Professor Deirdre Madden:

I will come back on that point. I am not claiming to be an expert in this area. I have, however, read studies from Professor Susan Golombok and others in the UK. They have done extensive work in following up, through longitudinal studies, children born through surrogacy and donor-assisted reproduction, surrogate mothers and intended parents. Those studies have not reported any negative outcomes concerning the welfare of children born through either donor conception or surrogacy.
