Many urologist have adopted a penile rehabilitation program. I am not sure whether your urologist has mentioned one to you. In most cases it consists of taking a low dosage of Viagra each day for say a week and then a larger dose for a day and try to stimulate an erection. If this works then you are on your way to recovering erections fairly early. If this does not work there are other interventions that can be done to generate an erection while you wait for the nerve healing to take place to return you to normal erections. One intervention is the use of a vacuum pump along with Viagra (or Cialis, Levitra) to create an erection and to exercise the penis. It is important that the penis is exercised to sustain the elasticity and elongation. The other intervention is the use of penile injections. This is using a small needle and syringe and injecting medication directly into the side of the penis. The medication causes an erection and once the dosage is right then it is about as close to a normal erection as you can get. Of course it is not for everyone as you have to be able to give yourself an injection. The injection itself is done with an insulin type of needle and is just a pin prick. I personally do not like needles but I am able to inject myself without a problem. The quality of the erection compared to one generated with Viagra and the vacuum pump is far better.
Hope this helps.
