Answer to Question #1453 Submitted to "Ask the Experts"

Category: Pregnancy and Radiation — Conception after exposures

The following question was answered by an expert in the appropriate field:

Q
I've had doctors tell me different things. I had radiation 131I 14 years ago. I was wondering if I can get pregnant. Some doctors say yes and some say no, that I won't be able to have children because of the radiation. I have read that you are supposed to have the treatment during your menstrual cycle if you are of childbearing years. At the time of my doses I was not. Is there a chance of me being able to get pregnant?
A
It is virtually impossible that you received enough radiation from the 131I to render you sterile. Thus, you should be able to get pregnant without difficulty. Some alarmists might express concern that you could have an abnormal child as a result of the radiation. However, the likelihood of an abnormal child from other "spontaneous" causes is much greater than that from the radiation. All this says is that if you want a child you should proceed as if you had never had the radiation. In all fairness, however, there could be extenuating circumstances in your case. You should consult with your physician if you are concerned. Best wishes for your future family.
