What Causes Low Testosterone?

If your suffering from symptoms of low testosterone levels you're probably wondering, "why me?" The truth is in most cases there's nothing you could have done to prevent yourself from having lowered testosterone. The only real exceptions are people who abuse illegal anabolic steroids and people leading risky lifestyles leading to their contraction of HIV/AIDS and tuberculosis.

Doctor on what causes low testosteroneThere are two categories of underlying factors behind lowered testosterone. When the cause is in the testosterone producing organs is referred to as “primary hypogonadism.” When the cause is in the pituitary gland it is called “secondary hypogonadism.” When the problem is related to the hypothalamus it is referred to as ”tertiary hypogonadism.

Primary Hypogonadism:

  • Undescended testicles – If the testes fail to migrate from inside the abdomen into the scrotum during fetal development or in the first year or two of life, the testes may become damaged and unable to produce adequate amounts of testosterone.
  • Injury to the scrotum – If the testes are injured, they may not be able to produce adequate testosterone. Damage to one testicle does not often to lead to low levels if the other testis remains normal.
  • Cancer therapy – Chemotherapy and radiation therapy can damage the interstitial cells in the testes responsible for testosterone production. This decrease in testosterone production may be temporary as the cells recover, or it may be permanent.
  • Aging – Testosterone levels decrease with aging. Usually, enough testosterone is manufactured to allow for adequate bodily functions.
  • Mumps orchitis – The mumps virus can cause inflammation of the testes in males, and if the illness occurs in puberty or adulthood, the damage to the testes may lead to low testosterone production. Immunization against the mumps has significantly decreased the incidence of this illness.
  • Chromosomal abnormalities – A normal male has one X and one Y chromosome (a normal female has two X chromosomes). In Klinefelter’s syndrome, in males, an extra X chromosome is present and among other anatomic issues, there is abnormal development of the testes and decreased ability to manufacture testosterone.
  • Ovary conditions in women – Premature ovarian failure and surgical removal of both ovaries (bilateral oophorectomy) are conditions associated with lower circulating testosterone levels.

  • Pituitary Gland Damage – Damage to the pituitary gland may occur because of tumors of the gland itself or because of damage caused by the side effects of treatment of nearby brain tumors.
  • Malformed Hypothalamus –  Hypothalamus malformations can prevent normal function. Kallman’s syndrome is one example.
  • Circulation Problems – Compromised blood flow to these glands from other conditions such as excessive systemic blood loss.
  • Disease Induced Inflammation – Inflammation caused by tuberculosis and sarcoidosis may affect the pituitary gland.
  • HIV/AIDS Induced Inflammation – HIV and AIDS may also cause inflammation of both the hypothalamus and pituitary.
  • Non-Prescribed Medications – Illegal use of anabolic steroids, for example in body building, can cause hypogonadism and low testosterone levels.

Symptoms of Low Testosterone
