Understanding Low Testosterone

Low testosterone, medically known as hypogonadism, occurs when your body doesn’t produce enough of this crucial hormone. Testosterone levels naturally decline with age, dropping about 1% per year after age 30.

The condition affects approximately 5.6% of men aged 30-79 years, yet many cases go undiagnosed. Beyond aging, several factors can contribute to low testosterone including obesity, diabetes, chronic stress, and certain medications.

Your testosterone levels peak between 8-10 AM and gradually decline throughout the day. This morning surge makes early testing crucial for accurate diagnosis, which is why doctors prefer blood draws before 10 AM.

What makes testosterone testing unique compared to other hormones? Your levels can vary by up to 40% throughout a single day. Sleep quality, exercise timing, and even seasonal changes affect your results more than you might expect.

Symptoms to Watch For

Recognizing low testosterone symptoms isn’t always straightforward. Many men dismiss early warning signs as normal aging or stress.

  • Persistent fatigue that doesn’t improve with rest
  • Decreased sex drive and erectile dysfunction
  • Mood changes, including depression and irritability
  • Loss of muscle mass despite regular exercise
  • Difficulty concentrating and memory fog
  • Unexplained weight gain around the midsection
  • Hot flashes and night sweats
  • Reduced bone density and increased fracture risk

The tricky part? These symptoms overlap with other health conditions. That’s why testing provides the clarity you need rather than guessing based on symptoms alone.

Recommended Tests

A comprehensive low testosterone evaluation starts with total testosterone, measuring both bound and free hormone levels in your bloodstream. Free testosterone shows the active hormone available to your tissues, typically 1-2% of your total levels.

Bioavailable testosterone combines free testosterone with weakly bound hormones, giving you a clearer picture of what’s actually working in your body. Many doctors consider this the most clinically relevant measurement.

Advanced panels often include luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These tests reveal whether low testosterone stems from testicular problems or pituitary gland dysfunction, completely changing your treatment approach.

Understanding Your Results

Normal total testosterone levels typically range from 264-916 ng/dL for healthy men, though reference ranges vary between laboratories. Levels below 300 ng/dL often indicate deficiency, while results between 300-400 ng/dL warrant symptom evaluation.

Free testosterone becomes concerning when it drops below 6.5-7.5 pg/mL, depending on your age. Remember that reference ranges reflect population averages, not necessarily optimal levels for you personally.

Single test results can mislead due to daily fluctuations, recent illness, or stress. Most endocrinologists recommend confirming low results with a second morning test before starting treatment discussions.

Your symptoms matter more than numbers on a lab report. Some men feel terrible with “normal” levels, while others function well with technically low readings.

Treatment Options Available

Testosterone replacement therapy comes in several forms, each with distinct advantages. Topical gels provide steady hormone levels but require daily application and careful attention to skin contact with others.

Injectable testosterone offers convenience with bi-weekly or monthly dosing, though levels fluctuate more between injections. Newer options like testosterone pellets provide 3-4 months of steady hormone release through a simple office procedure.

Before considering replacement therapy, lifestyle modifications can significantly impact your natural production. Weight loss, strength training, adequate sleep, and stress management often improve levels without medication.

Frequently Asked Questions

What time of day should I test my testosterone?

Test between 7-10 AM when testosterone peaks naturally. Testing later in the day can show falsely low results, potentially leading to unnecessary treatment.

How accurate are at-home testosterone tests?

Blood-based at-home tests processed by certified labs match clinic accuracy when collected properly. Avoid saliva tests for testosterone as they’re less reliable than blood measurements.

Can I eat before a testosterone test?

Fasting isn’t required for testosterone alone, but many hormone panels include glucose or lipid tests that do require 8-12 hours of fasting. Check your specific panel requirements.

How often should I retest my testosterone levels?

Men with normal levels typically retest every 2-3 years. Those on testosterone therapy need monitoring every 3-6 months initially, then annually once levels stabilize.

Will exercise before testing affect my results?

Intense exercise within 24 hours can temporarily lower testosterone levels. Schedule your test for a rest day or after light activity only.
