I have lived in HK 6 years and am currently going down the DE trail. I have found a clinic in Spain (IVI) which we have just signed up with - in fact just had the last of our pre-visit tests completed today. The waiting list is between 3 - 5 months and they have a fairly high success rate. Here is their website link
Read More and they have an international division that specialises in dealing with English, French & German speaking patients. We have not yet visited in person, but hoping to do that before the end of the year. I will keep posting updates as we progress, in case here is any interest here.
We were basically told by doctors here that we could not get this type of help in HK, so it is inevitable to seek overseas.
