Advanced ART · FET

Frozen Embryo Transfer (FET)

Frozen embryo transfer involves transferring previously cryopreserved embryos into a hormonally-prepared or natural cycle uterus. Modern vitrification has made FET outcomes equivalent or superior to fresh transfer in many settings.

Why FET often outperforms fresh

Endometrial receptivity matters

Fresh IVF cycles can produce supraphysiological hormone levels that may impair endometrial receptivity. FET allows transfer into a more receptive endometrium – either natural or hormonally prepared.

Cycle preparation

Natural vs medicated FET

Natural cycle FET uses the patient’s own ovulation as the trigger. Suitable for regular cyclic patients.

Medicated cycle FET uses oestrogen and progesterone to prepare the endometrium. More predictable timing, suitable for most patients.

Outcomes and safety

Pregnancy and pregnancy outcomes

FET has equivalent or better live birth rates than fresh transfer in many populations. OHSS risk is eliminated. Neonatal outcomes are favourable, with slightly higher birth weights than fresh transfers.

Frequently asked

How long can embryos be frozen?
Vitrified embryos remain viable for many years. Live births have been reported from embryos frozen for over 20 years.
Is FET safer than fresh transfer?
For patients at OHSS risk, yes – elective freeze-all with delayed FET eliminates OHSS risk while maintaining excellent pregnancy outcomes.
Does FET work as well as fresh IVF?
Per-embryo implantation rates are equivalent or better. Cumulative live birth rates from a stimulation cycle now favour freeze-all-and-FET in many indications.
