Testosterone naturally decreases with age, significantly impacting testosterone levels, especially in older men. Low testosterone can lead to conditions like Testosterone Deficiency Syndrome (TD) or Low Testosterone (Low-T), presenting symptoms such as:

  • Reduced libido
  • Fatigue
  • Decreased muscle mass
  • Irritability
  • Erectile dysfunction
  • Low mood

These symptoms may also occur due to factors like diabetes, obesity, medication side effects, thyroid issues, or cholesterol problems. Non-specific symptoms connected to TD include lower energy, reduced endurance, compromised memory, difficulty articulating thoughts, and a general decline in focus affecting work performance.


Diagnosing testosterone deficiency involves evaluating total blood testosterone levels and considering specific signs and symptoms. A comprehensive medical examination includes a health history review, physical assessment, and scrutiny of reported symptoms.

Diagnostic blood tests measure total testosterone, assess luteinizing hormone (LH) for causes, and examine blood prolactin for potential pituitary issues or tumors. Additional diagnostic measures include evaluating haemoglobin, Follicle Stimulating Hormone (FSH) for sperm functionality, an estradiol hormone test for breast-related symptoms, an HbA1C blood test for diabetes, an MRI of the pituitary gland, bone density tests, and chromosome tests.


The common treatment for testosterone deficiency is testosterone replacement therapy (TRT), using injections or transdermal methods like gels, creams, liquids, or patches, typically lasting around four days. Regular blood tests are needed to monitor testosterone levels during the treatment.

Potential TRT side effects include redness, itching, and back pain for gels and liquids; serious allergic reactions for injections; and potential swelling, pain and rare hematoma for testosterone pellets. During TRT, there’s an elevated risk of increased red cells and potential disruption of normal sperm production, which can be a concern for those planning parenthood.
