brendan: In responding to your question, I can only tell you my experience. In Feb. 2010 I had a radical and then in summer same year I had 2 months external beam radiation. I was put on hormone therapy which consisted of Lupron & Casadex. Xgeva was added later. My sex life has been almost non existent except to be there for my wife. I wish it were otherwise, but my life is full and healthy. Maybe some day if I ever get off the hormones, there may be some revivial of sex. This is only 1 man's story and you may find other better responses.
Best wishes going forward. A survivor, Ross
