Causes of Low Testosterone | Symptoms & When to Test
Causes of low testosterone are often overlooked, even though this condition is quite common. Many people don’t realize they have low testosterone because the symptoms can be subtle at first.
If you are experiencing low energy, reduced libido, or mood changes, low testosterone may be the underlying cause.
In this guide, you’ll discover the main causes of low testosterone and how lab testing helps identify the exact reason accurately.
What is Testosterone?
Testosterone is a primary sex hormone mainly produced in the testicles in men. It is also present in women in smaller amounts, produced by the ovaries and adrenal glands.
This hormone plays a key role in:
- Sexual drive
- Muscle growth
- Bone density
- Sperm production
- Mood and energy levels
Any imbalance in testosterone levels can significantly affect overall health and quality of life.
What Causes Low Testosterone?
Low testosterone can result from several factors, which can be grouped into the following categories:
1. Medical Causes
Pituitary Gland Disorders
The pituitary gland controls hormone production. Any dysfunction can reduce testosterone levels.
Testicular Problems
Injuries, infections, or reduced function of the testicles directly impact hormone production.
Chronic Diseases
Conditions such as:
- Diabetes
- Liver disease
- Kidney disease
can disrupt hormonal balance.
Thyroid Disorders
Both overactive and underactive thyroid conditions can affect testosterone levels.
2. Lifestyle-Related Causes
Obesity
Excess body fat can convert testosterone into estrogen, lowering its levels.
Poor Sleep
Lack of sleep reduces overall hormone production.
Chronic Stress
High cortisol levels suppress testosterone production.
Poor Nutrition
Deficiencies in key nutrients like zinc and vitamin D can reduce hormone levels.
3. Natural Causes
Aging
Testosterone levels naturally decline with age, especially after the age of 30.
4. Medication-Related Causes
Certain medications may lower testosterone levels, including:
- Antidepressants
- Corticosteroids
- Hormonal treatments
