Ivf with twice frozen & twice thaw embryo?

Jeanne
Anyone ever dove PGS on "already frozen" embryos? How was the result of the twice frozen & twice thaw embryo transfer? I find myself in that dilemma now     Trying to decide if it is worth doing or not ? How would the quality of the embryos be after 2nd thaw? My doctor is not helpful that much and just left it up to me to decide; I even had to ask about the PGS myself after this 4th muscarriage which showed trisomy 8. Your inputs are appreciated. Thanks
