Some couples will have embryos frozen during their IVF / ICSI treatment cycle. A FET cycle (Frozen Embryo Transfer) is a treatment that involves thawing frozen embryos and transferring them back to the womb.
FET cycles are much simpler than fresh cycles as ovulation induction, egg collection and fertilisation are not required. Success rates with frozen cycles are slightly lower than those with fresh cycles. However MFC is now using state of the art technology with vitrification and this is yielding excellent results.
