QUICK ANSWER
Low testosterone (hypogonadism) affects approximately 40% of men over 45 and is characterized by fatigue, decreased libido, muscle loss, weight gain, and mood changes. Diagnosis requires morning lab testing including total testosterone, free testosterone, LH, FSH, and estradiol. Treatment options include weekly injections, daily topical gels, or subcutaneous pellets — all requiring medical supervision and regular monitoring.
Low testosterone — clinically called hypogonadism — is more common than most men realize, and more undertreated than most providers acknowledge. An estimated 40% of men over 45 have clinically low testosterone, yet a fraction of them receive treatment.
The gap between prevalence and treatment isn't because TRT doesn't work. It's because symptoms are often dismissed as "normal aging," testing is infrequently performed, and there are real risks to getting this wrong. This guide covers what you need to know before pursuing testosterone replacement in Fort Myers.
Symptoms of Low Testosterone
The symptoms of hypogonadism overlap significantly with other conditions — which is one reason it's commonly missed:
- Persistent fatigue and reduced energy even with adequate sleep
- Decreased libido and sexual function
- Loss of muscle mass despite consistent training
- Increased body fat, particularly around the abdomen
- Mood changes: depression, irritability, reduced motivation
- Cognitive symptoms: brain fog, reduced focus
- Reduced bone density (long-term, if untreated)
- Decreased body and facial hair
The key is that these symptoms must be correlated with laboratory confirmation of low testosterone. Symptoms alone are not sufficient for a diagnosis — and self-treating based on symptoms without labs is dangerous.
The Right Way to Evaluate Low Testosterone
A proper evaluation includes:
- Total testosterone: Measured in the morning (levels follow a circadian rhythm; afternoon draws can be falsely low)
- Free testosterone: The biologically active fraction; may be low even when total T is normal
- LH and FSH: To distinguish primary hypogonadism (testicular) from secondary (pituitary)
- Estradiol: Testosterone converts to estrogen via aromatase; estradiol must be monitored during TRT
- PSA: Prostate-specific antigen — baseline before starting TRT
- Hematocrit: TRT increases red blood cell production; elevated hematocrit increases clotting risk
- Metabolic panel and CBC: Baseline health assessment
At Solace, Dr. Flávio performs this complete evaluation before any TRT is prescribed. No patient starts treatment without a full lab workup.
TRT Delivery Methods
Testosterone replacement comes in several forms, each with advantages and tradeoffs:
- Weekly injections (cypionate or enanthate): Most common. Effective, cost-efficient, produces predictable peaks and troughs.
- Topical gels/creams: Daily application. Convenient but variable absorption; transfer risk to partners and children.
- Pellets: Implanted subcutaneously every 3-6 months. Consistent levels but invasive insertion procedure.
- Nasal gel (Natesto): Three-times daily application. Preserves fertility better than other methods.
Monitoring While on TRT
TRT is not a set-and-forget treatment. Proper monitoring includes lab work every 3 months initially, then every 6 months when stable. Parameters monitored include testosterone levels, hematocrit, estradiol, PSA, and metabolic markers. Dosing is adjusted based on your response and how you feel — not just hitting a number on a lab report.
Is TRT Safe?
When properly managed, TRT is safe for appropriate candidates with appropriate monitoring. The risks of unmanaged low testosterone — cardiovascular, metabolic, and psychological — often exceed the risks of properly supervised treatment. The key phrase is "properly supervised."
