Dr. Mary Wingfield:

From an emotional and psychological point of view, it is difficult. I was at a webinar a year or two ago where there was a very strong argument made by saying, "How dare you tell me if I have not had a baby that I cannot be a surrogate for somebody else?", so there is an issue about personal autonomy as well and whether it is right for me, as a doctor, or for legislators to say somebody who has not had a baby cannot be a surrogate for somebody else. It is a difficult ethical question. I can see the arguments in favour of that, but from a medical point of view I believe it is important that we try to avoid complications for the surrogate in the future.
