Danish scientists reported today that children born from IVF after being frozen as embryos fare better than IVF embryos not frozen. The report at the meeting in Barcelona of the European Society for Human Reproduction and Embryology showed higher birth weight, less congenital problems, and fewer admissions to a neonatal intensive care unit, when compared to "fresh" IVF embryos.
This is hardly an endorsement for freezing your embryos first during IVF, but it is another indication that embryos that have been frozen are still quite healthy. Such embryos need not be discarded, but can be rescued and brought to term, even many years after being put into the freezer.
