Can PGD be done on frozen embryos?

By Andrea Rodrigo.
Last Update: 01/31/2017

Yes, it is possible to freeze the embryos, thaw them and then do a biopsy to analyze them genetically. In any case, this is not usual. Generally, what is done is to leave the embryos in culture until the day of the biopsy, either on day 3 or day 5.

The protocol to follow will depend on each laboratory and the personal situation of the patients.
