3 Biggest Reasons For Frozen Embryo Transfer Success

Frozen embryo implantation and pregnancy rates have improved drastically in the past few years. Three important developments are responsible for this improvement.


Rapid embryo cryopreservation or vitrification, which freezes the embryo rapidly,keeps them as good as, and possibly even better than, fresh embryos. The new, rapid freezing process avoids intracellular ice formation with more than 90% of pre-vitrified embryos surviving.


The second important development was to cryopreserve blastocysts rather than day 2-3 embryos. Implantation and pregnancy rates could be markedly improved by selectively transferring expanded blastocysts. So lesser embryos need to be transferred, reducing the incidence of high order multiple pregnancy.


Preimplantation genetic testing (PGT) using methods such as Array Comparative Genomic Hybridization (aCGH) allows for identification of healthy embryos that contain normal chromosomes. Combining PGT with embryo freezing improves the efficiency of embryo transfer. It also reduces the risk of miscarriage and chromosomal birth defects. This embryo banking can reduce the otherwise adverse effect of the advancing biological clock,in older women and women with diminishing ovarian reserve.

A typical Frozen Embryo Transfer (FET) process includes –

  • Lab tests (all routine labs through two pregnancy tests)
  • Thawing and processing of embryo(s)
  • Embryo transfer
  • Assisted Hatching
