@daveinflorida The risk of sperm production issues varies depending on the type and extent of treatment, the patient's age, and other factors. Of the people I have had discussions about this issue, who have had radiation, few have had total lack of sperm production. Many have had recovery periods for erections and orgasms with sperm. Some have talked about dry orgasms but that, anecdotally, seemed to be more when people have had their prostate removed. Obviously, that’s a layman’s answer but your doctor may be of more help. I can say that I did have my whole prostate treated plus 2 mm margins and that my orgasms with sperm diminished but did not disappear.
