Increased use IVF and related techniques has led to an accumulation of over 500,000 frozen surplus embryos in US alone. What to do with them has become an important question. The Catholic Church has condemned IVF from the beginning and considers the problem of frozen embryos as a situation of injustice which in fact cannot be resolved. There are two streams of thought among the Catholic scholars: one proposes that the embryos can be allowed to die with dignity because cryopreservation is an extraordinary means, which can be morally with drawn and the other proposes embryo adoption as only means to rescue the frozen embryos. This paper evaluates these two positions and suggests the first position is more preferable as Catholic position, since many couples prefer to allow the embryos to die than to donate them for adoption.
