Dr. Mary Wingfield:

I think for medical indications most people in the field would feel that sex selection is justifiable. Dr. Kennedy referred to autism. Again, this is an area that is going to evolve. The situation will change as we go forward, for example, as the diagnosis of autism changes, or Alzheimer's disease. All we can do is deal with it at the moment. There is a concern that international security forces are monitoring this area very closely. In the United States, China and other places around the world the gene editing of embryos is monitored so it is scary and dangerous but the legislation is conservative in that area. We need to be conservative at the moment but, undoubtedly, it will evolve in the next ten to 20 years.
