Frozen embryo transfer (FET) is the process of thawing previously cryopreserved embryos and transferring them into the uterus. It allows couples to have additional IVF attempts without repeating the full stimulation cycle.
Why FET?
FET is used when a fresh transfer was not possible (e.g., OHSS risk), when extra embryos remain after a fresh cycle, or when planning a future pregnancy. It is also used in elective freeze-all cycles which can improve outcomes for some patients.
Preparing for FET
The uterus is prepared with estrogen and progesterone medications to mimic a natural cycle. Lining thickness is monitored by ultrasound. Once optimal (typically 7–8mm+), the transfer is scheduled.
The Transfer Procedure
FET is a simple, painless procedure similar to a cervical smear. A thin catheter places the thawed embryo into the uterus under ultrasound guidance. No anaesthesia is required. You can return home the same day.
Success Rates
FET success rates at Aryamba are comparable to fresh transfers, and in some cases higher — because the uterus has fully recovered from stimulation. Pregnancy is confirmed by a blood test 10–12 days after transfer.
