@heisenberg34 I have the same exact conditions as you have - zero libido, no erections, no morning erections, some slight libido stimulation when looking at porn, which is highly infrequent for me. I'm 78 years old also. Just no spontaneous libido, sadly enough. I do need an Rx from an endocrinologist (I've seen 3 endocrinologists by now) to get the Free-T medication. But my Free-T is in the normal range now and still no normal sex drive. No doctors have any support or answers or any program for trial. Maybe a sex therapist would have things to try. I've been to 3 urologists and most just said get a penile implant. That's not for me. I think the answer is buried somewhere in male hormone imbalances/levels such as serotonin and/or dopamine, I need to research it more, figure out dosage levels. I tried aromatase inhibitors on and off, and they made no difference. I at one time thought that the estrogen the body generates when taking the T injections was causing the problem, but that did not pan out. I see the endocrinologist in a few weeks, but my hopes are not high that he will have any ideas for me. There may always be a breakthrough however! If I find out something, I'll let you know. I think supplements are not successful either. Neither were Viagra, Cialis, etc.
