CONDITION
Low Testosterone (Low T) in Men
Symptoms, causes, testing, and modern treatment — from the clinical team at Vital Society.
The short answer
Common symptoms of low testosterone
Symptoms rarely appear all at once. Most men describe a slow slide over months or years and only connect the dots after multiple systems are affected.
- Persistent fatigue that sleep doesn't fix
- Loss of morning erections; reduced libido or performance
- Loss of muscle mass and strength despite training
- Increased body fat, especially around the midsection
- Brain fog, low motivation, mood changes, irritability
- Poor sleep quality and disrupted recovery
- Reduced confidence, drive, or 'edge'
What causes low testosterone?
Age-related decline
Testosterone drops roughly 1% per year after 30. Combined with modern lifestyle stressors, this often produces symptomatic Low T decades earlier than most men expect.
Metabolic and lifestyle factors
Poor sleep, chronic stress (elevated cortisol), obesity, insulin resistance, excess alcohol, and endocrine-disrupting chemicals all suppress testosterone production.
Primary vs. secondary hypogonadism
Primary is a testicular problem (the signal is fine, the factory isn't producing). Secondary is a brain-signal problem (the hypothalamus/pituitary aren't sending the right LH/FSH signal). Both are treatable — but the workup and supportive medications differ.
How Low T is properly diagnosed
A proper workup looks at more than one number. At Vital Society we run a comprehensive panel that includes:
- • Total and free testosterone
- • SHBG (sex hormone binding globulin)
- • Estradiol (E2), LH, FSH, prolactin
- • Thyroid panel (TSH, free T3, free T4)
- • Metabolic markers (fasting insulin, HbA1c, lipids)
- • CBC, comprehensive metabolic panel, PSA
Labs are drawn in the morning when testosterone peaks. "Normal" reference ranges are based on population averages — including men who feel terrible — so we treat the patient in front of us, not the range printed on the paper.
Treatment options
Testosterone Replacement Therapy (TRT)
Injectable testosterone cypionate 2–3× per week is our preferred method — stable levels, precise dose adjustments, no pellets to crash off of. Home-delivered; patients self-inject.
LH-support medications
Enclomiphene, hCG, or gonadorelin preserve testicular function, size, and fertility. Selected based on your goals.
Estrogen management
Some testosterone converts to estradiol. Balance — not suppression — is the goal. We monitor E2 and adjust protocol frequency before reaching for aromatase inhibitors.
Lifestyle optimization
Sleep, resistance training, protein intake, alcohol reduction, and body-fat reduction meaningfully move testosterone. TRT works better when the foundation is solid.
What to expect on TRT
- Weeks 2–4: better mood, mental clarity, morning erections return
- Weeks 4–8: improved energy, libido, sleep quality
- Months 3–6: body composition changes, strength gains, full symptom resolution
- Ongoing: labs every 8 weeks for the first 6 months, then every 3 months
Frequently asked questions
What testosterone level is considered 'low'?+
Most labs flag total testosterone under ~300 ng/dL as low, but symptoms often appear well before that — many men feel awful in the 350–450 range. Free testosterone and SHBG matter as much as total. We treat symptoms confirmed by labs, not a single cutoff.
At what age does testosterone start to drop?+
Testosterone declines roughly 1% per year after age 30. Modern lifestyle factors — poor sleep, chronic stress, obesity, endocrine disruptors — are accelerating that drop, and it's now common to see clinically low levels in men in their late 20s and 30s.
Can low testosterone cause ED?+
Yes. Low T reduces libido and can contribute to erectile dysfunction, though ED is usually multifactorial (vascular, neurological, hormonal, psychological). Optimizing testosterone often improves ED, and pairing TRT with PDE5 inhibitors like tadalafil produces the strongest results.
Will TRT shrink my testicles or affect fertility?+
Standalone testosterone suppresses natural production and can reduce sperm count and testicular size. We routinely pair TRT with LH-support medications (enclomiphene, hCG, or gonadorelin) when preserving fertility or testicular function matters to you.
How quickly does TRT work?+
Most men feel improved energy, mood, and libido within 4–8 weeks. Full benefits — body composition, strength, sleep quality — typically stabilize between 3 and 6 months.
Do I need TRT forever?+
Optimization is a long-term commitment: benefits generally last only while treatment continues. If you choose to stop, a structured taper with supportive medications can help restart natural production.
