Normal testosterone levels help men maintain energy level, healthy mood, fertility, and sexual desire. A decrease in testosterone can cause diminished libido, erectile dysfunction, muscle weakness, loss of body hair, depression, and other mood disorders.

  1. Do you have a decrease in libido (sex drive)?
  2. Do you have a lack of energy?
  3. Do you have a decrease in strength and/or endurance?
  4. Have you lost height?
  5. Have you noticed a decreased "enjoyment of life?"
  6. Are you sad and/or grumpy?
  7. Are your erections less strong?
  8. Have you noticed a recent deterioration in your ability to play sports?
  9. Are you falling asleep after dinner often?
  10. Has there been a recent deterioration in your work performance?
