Abstract
There have been pregnancies in several clinics after the replacement of frozenthawed cleaving embryos or expanded blastocysts (1–6). Embryo freezing allows replacement during cycles subsequent to the in vitro fertilization (IVF) cycle and avoids the pressure to replace large numbers of fresh embryos with the attendant risks of multiple pregnancy.
