For men with ED problems after treatment for Postrate cancer there are injectable medicine available that could help. I am a 3 year survivor of postrate cancer and like the gentleman on the radio, the pills(Viagra, Cialis) did nothing for me. I use a medicine called TRI-MIX with good results. It is an injection into the side of the penis but that is not a painful as it sounds since most of the nerve cells are located in the head of the penis, not the side. Talk to your Doctor about TRI-MIX. Be aware that it has to be prepared at a mixing pharmacy which are not permitted in PA., my medication is shipped from NJ. This medication is not expensive, about $80-$100 per 5ml which could be 10-20 doses based on individual dose requirements. Best news is that my medical coverage pays for this prescription. It has saved my sex life and I'm always surprised that PA doctors aren't more aware. I had to tell my urologist about it. More information can be found about TRI-MIX on the web.
