Yes, my husband is having surgery next week and he was told to buy a pump so that he is ready for rehabilitation. Using a pump is important not only for obtaining erection but also to make sure that urethra stays normal length (to prevent it getting shorter) which is important for continence. The instructions were to use a pump 3 times a day to "exercise" the tissue. He was also prescribed Cialis 5 mg before the surgery and after surgery nurse wants him to start using higher dose to encourage blood circulation and nerve regeneration. So perhaps you might try a pump to prevent atrophy and than see how it goes from there.
