Key Takeaways

IVF Delivery Rates by Age: 35 Years of Progress

Women under 35 now achieve a 57% delivery rate per embryo transfer (up from 32% in 1993), while those aged 35-40 see 43%. This reflects lab techniques, blastocyst culture, and single embryo transfers reducing multiples while boosting implantation success.

Preimplantation Genetic Testing: Enhancing IVF Success

Preimplantation genetic screening (PGT) identifies aneuploid embryos, reducing miscarriage rates and improving implantation chances. This technology allows clinics to select genetically normal embryos for transfer, directly correlating with higher live birth outcomes.

Vitrification Advancements in Frozen Embryo Transfers

The vitrification technique, adopted by Shady Grove in 2009, revolutionized cryopreservation. Michael Tucker’s 1997 first U.S. frozen egg birth paved the way for this method, which now ensures survival rates for frozen eggs/embryos equal to fresh cycles, with 70% of good-prognosis patients opting for single transfers.
