The Science Behind Testosterone Replacement Therapy

Testosterone in Healthy Men

  • It is produced in the testicles.
  • Regulates: bone density, muscle mass, sex drive, and sperm production.
  • Peaks in early adulthood and begins to decline around 40 years.
  • Normal range: 300 to 1000-1200 nanograms per deciliter

Low Testosterone

  • Levels lower than 300ng/dl need to be assessed to make sure they aren’t due to simple aging.
  • Low T is the underproduction or lack of testosterone production
  • Causes can be diabetes, infection, obesity, chronic medical conditions like liver or kidney disease, or other hormonal conditions.
  • Symptoms are: change in sleep patterns, reduced sex drive, sexual dysfunction, infertility, emotional changes, decreased strength, loss of bone density, weight gain.
  • Diagnosis: includes comprehensive physical, blood work, health history.

Low Testosterone Treatments

  • Testosterone injections are the recommended treatment to avoid the transfer and to maximize efficiency.
  • hCG and estrogen blockers are also prescribed
  • There are also gels, patches, and putty — however, their efficacy is suspect and gels can be accidentally transferred to family members or loved ones on contact.
