What Happens If We Don’t Have Enough Testosterone?

  • Lower levels of libido including the potential loss of your sex drive
  • Erectile dysfunction (impotence) which may also extend to the loss of morning erections
  • General fatigue
  • Loss of muscle mass and the increased gain of fat
  • Anemia
  • Osteoporosis

  • Obesity
  • Sleep disorders
  • Diseases (including genetic, autoimmune, viral, chronic and cancer)
  • Drugs and treatment (including chemotherapy and radiotherapy)

  • Acne (including on your back)
  • Prostate enlargement
  • Breast enlargement (in men)
  • Sleep disorders
  • Fluid retention
  • Low sperm count
  • Smaller testicles
  • A boost in the number of red blood cells (erythrocytosis
  • Hirsutism (too much hair) in women
  • Female infertility
  • Menstrual problems

If no specific cause can be found for Low T, you may be given drugs that help the body produce more testosterone or be advised to take testosterone supplementation or hormone replacement therapy.
