I should add that we do not actually know whether or not we could have conceived naturally with better odds 5, 10, or 15 year ago. At this point in our testing and treatments, the doctors cannot tell us with any certainty why we are having trouble conceiving. They can only speculate and give their professional opinions based on completed trials of studies and previous research in the field of infertility.

Of course, each person and couple is different and the reasoning behind the difficulty of a successful implantation will differ.
