FET (frozen embryo transfer)
A frozen embryo transfer uses an embryo frozen in an earlier cycle, thawed and placed in the uterus later. It lets the body recover from stimulation and is now very common.
FET (frozen embryo transfer) is a transfer that uses an embryo frozen during an earlier cycle, thawed and placed into the uterus at the right point in your cycle.
Why freeze first
Freezing lets your body recover from stimulation before transfer, and it makes good use of extra embryos from one egg retrieval. Modern freezing (vitrification) means survival rates after thawing are high.
For the full guide, including when it's used and how well it works, see FET explained.
