Testosterone Deficiency (Low T)

Testosterone deficiency, often referred to as low testosterone, low T, or hypogonadism, is a medical condition characterized by inadequate levels of the male sex hormone testosterone in the body. This hormonal imbalance can lead to a range of symptoms, including fatigue, reduced muscle mass, low libido and mood disturbances.

At The University of Kansas Health System, our expert team is dedicated to providing top-tier care for testosterone deficiency. We work closely with each patient to create a customized treatment plan tailored to their specific needs, utilizing leading-edge techniques and state-of-the-art diagnostics.

There are 2 types of testosterone deficiency.

The symptoms of testosterone deficiency can vary in severity and may include:

• A reduced interest in sexual activity or a decrease in sexual desire
• Difficulty achieving or maintaining an erection (erectile dysfunction)
• Persistent tiredness and low energy levels
• Mood changes, including feelings of sadness, depression and irritability
• Difficulty in building and maintaining muscle mass, along with weakness
• A tendency to gain weight, especially around the abdomen
• Weakening of bones, which can lead to an increased risk of fractures
• Thinning of facial and body hair
• Difficulty with concentration and memory
• Insomnia or disrupted sleep patterns

There are various causes of testosterone deficiency. Primary causes include:

• Age: Natural aging, especially in older men, can lead to a gradual decline in testosterone levels.
• Testicular conditions: These include genetic disorders (e.g., Klinefelter syndrome), injuries or infections that affect the testicles.
• Testicular cancer: Cancerous growths in the testicles can impair testosterone production.
• Chemotherapy or radiation: Cancer treatments can damage the testicles and reduce testosterone production.

Secondary causes include:

• Hypothalamus or pituitary disorders: Tumors, infections or other issues affecting the hypothalamus or pituitary gland can disrupt the signaling process that stimulates testosterone production.
• Certain medications: Some medications, such as opioids and steroids, can lower testosterone levels.
• Chronic illness: Conditions like obesity, diabetes or chronic kidney or liver disease can contribute to testosterone deficiency.
• Stress and obesity: Chronic stress and obesity can negatively impact hormone levels.
• Lifestyle factors: An unhealthy diet, lack of exercise, and excessive alcohol consumption can contribute to low testosterone levels.

Diagnosing testosterone deficiency typically involves a combination of clinical evaluation, medical history assessment and laboratory tests. Your healthcare provider will ask about your symptoms, medical history and any medications you’re taking. A physical exam may be conducted to look for signs of testosterone deficiency, such as changes in body composition, muscle mass or the presence of gynecomastia (enlarged breast tissue).

The primary diagnostic tool for testosterone deficiency is a blood test to measure your testosterone levels. This test is usually done in the morning when testosterone levels are highest. Low testosterone levels, especially in combination with symptoms, can confirm the diagnosis. Sometimes, other tests may be ordered to determine the cause of the deficiency or rule out other underlying medical conditions. These may include tests to check for pituitary or hypothalamic issues, genetic testing or imaging studies such as an MRI.

Treatment for testosterone deficiency aims to raise testosterone levels back to a healthy range and alleviate symptoms. The choice of treatment depends on the underlying cause and individual patient factors. Treatment options include:

• Testosterone replacement therapy (TRT): TRT involves the administration of synthetic testosterone, often in the form of injections, gels, patches or implants. This helps restore testosterone levels to normal and can alleviate symptoms.
• Lifestyle modifications: In some cases, making lifestyle changes such as adopting a healthier diet, regular exercise, stress management and weight loss can help improve testosterone levels, especially if obesity or other lifestyle factors are contributing to the deficiency.
• Treatment of underlying conditions: If the deficiency is due to an underlying medical condition, such as diabetes or obesity, managing and treating that condition may help improve testosterone levels.
• Medication adjustments: If medication side effects are causing low testosterone, your doctor may adjust your medication regimen or explore alternative options.
• Surgery: In cases of testicular conditions like tumors or certain congenital abnormalities, surgical intervention may be necessary.

Regular follow-up with a healthcare provider is crucial to monitor treatment progress, adjust therapy as needed and ensure there are no adverse effects. For many individuals, especially those on TRT, treatment may need to continue indefinitely to maintain normal testosterone levels and symptom relief. With proper diagnosis and management, many individuals living with low testosterone can find relief from their symptoms and lead fulfilling lives.
