Causes Of Low Energy In Men

A number of conditions that can lead to fatigue in men:

Low Testosterone

Testosterone is the primary sex hormone in men. During puberty, it’s responsible for things like deepening your voice and causing hair to sprout. Testosterone also helps regulate sex drive, fat burning and storage, sperm production, red blood cell production, and even your mood.

Testosterone levels decline with age (roughly 1 to 1.5 percent less per year after around age 30), but for some men, the drop is faster. When a significant drop in T levels occurs, it can cause your energy levels to plummet, along with a slew of other symptoms, including:

  • Reduced sexual drive or low libido
  • Loss of body hair
  • Loss of muscle
  • Erectile dysfunction
  • Increased body fat
  • Loss of strength
  • Enlarged breast tissue
  • Inability to concentrate
  • Depression
  • Low sperm count


Low T is clinically considered anything below 300 nanograms per deciliter (ng/dL) of total testosterone (total T) or free testosterone levels that are below 1 to 2 percent of your total T (1). Low T is usually marked by a constellation of symptoms: low energy, weight gain around the mid-section, brain “fogginess,” sexual difficulties, and more.

Testosterone helps your body build and maintain muscle mass. It also helps muscles pump and contract, playing a key role in your body’s energy-producing systems. Without it, your muscles won’t work at their peak abilities, you might gain fat, you’ll feel less motivated.

If your physician suspects that low T could be to blame for your lagging energy levels, testing is key. Hone’s analysis for low testosterone, along with other hormones that can impact your health. If a test indicates that you do have low T, hormone replacement therapy can help relieve your fatigue and other symptoms.
