (gynecomastia)
- Bone fractures (under age 50)
3. Psychological and Neurological Symptoms
- Chronic fatigue and loss of energy
- Unexplained depression
- Difficulty concentrating, memory problems
- Lack of motivation, apathy
4. Infertility or Desire for Children
- If pregnancy has not occurred within 12 months of regular sexual intercourse
- Abnormalities in sperm analysis
5. Other Indications
- History of anabolic steroid use
- History of chemotherapy or radiotherapy
- Suspected pituitary tumor (the triad of headache + visual disturbance + sexual dysfunction loss)
- Chronic kidney or liver disease
- Diagnosed diabetes or obesity
As Routine Health Screening (Even Without Symptoms)
| Age | Recommendation |
|---|---|
| Age 40 | First baseline testosterone measurement |
| Ages 45–50 | PSA, testosterone, thyroid screening |
| Age 50+ | Annual testosterone and metabolic panel |
Which Tests Should Be Ordered?
Basic Male Hormone Panel
For initial evaluation:
- Total testosterone — baseline measurement
- Free testosterone — biologically active portion
- SHBG — for calculating free testosterone
- LH — differentiation between primary and secondary
- FSH — sperm production assessment
- Prolactin — if elevated, indicates a pituitary problem
- Estradiol (E2) — aromatization assessment
Additional tests (when indicated):
- TSH, free T4 (thyroid function)
- Cortisol (morning, baseline)
- DHEA-S (adrenal reserve)
- HbA1c, fasting blood glucose (diabetes screening)
- Complete blood count (polycythemia risk)
- Liver enzymes (AST, ALT)
- Lipid panel
- PSA (over age 40, before TRT)
The Best Time for Testing: Between 8–10 AM
This critical point is often overlooked.
Why in the morning?
Testosterone follows a circadian rhythm; between 8–10 AM is the highest point of the day. A sample taken in the afternoon may measure testosterone 30–40% lower. This difference can lead to a diagnosis of “low testosterone.”
Other important points:
- Fasting or after a light breakfast: fasting is preferred for standard evaluation
- Not after intense exercise: acute stress affects cortisol and SHBG
- 48 hours after alcohol consumption: alcohol temporarily lowers testosterone
- Not during illness: acute illness affects all hormones
Is a Single Measurement Sufficient?
No. A single measurement result is not sufficient for diagnosis.
- A low result should be repeated with a 2–4 week interval
- Both measurements should be done in the morning, fasting, and at the same laboratory
- The reference ranges of the same laboratory should be used (different laboratories use different methods)
Who Should Interpret the Results?
Men’s hormone tests should be evaluated by the following specialties:
| Specialist | Indication |
|---|---|
| Urology | Sexual dysfunction, infertility |
| Andrology | Comprehensive male reproductive health |
| Endocrinology | Pituitary diseases, thyroid, adrenal |
| Internal Medicine | General metabolic evaluation |
A general practitioner can also order tests; however, specialist referral is recommended for complex hormonal disorders.
The Problem of Misinterpreting Reference Values
The “normal range” on laboratory reports is calculated based on a broad population. Even if a man appears “within the reference range” at a testosterone value of 350 ng/dL, if he is experiencing significant symptoms, the symptom + value combination should be the basis for evaluation.
Free testosterone: Even if total testosterone appears normal, if SHBG is high, the biologically active portion may be low. For this reason, measuring free testosterone is critically important.
Cost of Hormone Testing (Turkey 2026)
| Test | SGK Coverage | Private Lab Fee |
|---|---|---|
| Total testosterone | If indicated | 150–400 TL |
| Free testosterone | Partial | 200–500 TL |
| LH, FSH | Yes | 150–300 TL each |
| Prolactin | Yes | 150–300 TL |
| SHBG | Partial | 200–400 TL |
| Full panel (urology/andrology) | Variable | 800–2,500 TL |
Tests ordered by a urologist at SGK-contracted institutions are largely covered.
What to Do Based on Test Results?
| Result | Recommendation |
|---|---|
| Total T > 400 ng/dL + no symptoms | Follow-up, continue lifestyle |
| Total T 200–400 ng/dL + symptoms present | Repeat test + specialist evaluation |
| Total T < 300 ng/dL + symptoms | Confirm in two separate measurements → treatment plan |
| High prolactin | Pituitary evaluation with MRI |
| Low LH/FSH + low T | Secondary hypogonadism → pituitary screening |
| High LH/FSH + low T | Primary hypogonadism → testicular evaluation |
Frequently Asked Questions
Which doctor should you see for hormone testing? For the first step, you can consult a general practitioner or internist. If sexual dysfunction or infertility is suspected, going directly to a urology or andrology specialist is more efficient.
If testosterone is low, will medication be started immediately? No. First, correctable causes are investigated (obesity, sleep apnea, medication side effects). Lifestyle changes are tried. Medical treatment (TRT) is considered when the criterion of low testosterone + symptoms is met in two separate measurements.
How often should retesting be done? Every 3–6 months for patients who have started TRT. Once every 1–2 years after age 40 if there are no symptoms.
