Low Testosterone: Symptoms, Tests & Treatment Options
Low testosterone affects millions of men, causing fatigue, decreased muscle mass, and reduced libido. Getting tested is the first step toward understanding your hormone levels and exploring treatment options.
Quick Facts
- What it is: A condition where your body doesn’t produce enough testosterone hormone
- Key tests: Total testosterone, free testosterone, SHBG
- Who should test: Men over 30 with symptoms, those with unexplained fatigue or mood changes
- Cost: $49-$69 for basic testing
Understanding Low Testosterone
Low testosterone, also called hypogonadism or “Low T,” occurs when your body produces less testosterone than normal. This hormone plays a crucial role in male development, muscle mass, bone density, and sexual function.
The condition becomes more common with age. Testosterone levels decline about 1% per year after age 30, though some men experience more dramatic drops. Research suggests that up to 40% of men over 45 have low testosterone levels.
Several factors can contribute to low testosterone beyond normal aging. These include obesity, diabetes, sleep apnea, chronic stress, and certain medications. Injury to the testicles, chemotherapy, and some autoimmune conditions can also affect testosterone production.
The good news? Testing is straightforward and treatment options exist. Many men see significant improvements in their symptoms once they address low testosterone levels with their healthcare provider.

Recommended Tests
A comprehensive low testosterone evaluation typically includes several hormone measurements. The total testosterone test measures all testosterone in your blood, while free testosterone shows the amount available for your body to use. Many doctors also check SHBG (sex hormone-binding globulin), which affects how much testosterone is active in your system.
For the most accurate results, testing should be done in the morning when testosterone levels are naturally highest. Some providers recommend repeating abnormal results to confirm the diagnosis.
Best Testing Services
These lab services offer convenient low testosterone testing with fast results and no prescription required.
Understanding Your Results
Normal total testosterone levels typically range from 300 to 1,000 ng/dL, though this can vary between labs. Levels below 300 ng/dL are generally considered low and may warrant treatment consideration.
However, symptoms matter as much as numbers. Some men feel fine with levels in the 300s, while others experience symptoms even with levels in the normal range. Free testosterone and SHBG results provide additional context for interpreting your total testosterone levels.
Your healthcare provider will evaluate your results alongside your symptoms and medical history. They may recommend additional tests to identify underlying causes or rule out other conditions with similar symptoms.
Frequently Asked Questions
What time of day should I test for low testosterone?
Morning testing between 7-10 AM provides the most accurate results since testosterone levels are naturally highest then. Most testing services will specify the optimal collection window for your sample.
How long does it take to get low testosterone test results?
Most lab services provide results within 1-3 business days. Digital results are typically available through secure online portals, making it easy to share them with your healthcare provider.
Do I need to fast before a testosterone test?
Fasting isn’t required for testosterone testing, though some comprehensive hormone panels may include tests that do require fasting. Check with your chosen lab service for specific preparation instructions.
Can medications affect testosterone test results?
Yes, certain medications including opioids, corticosteroids, and some antidepressants can lower testosterone levels. Discuss your medications with your healthcare provider before testing to understand potential impacts on your results.
