FET stands for Frozen Embryo Transfer (உறைந்த கரு மாற்றம்). Here is a clear explanation in simple terms — what FET is, why it is used, and how the process works.
FET Meaning in Tamil
FET stands for Frozen Embryo Transfer. In Tamil, it is commonly referred to as உறைந்த கரு மாற்றம் (uraindha karu maatram) — the transfer of a previously frozen embryo into the uterus. It is one of the most widely used procedures in modern IVF treatment.
What Happens in an FET?
During an IVF cycle, eggs are fertilised in the lab to create embryos. Instead of transferring an embryo immediately (a "fresh" transfer), embryos can be frozen using a technique called vitrification and transferred in a later cycle, once the body has returned to its natural hormonal state.
Why Doctors Recommend FET
- Better uterine lining: After hormone stimulation, the uterine lining may not be at its best. FET lets the body recover first.
- Lower OHSS risk: Freezing all embryos reduces the risk of ovarian hyperstimulation syndrome.
- Time for genetic testing: Embryos can be screened (PGT-A) before transfer.
- Use of surplus embryos: Extra embryos from one IVF cycle can be used later without repeating stimulation.
- Lower cost for later attempts: An FET cycle costs significantly less than a full fresh IVF cycle.
The FET Process Step by Step
- Preparing the uterine lining with oestrogen (tablets or patches) to a thickness of around 8 mm
- Adding progesterone to make the lining ready for implantation
- Thawing the embryo in the lab on the day of transfer
- Transferring the embryo — a painless, ultrasound-guided procedure taking about 10 minutes
- Pregnancy test around 12–14 days after transfer

Frequently Asked Questions
What is the full form of FET?
FET stands for Frozen Embryo Transfer — the transfer of a previously frozen embryo into the uterus during IVF treatment.
What is FET called in Tamil?
FET is commonly referred to in Tamil as உறைந்த கரு மாற்றம் (uraindha karu maatram) — frozen embryo transfer.
Is FET better than fresh embryo transfer?
In many cases, yes. FET allows the uterine lining to recover from hormone stimulation, lowers OHSS risk, and gives time for genetic testing before transfer.
Is FET painful?
No. The embryo transfer is a quick, ultrasound-guided procedure that takes about 10 minutes and does not require anaesthesia.
How long after FET can I take a pregnancy test?
A blood pregnancy test is usually done 12–14 days after the frozen embryo transfer.
