What is Hypogonadism?
According to Boston University School of Medicine, low testosterone (also known as “low T”) impacts between 4-5 million adult men in the United States alone. Male hypogonadism, the scientific name for low T, is a medical condition in which the testicles fail to produce adequate testosterone.
Although testosterone is often glamorized for its ability to build muscle mass, the male hormone plays a vital role in a wide range of physiological processes. Over time, inadequate testosterone production can contribute to a number of risk factors and medical conditions, as well as an overall decreased quality of life for many males.
Beginning around age 30, a man’s testosterone levels tend to drop around 1% every year thereafter. By the time they reach age 50 they have a 20% chance of developing low T, although many males experience symptoms well before their 50th birthday.
Reasons for Low Testosterone
When testosterone reaches subclinical levels (usually defined as <300 ng/dL) this is referred to medically as hypogonadism. However, some males may experience symptoms of “low T” with levels well above that reference mark.
The underlying causes of low T can vary. Below we’ll explore common reasons your testosterone may be low.
1. Primary Hypogonadism
Primary hypogonadism is a condition in which the testicles do not produce sufficient testosterone for optimal health, well-being, or development. Generally, primary hypogonadism is the result of a genetically inherited trait or acquired by illness or physical injury.
Inherited Conditions Include:
- Klinefelter’s Syndrome: A medical condition where a male is born with not two, but three sex chromosomes (X, X, and Y).
- Undescended Testicles: Failure of the testes to descend from the abdomen prior to birth
- Hemochromatosis: A condition marked by too much iron in the blood, causing both pituitary and testicular damage
Testicular Damage Leading to Low T
- Physical injury to the testes
- Mumps: an infection that can injure the testicles
- Cancer treatments
2. Secondary Hypogonadism
Damage caused to the hypothalamus and/or the pituitary gland resulting in low T is called secondary hypogonadism. Located in the brain, both of these structures are responsible for coordinating the production of testosterone by the testes.
Inherited Conditions Responsible for Secondary Hypogonadism:
- Kallmann syndrome
- Pituitary disorders caused by tumors, drugs, or kidney failure
- Inflammatory diseases including histiocytosis, sarcoidosis, and tuberculosis
- Aging: as a result of the normal process of aging, particularly after age 40-50
- Obesity: high body fat percentage can impact hormonal efficacy and production
- Medications such as opioids and steroids
- Severe physical or emotional stress such as from illness or surgery
3. Mixed Hypogonadism
This form of hypogonadism is generally more prevalent among older gentlemen. However, those with sickle-cell disease, alcoholism, thalassemia, or who are undergoing glucocorticoid therapy are at increased risk.
