Researchers in a 2023 study found decreased adverse pregnancy and neonatal outcomes in those who performed a natural vs medicated FET, including abnormal birth weights, preeclampsia, preterm births, and more.
Researchers in a 2023 study share the results of a survey that evaluates the use and attitude of natural cycle FETs in US clinics, which some studies have recently shown can lead to improved pregnancy outcomes compared to medicated FETs.
Researchers in a 2023 study evaluated factors affecting pregnancy outcomes after euploid transfer, and found that double euploid transfer, BMI, type of FET protocol, and the day of embryo biopsy all had an impact.
Researchers in a 2023 study discovered 6 genes associated with recurrent miscarriage of euploid embryos, which were found to impair reproductive ability in mouse models.
Evidence up to 2022 shows that a single PGT-A biopsy is highly concordant (similar) with the rest of the embryo when the embryo is aneuploid or euploid, but not when it’s mosaic or segmental.
