Who FET may help
- Couples who have extra good-quality embryos from an earlier IVF or ICSI cycle
- Women at risk of ovarian hyperstimulation (OHSS), where a fresh transfer is not safe
- When the lining of the uterus is not ready in the fresh cycle
- Couples who want to try again without repeating the egg injections and collection
FET step by step
- PlanningYour doctor reviews your stored embryos and plans the timing of the transfer.
- Preparing the uterusThe lining of the uterus is prepared, either in your natural cycle or with hormone tablets or patches.
- ScansUltrasound scans check that the lining is thick and ready.
- ThawingOn the planned day, the embryo is carefully thawed in the lab.
- Embryo transferThe embryo is placed in the uterus with a thin tube. It takes a few minutes and no anaesthesia is needed.
- Pregnancy testA blood test about two weeks later shows whether you are pregnant.
What to expect
- Fewer injections: no egg-growing injections or egg collection are needed.
- Fewer visits: mostly a few scans and the transfer day.
- Not every embryo survives thawing, though most good-quality embryos do. Your doctor will explain this for your embryos.
- Storage: embryos are stored in liquid nitrogen. Storage is for a limited period under Indian law, and you will be asked to give written consent.
Possible risks
FET is generally a gentle treatment. There may be mild side effects from hormone medicines, and a chance of twins if more than one embryo is transferred. Your doctor will explain these.
Common questions about FET
Are frozen embryos as good as fresh ones?
Good-quality frozen embryos can work as well as fresh ones for many women. Your doctor will talk about your own situation.
How long can embryos be stored?
Indian law sets limits on how long embryos can be stored. We will explain the current rules and your options when you sign the consent forms.
Do I need to rest after the transfer?
No special bed rest is needed. You can return to normal daily activities.
