Review Article

The transfer of the human embryo at the blastocyst stage during an in-vitro fertilization procedure is a way of increasing implantation rates. This, in turn, means that significantly fewer embryos are required to be transferred in order to establish a successful pregnancy. The result of this is that high order multiple gestations are eliminated, while maintaining high pregnancy rates, in in-vitro fertilization.
