Frozen Embryo Transfer (FET)

FET is when eggs that have already been collected, fertilized and frozen in laboratory are transferred into the womb. The management of FET cycles is simpler and cheaper than beginning fresh new cycles. If you have a regular cycle, the embryos are transferred soon after ovulation. If you do not have ovulatory cycles, or the cycle is irregular or absent, the embryos are transferred during an artificial cycle using hormone replacement therapy (HRT) to build up the lining of the womb.
