Nerves alone: Damage to the nerves during prostatectomy is enough to cause ed. See your urologist to discuss options.

Please seek 2nd opin: This is a complex matter far beyond the limitations of a q&a forum. Schedule a second opinion with a specialist.

See a urologist: Post prostatectomy erectile dysfunction is treatable. An evaluation by a urologist may determine the reasons, talk to you about chances for recovery and also and more importantly give you treatment options.
