Chances me getting pregnant?  Are the odds against me? First off my husband had a vasectamy for his ex wife but then they divorced and he and I married and we want to try for a child of our own.  He had the surgery a little under 7 years ago, and in another post I saw that a man's body can develope antibodies against his own sperm after years of disconnection.    Is this true and how many years does it take?  Also he had rhumatic fever when he was a child which he says can render one sterile.  He has 2 children, but there's a very high chance that they are not biologically his anyway so that doesn't tell us anything.  So we have that goig agaist us, plus there's my situation.  When my mother had cancer I was her primay care giver.  One of her treatments was a high dosage of radioactive iodine and she was to be quarentined for many weeks.  As the weeks went on people could be with her more and more.  However since I was her primary care giver there's a chance I was exposed too much.  Can this cause fertility problems?

Summarized question: Can a vasectomy cause a man to develop antibodies against his own sperm? Can exposure to a patient treated with a high dosage of radioactive iodine cause infertility?
