Unfortunately, there can be multiple reasons why an embryo does not implant. It can depend on the age of the woman providing the eggs (the younger the better), the stage of development of the embryo (5 days may be better than 3), and, to a lesser extent, the appearance of the embryo, the chance that any one embryo will be successful can be frustratingly low. Also, if male factor is an issue, then you may want to consider ICSI, where a single live sperm is directly injected into the egg. Also some research indicates that frozen embryos may be more successful than fresh. You may also want to consider the number of embryos that you transfer. transferring more than one may well improve your odds.
