Testosterone Deficiency

What is testosterone deficiency?

Testosterone is one of the main male sex hormones that your testicles produce and pituitary gland regulates. Testosterone helps manage a wide range of male sexual development and functions, like maintaining your sex drive, sperm production, muscle mass, bone density, and sexual reproductive function. 

What causes low levels of testosterone?

Testosterone deficiencies can be caused by a number of factors, like:

  • Injury to your testes
  • A dysfunctional pituitary gland
  • Chronic illness
  • Obesity
  • Excessive estrogen
  • Severe hypothyroidism


Age is also a natural cause of low testosterone levels, with men losing about 1% of their overall testosterone levels every year after the age of 30.

What are the symptoms of a testosterone deficiency?

A testosterone deficiency can cause a wide range of issues like:

  • Lower sex drive
  • Erectile dysfunction
  • Low sperm count
  • Loss of muscle strength
  • Mild anemia
  • Osteoporosis
  • Weight gain
  • Depression


Symptoms vary from patient to patient, but if you think you suffer from low testosterone, Thyroid Endocrinology and Diabetes can confirm your diagnosis.

How is a testosterone deficiency diagnosed?

The team at Thyroid Endocrinology and Diabetes uses physical exams and blood tests to confirm low testosterone. The physical exam checks your hair, penis, and the size and consistency of your testes and scrotum. Your specialist may also check your peripheral vision, the loss of which could indicate an issue with your pituitary gland. If your blood test shows your testosterone levels are lower than 300 ng/dL, it indicates that you have a testosterone deficiency. 

Once your testosterone deficiency is confirmed, your Thyroid Endocrinology and Diabetes specialist works to find the cause of your low testosterone, if it isn’t age-related. A full blood panel can indicate whether your low testosterone is caused by abnormal thyroid function or other hormonal imbalances.

What treatments do you offer for testosterone deficiency?

At Thyroid Endocrinology and Diabetes, the team treats testosterone deficiency with hormone replacement therapy (HRT). The type of HRT you receive depends on the underlying cause of your low testosterone levels

If testicular failure causes your low testosterone, the team uses testosterone therapy to restore your testosterone levels and any resulting symptoms like bone loss or reduced sex drive. 

If your body isn’t producing enough testosterone because of an issue with your pituitary gland,your provider will optimize your pituitary to return your testosterone levels back to normal. 

If fertility is desired, we can utilize a variety of non-testosterone therapies to restore your testosterone levels.
When we do use testosterone replacement, we will pick out the testosterone replacement formulation (pellets, gels, injections, or patches) that is right for you and will keep your testosterone levels from fluctuating too high or too low.
