This is our fifth IVF attempt. Unfortunately, in our case, the risks of multiple pregnancy were not fully explained by our clinic or our consultant. I think that they should give you a lot more information when you start.
We were never told much about the risks of multiple births and always had two put back. But after failure after failure, over the years we started to investigate via the web and think more about the risks.
Because it is our fifth attempt, we feel that it is taking too much of a chance to risk a twin pregnancy. We want the best for our babies and think that is best achieved by trying for one child at a time, not to mention that I would not like to have a premature birth.
So we have opted for single blastocyst transfer, even though it cuts down our chances of success. It would be just too much for us to lose a child just because we wanted to increase our chances. This is our individual decision and not intended as a criticism of anyone else.
