Assisted hatching

After the embryos are trasferred into the uterus pregnancy will occur only if the embryo can escape or "hatch" from its shell (called zona pellucida). In some cases the embryos have a very thick zona which may lead to th cause of implantation failure. Making a small hole in the zona, called assisted hatching, before embryo transfer will benefit those cases.
