Is TRT the right treatment for low libido and poor quality erections?

Hello doctor,

I am 47 today. I went to my primary doctor three years ago with low libido and poor quality erections. Blood work came back as total testosterone 381 and A1c 6.9 %. Started exercising and lost weight and inches, 198 lbs to 178, 38-inch waist to 32. Symptoms still persisted. The doctor started me on Clomid 50 mg three times per week. Testosterone shot up to 900's but symptoms persisted although Cialis helped with erection quality, still low libido. Will attach a note with test and A1c results during this time. So, I stopped taking the Clomid in March this year and had my physical last week. The doctor says my testosterone is 570, A1c is 6.0 and everything else looks good. He says since I still have symptoms, that I have testosterone resistance. His analogy was; like diabetics, their bodies produce insulin but just does not know what to do with it. So, his treatment recommendation is TRT along with Clomid. I am hesitant because I feel this therapy is overused nowadays, and I feel pretty good except my libido. Sought a second opinion today from my urologist, he seemed disinterested in me doing that but said if I try a few injections it would not hurt me, then advised me to run this by an endocrinologist. So I guess in summary. Do you believe that testosterone resistance is a valid diagnosis? If I do try the TRT, can I stop after a few weeks or a few injections and get back to the way I am right now with no permanent issues? Should I just start the Clomid again, or just keep using the Cialis and keep working out and trying to clean up my diet more? Any other thoughts and advise would be appreciated. Thanks.

Thank you doctor,

Any history of infertility? None. Any depression? Not that I notice, I feel pretty happy. Any sleep apnea? None. So, you recommend not going back on the Clomid? I had the same thought on testosterone resistance. I have not read into it myself. I am skeptical and not willing to jump into trying this quickly. If I do try a few TRT injections, can I stop without permanent damage, or do you recommend that I do not try it all?
