Sex Hormones Panel
Evaluates key sex hormones to uncover imbalances impacting energy, libido, mood, and long-term health.
Table of contents
Basic data
The sex hormones panel measures critical regulators such as testosterone, estrogen, progesterone, and related markers. These hormones play major roles in energy levels, mood, sexual health, muscle mass, fertility, bone density, and even cognitive function.
Testing is useful for identifying imbalances linked to aging, stress, overtraining, or metabolic dysfunction — and can help guide interventions like lifestyle changes, supplementation, or, in some cases, medical therapies.

Level
Intermediate
Usefulness
High
Detects low testosterone or estrogen levels
Identifies age-related or stress-induced hormonal declines, which may contribute to low energy, low libido, or muscle loss.
Guides lifestyle or therapeutic interventions
Results can support targeted changes in training, stress management, supplementation, or even physician-guided HRT.
Assesses DHEA and SHBG context
Understanding the broader hormonal landscape (including transport/binding proteins like SHBG) improves accuracy of interpretation and intervention.
How it works
Blood sample collection
Usually performed in the morning after an overnight fast. Some panels require testing on specific days of the menstrual cycle (for women).
Lab analysis
Samples are processed using immunoassay or mass spectrometry depending on lab capabilities, with values reported in ng/dL or nmol/L.
Measures
Total and Free Testosterone
Assesses anabolic status, libido, and energy regulation in both men and women.
Estradiol (E2)
Key for menstrual health, bone density, cardiovascular function, and cognition — especially in women.
Progesterone
Helps balance estrogen and supports mood, sleep, and fertility in women.
DHEA-S
Precursor hormone involved in stress response, longevity, and metabolic health.
SHBG (Sex Hormone Binding Globulin)
Regulates the amount of bioavailable testosterone and estrogen — can be influenced by age, liver health, and insulin resistance.
Reliability
Affected by timing and lifestyle
Hormone levels can vary by time of day, stress, diet, alcohol, or training load. Morning collection and context-aware interpretation are essential.
Lab method matters
Immunoassay is commonly used but less accurate at low concentrations; LC-MS/MS is gold standard but more expensive.
Limitations
Can reflect downstream effects
Hormonal shifts may be symptoms of other problems — e.g., sleep deprivation, under-eating, or overtraining.
Individual variability is high
"Normal" ranges differ across labs and individuals; interpretation should consider symptoms and broader context.
Frequency
Suggested cadence
Annually for healthy individuals, or every 6–12 months when adjusting lifestyle or under clinical monitoring (e.g., TRT, HRT, PCOS).
Cost
Typical costs
$50–150 depending on panel depth and lab provider. Some comprehensive hormone panels may exceed this range.
Availability
Where available
Widely available through blood testing labs, functional medicine clinics, and even some telehealth platforms.
Preparation
How to prepare
Test in the morning after an overnight fast. For women, timing in the menstrual cycle matters (e.g., day 3 or luteal phase).
Interpretation
Evaluate ratios, not just absolutes
Testosterone-to-estrogen and free-to-total testosterone ratios can provide deeper insights than total values alone.
Compare against symptoms
Mildly "normal" levels may still correlate with fatigue or mood issues; optimal values are not always within the population average.
Alternatives
Saliva or urine hormone testing
Some protocols use 24h urine or saliva (e.g. DUTCH test) for expanded hormone profiling, though interpretation may be more complex.
DHEA-only or testosterone-only tests
Narrower blood panels are available but provide less context; full panel is preferred.
FAQ
Can I test hormones without symptoms?
Yes, especially if you're proactive about healthspan or have lifestyle factors (e.g. stress, poor sleep) that may disrupt hormones.
Is saliva testing better than blood?
Saliva may better reflect free hormone levels in some cases, but blood remains the clinical standard for most use cases.
