Frozen Embryo Replacement (FER)

Good quality spare embryos remaining from your IVF related treatment may be frozen and stored for use in a future cycle. Initially frozen embryos can be kept for five years; this can be extended to ten years in certain circumstances. You will be required to complete the relevant consent and HFEA forms.

The frozen embryos are thawed and transferred into your womb, either in a natural menstrual cycle or in hormone replacement cycle. Unfortunately, despite the precautions that are taken, not all embryos survive the freezing and thawing process. Thus reduced success rates can be expected from the frozen embryos.

There is an initial charge of freezing embryos, which includes storage for one year. Following this you will be sent annual reminders and accounts so it is important to inform the clinic of any changes of address.
