While your embryos are still in the lab, there are a number of techniques that IVF specialists can perform to improve the health your embryos. One such technique is assisted hatching, which may improve your embryos ability to implant in your uterus.
Some couples also ask that their embryos receive a preimplantation genetic diagnosis before being transferred. This diagnostic test allows specialists to transfer only those embryos which are healthiest.
Since many eggs are retrieved and fertilized during IVF, you may be wondering what happen to those embryos that are not transferred back to you. A common procedure for numerous couples is to have the extra embryos cryo-preserved so that they can be used in future IVF cycles if necessary. This is known as frozen embryo transfer.
For couples who aren't sure that IVF is the right form of ART for them, there are alternatives. Some other types of ART include GIFT, ZIFT, and TET.
