Frozen Embryo Transfer(FET)
procedureDefinition
An IVF cycle in which previously cryopreserved (frozen) embryos are thawed and transferred into a prepared uterus.
In IVF Treatment
FET cycles are less physically demanding than fresh cycles since no stimulation or retrieval is required. Published outcomes can be comparable to fresh transfer and sometimes differ by patient context, embryo details, and clinic protocol; lining preparation is managed by the clinic.
Frequently Asked Questions
How is the uterus prepared for a FET?
Either in a natural/modified natural cycle (monitoring for the body's own ovulation) or with hormone replacement (estrogen to build the lining, then progesterone for timing). Your doctor will choose based on your situation.
Are FET success rates better than fresh transfers?
Published outcomes can be comparable between FET and fresh transfer, and some studies show differences in selected situations. Your clinic can explain how embryo details, lining preparation, diagnosis, and protocol affect the choice.
