The Real Causes of Low Testosterone


Low testosterone (low T) affects 4 to 5 million men in the US.
Testosterone is an important hormone in all human bodies, male and female, but is higher and more commonly associated with men. Testosterone naturally starts to decrease each year after age 30, which in some men this can be substantial. It’s not just older men that are affected by low T, young men, even babies, and children, can also have this problem. The key is to recognize the signs of low T and have your levels checked regularly, then to attempt to understand where the dysfunction has originated.

The primary symptoms of low T are actually pretty basic; fatigue, mental cloudiness, moodiness, fat gain, loss of muscle mass, low bone density, a decrease in mood, decrease in sexual desire and lastly low libido.

There are two types of hypogonadism, being primary and secondary hypogonadism which are the causes of Low Testosterone.

Primary hypogonadism

Underactive testes cause primary hypogonadism. That’s because they don’t manufacture sufficient levels of testosterone for optimal growth and health. This underactivity can be caused by an inherited trait or by accident or illness.

Inherited conditions include:

  • Undescended testicles: When the testicles fail to descend from the abdomen before birth
  • Klinefelter’s syndrome: A condition in which a man is born with three sex chromosomes: X, X, and Y.
  • Hemochromatosis: Too much iron in the blood causes testicular failure or pituitary damage

Types of testicle damage that can lead to primary hypogonadism include:

  • Physical injury to the testicles: Injury must occur to both testicles to affect testosterone levels.
  • Mumps orchitis: A mumps infection can injure testicles.
  • Cancer treatment: Chemotherapy or radiation can damage testicles.

Secondary hypogonadism

Secondary hypogonadism is caused by damage to the pituitary gland or hypothalamus. These parts of the brain control hormone production by the testes.

Inherited or disease conditions in this category include:

  • Pituitary disorders caused by drugs, kidney failure, or small tumors
  • Kallmann syndrome, a condition connected to abnormal hypothalamus function
  • Inflammatory diseases, such as tuberculosis, sarcoidosis, and histiocytosis, which can impact the pituitary gland and the hypothalamus
  • HIV/AIDS, which can affect the pituitary gland, hypothalamus, and testes

Acquired circumstances that can lead to Low T include:

  • Normal aging: Aging affects production and response to hormones.
  • Obesity: High body fat can affect hormone production and response.
  • Medications: Opioid pain meds and steroids can affect the function of the pituitary gland and hypothalamus.
  • Concurrent illness: Severe emotional stress or physical stress from an illness or surgery can cause the reproductive system to temporarily shut down.

You may be affected by primary, secondary, or a mixed hypogonadism. Mixed hypogonadism is more common with increased age. The acquired circumstances can be dealt with through a more balanced lifestyle and a higher level of self-care.
