I'm looking for any advice or, hopefully,success stories about using frozen embryos? We have just had our third failed ICSI/IVF cycle....got today, which is disappointing and sad. We have 3 blastocytes on ice. We are now deciding whether to transfer them immediately, or wait for a full cycle to pass. Has anyone had any experience with this....is it best to wait a cycle? what are the success rates of FET?
