Embryo freezing is done for those who embryos are extra and, can opt for cryo preservation. Your chances of becoming pregnant with a thawed frozen embryo are not affected by the length of time the embryo has been stored. But not all embryos will survive freezing and eventual thawing when they come to be used. Very occasionally no embryos will survive. Occasionally the transfer is canceled due some reason then your embryos can be frozen and then used later, if you happen to be pregnancy the first time the frozen embryos can be used to conceive the second time.
