You've answered your own question in that you need to find another doctor. One thing I don't have a good answer for is why when there's a problem with an individual why so many physicians tend to shrug it off if their initial treatment options don't pan out. As for a recommendation, obviously I'm going to recommend lowtestosterone.com - things may be a little different for you compared to an older man but regardless you will be put on the right track and quite possibly remedy the problem once and for all.
