I have three children and am absolutely desperate for a fourth, to the point of obsession. My problem is that our third child was born with a genetic condition-cystic fibrosis (that neither of us knew we were carriers for).

Anyway it means that we can't have another child with cystic fibrosis as this could have a considerable negative impact on our son and the new baby.

I know that they can do embryo selection for cystic fibrosis. So my question is does anyone know if they offer embryo screening in Hong Kong and if not, does anyone know anywhere in the world that they do?

Thanks from a very desperate Mum.
