What are the signs and symptoms of low testosterone?

The symptoms of hypogonadism may vary from individual to individual. In late-onset hypogonadism many symptoms resemble those of aging and as a consequence this condition is often un-diagnosed.

Symptoms of low testosterone include:

  • Reduced sex drive (libido), difficulty achieving an erection (erectile dysfunction)
  • Increased fatigue and lethargy; diminished energy, sense of vitality, or sense of well-being
  • Depression, anxiety, irritability
  • Difficulty achieving orgasm
  • Decreased muscle mass and strength, reduced exercise stamina
  • Obesity
  • Excessive sweating and night sweats
  • Loss of body, facial and pubic hair
  • Increased breast tissue (gynaecomastia)
  • Poor concentration and/or memory
  • Insulin resistance
  • Loss of bone mass (osteoporosis)
These symptoms are not specific to low testosterone; please see your doctor for diagnosis of any medical complaint.
