The role of routine serum testosterone testing: routine hormone analysis is not indicated as an initial screening test in the evaluation of erectile dysfunction.

A 60-year-old male physician is self-referred to your office for evaluation of his erectile dysfunction, which has been worsening for 5 years. He reports his erections rarely achieve fullness for penetration, and he is unable to ejaculate. He has tried sildenafil citrate (Viagra(R); Pfizer Inc, New York, NY) with mild success in the past. He has a strong libido and feels healthy. He rarely exercises, but is on his feet most of the day at work. He has been healthy his whole life and never seeks a doctor's attention. He has no other medical problems. His only medication is a baby aspirin once a day. His physical examination, including genitalia, is normal. As part of his initial visit, should his serum testosterone level be checked by his urologist?
