TRT Overview

  • Concerns: Major crisis with men’s testosterone levels
    • Statistics: 30-year-olds now have the same levels as 60-year-olds did 30 years ago
  • Causes of Low Testosterone:
    • Increased body fat leads to more testosterone conversion to estrogen
    • Poor sleep quality affects hormone production

Symptoms of Low Testosterone

  • Common Symptoms:
    • Low libido
    • Low energy and mood
    • Low muscle mass
    • Poor recovery from workouts

Diagnosis and Measurement

  • Key Measurements:
    • Total and free testosterone
    • FSH (Follicle Stimulating Hormone)
    • LH (Luteinizing Hormone)
    • Estradiol (Estrogen levels)
  • Understanding Results:
    • Importance of free testosterone
    • The role of androgen receptors

TRT Treatment

  • Approach:
    • If symptoms are present and measurable low testosterone, consider TRT
    • Trial period to assess improvement
  • Treatment Options:
    • Direct testosterone supplementation
    • HCG for brain-related testosterone issues
    • Clomid or Enclomiphene for estrogen receptor blocking

Monitoring and Side Effects

  • Common Side Effects:
    • Acne and hair loss
    • Potential increase in blood pressure
    • Risk of testicular shrinkage with direct testosterone
    • Hematocrit increase (blood thickening)
  • Impact on Heart Health:
    • Slightly increased risk of heart attacks initially, but potentially reduced risk over time
  • Long-term TRT usage can lead to infertility due to decreased sperm production.
  • Blood pressure monitoring is essential, especially for those at higher cardiovascular risk.
  • Testicular shrinkage can occur without proper balancing of FSH and LH.

Long-term Considerations

  • Commitment: TRT could be a lifelong treatment
  • Reproductive Considerations: Can affect fertility
  • Regular Monitoring: Regular blood work to monitor testosterone and associated hormone levels

Myths and Misconceptions

  • TRT is not equivalent to synthetic steroids used by athletes/bodybuilders.
  • There's no significant evidence linking TRT with increased prostate cancer risk.
  • Estrogen blockers often discouraged unless estrogen levels are excessively high.

Conclusion

  • Importance of Professional Guidance: Avoid non-medical sources for hormone management
  • Final Advice: Consider lifestyle and health factors before starting TRT
  • TRT should be monitored by a knowledgeable urologist or endocrinologist.
  • Lifestyle factors such as diet, exercise, and sleep should be optimized before initiating TRT.
  • The importance of individualized care and ongoing evaluation in hormone therapy. Back
