Low Testosterone Symptoms in Men

Low Testosterone Symptoms in Men — When to Get Tested

If you've been feeling off lately — tired all the time, gaining weight without changing your diet, struggling to build muscle, or noticing a drop in your sex drive — low testosterone might be why.

Testosterone naturally declines about 1% per year after age 30. But for many men, levels drop faster than they should. The problem is that the symptoms are easy to blame on stress, age, or poor sleep — which means low T often goes undetected for years.

Common Symptoms of Low Testosterone

Physical symptoms:

• Persistent fatigue, even after a full night's sleep

• Unexplained weight gain, especially around the belly

• Loss of muscle mass despite regular exercise

• Decreased bone density

• Hair loss or thinning

• Reduced physical endurance

Mental and emotional symptoms:

• Brain fog and difficulty concentrating

• Depression or low mood

• Irritability and mood swings

• Decreased motivation

Sexual symptoms:

• Low libido (reduced sex drive)

• Erectile dysfunction

• Reduced sexual satisfaction

• Infertility concerns

What Causes Low Testosterone?

Low testosterone (also called hypogonadism or "low T") can be caused by a range of factors:

• Age — natural decline after 30

• Obesity — excess body fat converts testosterone to estrogen

• Chronic stress — elevated cortisol suppresses testosterone production

• Poor sleep — most testosterone is produced during deep sleep

• Nutrient deficiencies — zinc, magnesium, and vitamin D all play roles

• Underlying conditions — diabetes, thyroid disorders, and pituitary problems

When Should You Get Tested?

You don't need to wait until symptoms are severe to get tested. A simple blood test can tell you exactly where your testosterone levels stand. We recommend testing if you're experiencing three or more of the symptoms listed above, especially if they've been present for several months.

The standard test measures total testosterone and free testosterone in your blood. For a complete picture, the Hormone & Metabolic Panel also checks estradiol, LH, FSH, SHBG, and thyroid function — which together tell the full hormonal story.
