Low testosterone in young males, also known as male hypogonadism, can have several possible causes. Here are some of the most common causes:

• Primary hypogonadism: This occurs when there is a problem with the testicles themselves, which can be caused by:

  • Klinefelters Syndrome
  • Undescended testicles
  • Hemochromatosis
  • Testicular injury
  • Chemotherapy
  • Radiation
  • Aging

• Secondary hypogonadism: This occurs when the testicles are normal but function improperly due to a problem with the hypothalamus or pituitary gland. Causes of secondary hypogonadism include:

  • Pituitary disorders
  • Inflammatory disease
  • HIV/AIDS
  • Medications
  • Obesity

• Acquired conditions: These can include:

  • Obesity
  • Diabetes
  • Chronic liver or kidney disease
  • COPD
  • High cholesterol levels
  • High blood pressure
  • Drinking excessive amounts of alcohol
  • Using illegal drugs

• Congenital causes: These are inherited traits that can cause hypogonadism.

If you suspect that you might have low testosterone, make an appointment with your doctor. They can use a simple blood test to determine your testosterone level and help you identify the underlying cause of your symptoms.
