I have multiple symptoms which I am starting to believe might be low testosterone. I have lost most of the hair on my legs, chest, etc., have had extreme difficulty in getting an erection, have been suffering from memory loss which seems to be getting worse (Dr. has checked for dementia/alzheimers and says not to worry), low energy, muscle definition is disappearing. These symptoms have evolved over the last 10 years but seem to be getting worse at a faster rate. I have just turned 60. I am insulin resistant, but no other health issues. What type of physician should I see?
