Testosterone Deficiency

What is it?

When a male has low testosterone levels.

  • It usually affects men ages from late 40- to early 50 years old.

How is testosterone activated and produced

  • Gonadotropin-releasing hormone (GnRH) stimulates the release of two gonadotropins — luteinising hormone (LH) and follicle-stimulating hormone (FSH)- this is activated and regulated/controlled by the pituitary gland in the brain (if this is not functioning correctly it is known as hypogonadism).
  • This process is initiated at puberty.
  • Testosterone is mainly produced in the testes by Leydig cells; however, around 5% is also produced by the adrenal glands (located on the top of each kidney).

  • Testosterone exerts its action through binding to and activation of androgen receptors in the target tissues.
  • It has an important role in the male reproductive system (spermatogenesis requires adequate levels of intratesticular testosterone) and it also influences muscle mass, erythropoiesis(helps red blood cells to be produced) , bone mineral composition, fat metabolism and cognition.

  • If one has total testosterone is <8 nanomol/L and/or free testosterone is <180 picomol/L then consider treat for testosterone replacement therapy.
  • If one has total testosterone between 8-12 nanomol/L then start a trial of testosterone replacement therapy fro six months.
  • If one has total testosterone equal or greater than 12 nanomol/L and/or free testosterone equal or greater than 225 picomol/L then no treatment is needed.
