The latest technique of the
transfer of embryos at blastocyst stage (Day 5 or 6 after retrieval),
rather than on Day 3, serves two purposes: First, it allows for the
selection of the best embryos with the highest pregnancy potential
(since only these survive to Day 5 or 6). Secondly, it allows us to
reduce the risk of creating high order multiples by transferring only
a small number of embryos without adversely affecting the chance of
pregnancy. |
