Symptoms
- Low libido, reduced spontaneous erections
- Fatigue, low motivation, mood change
- Decreased muscle mass and strength; increased body fat
- Poor sleep; loss of morning erections
- Decreased bone density over time
Testing
Diagnosis requires consistent symptoms plus low morning total testosterone, confirmed on a second morning draw. Free testosterone, LH, FSH, prolactin, SHBG, and estradiol help distinguish primary vs. secondary hypogonadism and guide treatment. Sleep apnea, obesity, chronic opioid use, alcohol, and certain medications should be assessed.
Lifestyle levers
- Resistance training and regular aerobic exercise
- Weight optimization — even modest loss raises T in overweight men
- Quality sleep and treatment of obstructive sleep apnea
- Alcohol moderation; avoid anabolic steroids and unregulated "boosters"
- Adequate protein, zinc, vitamin D, and healthy fats
Medical therapy
When testosterone replacement therapy (TRT) is indicated, options include gels, injections, and pellets — chosen based on preference, fertility plans, and monitoring practicality. Fertility-preserving options (clomiphene, hCG) are appropriate for men who wish to conceive. All TRT requires monitoring (hematocrit, PSA, symptoms).
What supplements can and cannot do
No supplement replaces TRT for symptomatic hypogonadism. Correcting vitamin D or zinc deficiency, and general metabolic support, may help men whose labs are borderline. Marketing claims of "T-boosters" outpace evidence — professional-grade formulations chosen for the underlying metabolic issue are more useful than a generic booster.
