One complication I've had is that my libido went away completely about 4 years ago. Prior to that, I had occasional ED issues which were embarrassing. So I tackled the libido issue and finally found that working with an endocrinologist that my Free-Testosterone had gone down to basically nil. Now, I'm taking testosterone cypionate injections in my upper thigh once a week and find the additional T is helpful in restoring libido, but not to a miraculous level. At least I am getting erections in the middle of the night on occasion. I always thought that without libido, getting a penile implant would be not useful. I saw a urologist for it but decided not to go for it.
