I want to know if any of the guys have had a problem with impotence since having radiation treatments for any kind of head and neck cancer. Before Jim's cancer diagnosis, we had an excellent sex life. After he went through the surgery and radiation, it has been more than 2 years now and he still can not get an erection. I miss that part of our life, and I know he does too. Do you think that radiation to your neck might affect the pituitary glands or thyroid glands, or some other gland that could this cause the problem? He won't go to the doctor about this because he is embarassed about it, I think.
