A 2025 study introduces the FORTUNE model, developed from over 10,000 PGT-A cycles, that uses age, ovarian reserve, partner age, and BMI to predict how many euploid embryos a patient is likely to produce by grouping patients into five prognosis categories.
A large 2025 study charts how AMH levels decline with age in over 22,000 women, revealing when diminished ovarian reserve (DOR) becomes more common, regardless of infertility status.
A 2024 study compared successful and unsuccessful euploid transfers, finding that female age had no impact, while BMI, embryo quality and the type of FET used did.
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.
