Trophectoderm (TE) biopsy, blastocyst vitrification, and simultaneous single gene disorder (SGD) and comprehensive chromosome screening (CCS) results in excellent ongoing pregnancy rates

      Prospective data now exist demonstrating that trophectoderm biopsy followed by CCS improves the success of IVF by selecting euploid embryos for transfer. Trophectoderm biopsy may also be used when evaluating embryos at risk of inheriting monogenic disorders and has been shown to be safer and more reliable than cleavage-stage biopsy. This study sought to characterize success rates following frozen embryo transfer (FET) of vitrified blastocysts that had been simultaneously screened for aneuploidy as well as a single gene disorder.
