Question:
Is it permissible for one to marry someone who, due to some medical treatment to save their life, is physically incapable of having children?
Answer:
It is very good that you are asking and trying to find out what you are supposed to do. This is a serious question, and the answer can only be given, in personal consultation with a competent Rov, in a personal individual manner.
