I am a 65 year old male bodybuilder looking for information. ED started 8 years ago. Viagra and others medicines seem to help when first used 8 years ago, now its not doing the job. I have seen several urologist since my ED started. I'm not sure what lab test where ordered and don't have the results. It seem as if the urologist was writing scripts for Viagra, etc, and was not interested in finding any reasons for my problems. Recently, My Libido has fallen greatly, so I decided to change urologist. He performed a complete physical and included a urine test and blood test. My doctor told me that my free testosterone is low and that he will retest me in 3 months. He did not explain how low my testosterone was or what would be done if my SHBG remains high or if it returned to normal. The only other out of range test was my Total Protein, it was 6.2 with a reference range of (6-4 to 8.9). Here are the results of my blood test:
Testosterone 468 Range 129-767
SHBG 68.7 Range 10-57
Estradiol 26 Range <=56
Any information that you can supply, would be greatly appreciated. Also, is my SHBG high enough to cause my problems?
