Freeze All Cycle

A freeze all cycle refers to a cycle of in vitro fertilization (IVF) in which the resulting embryos are frozen for later use rather than transferred right away (fresh transfer). The name ‘freeze all cycle’ refers to the fact that all of the embryos created during a cycle of IVF are frozen in contrast to a fresh transfer where only the extra embryos are frozen.

A freeze all cycle is also called a delayed frozen embryo transfer.
