Low Testosterone
Low testosterone is an epidemic — but it's not a testosterone problem. It's a signal from your body that something upstream is disrupting hormone production. Simply injecting testosterone without finding the cause creates dependency and doesn't address the dysfunction.
Low testosterone in both men and women involves more than a single deficient hormone — it reflects upstream dysfunction in the HPA axis, thyroid conversion, insulin signaling, sleep architecture, and environmental chemical exposure. Signal-Based Medicine™ identifies why testosterone is low rather than simply replacing it, building protocols that restore the body's own production capacity where possible.
Symptoms
- Fatigue and low energy
- Decreased muscle mass
- Increased body fat
- Low libido
- Erectile dysfunction
- Depression and mood changes
- Brain fog
- Poor recovery from exercise
- Sleep disruption
- Decreased motivation
Root Causes
Testosterone production is controlled by a cascade: your hypothalamus signals your pituitary, which signals your testes or ovaries. Chronic stress disrupts the hypothalamus. Poor sleep eliminates the production window (testosterone is primarily produced during deep sleep). Insulin resistance and obesity increase aromatase activity, converting testosterone to estrogen. Environmental chemicals block hormone receptors. Replacing testosterone without fixing these upstream problems means lifelong injections.
Testing
- Total and free testosterone
- LH and FSH (is the signal reaching the glands?)
- SHBG
- Estradiol (aromatase activity)
- DUTCH hormone panel
- Cortisol rhythm
- Insulin and glucose
- VITAL Index assessment
Treatment Approach
We identify why testosterone is low — stress, sleep, insulin, toxins, or pituitary signaling — and correct the upstream dysfunction. When replacement is needed, it's targeted and monitored within the context of your complete hormonal ecosystem.
Frequently Asked Questions
Should I just start testosterone replacement? Not without understanding WHY it's low. If the cause is sleep deprivation, insulin resistance, or stress, testosterone replacement creates dependency without fixing the problem. We find and fix the cause first, then supplement only if needed.
Can women have low testosterone? Absolutely. Women need testosterone for energy, libido, muscle tone, bone density, and cognitive function. Low testosterone in women is common and often overlooked.
Does testosterone replacement cause heart problems? Current evidence suggests properly monitored testosterone replacement does not increase cardiovascular risk and may actually improve metabolic health. The key is proper monitoring — including estrogen conversion and blood counts.
