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 their 2022 Cochrane review, performed a meta-analysis and combined the results of 32 studies that compared pregnancy outcomes of blastocyst and cleavage stage embryos, and found that blastocysts tend to produce better outcomes.
Researchers in a 2023 study developed a new sperm selection technique that was able to enrich sperm to produce more embryos of a particular sex, with normal IVF and neonatal outcomes.
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.
Researchers in a 2023 study compared fertility outcomes in women trying to conceive who took myo-inositol, probiotic and micronutrient supplements and found no improvements in clinical pregnancy and live birth rates, with contrasting outcomes in time-to-conception based on BMI.
Researchers in a 2023 study found comparable pregnancy and neonatal outcomes when transferring a day 5 poor quality or a day 6 good quality embryo.
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.
