I can also tell you that my penis came alive on arimidex for a few days. I had an intense feeling of hornyness in it like I used to, perhaps more than I used to.
My penis is not numb now, but i feel no zing in it like I used to when I was arroused.
I have been to many doctors. They are pretty much a waste of time and money. Just read as many studies and books as you can and you will have more knowledge than them about this specific subject. They may be able to provide you with some feedback on their experience with treating patients.
