Transfer of frozen embryos from one center to another

Couples have the right to have their embryos transferred from one center to another. If the center is outside the United Kingdom HFEA has to be informed.

The first step to transfer embryos from one centre to another is to write to the centre which has the couple's embryos stored in order to release the embryos. Consent from both partners is required.
