Thank you for your thoughts.
I personaly think that America is more advanced than we are in Australia -at least that was what I thought after much research 2 years ago. The protocols were different at that time. In America, for instance they include a treatment of Doxycycline to ward off any infections prior to starting treatment and then again at transfer. They also give Prednisone, at transfer, which helps fight against immunology factors. Baby asprin again for immunology factors. The progesterone used by American clinics are not available in Australia and yet they are much more effective than suppositories.
The clinics also tend to do quite a number of blood tests to ensure you have not suffered from any potential illnesses that might affect an IVF outcome. For instance, scans checking for tripple layer of your lining to ensure the lining is right for implantation, I have never had this checked in Australia. The thickness of the lining is another issue that clinics in Australia we went to did not check before transfer. These are very important factors that you need to assess to ensure that everything is optimal for implantation to succeed.
I think if you do not have any specific problems, persistence pays out in the end. However, there are a minority group of people that have unexplained infertility which is undianosed infertility. There is a problem and it usually has to do with implantation. Implantation does not take place for an unknown reason even when very good blastocycsts are transfered. When you fit into this category of people then you want to spend your hard earned dollars on getting the very best treatment and sometimes that is not in the country in which you reside.
We started IVF with my own eggs when I was 40 and our clinic (QFG) did not think that at that age we should stop trying. We had poor embryo's and yet they where still trying to suggest that we had a chance. Less than 5% is not really that much of a chance. The probablity of that sort of chance is very remote - hence our move to America and donor eggs. We have still not been successful to date - four trips later. We cannot even get the sort of treatment we require in Australia unless we wait some ridicuious amount of time and even then we may not be able to achieve our altimate goal.
I guess I was hoping that someone would say "hey, we have really have moved ahead here in Australia" to save us the added stress of having to travel so far to get our treatment.
Sorry for the waffle but I feel better with that out
