Treatments
Embryo freezing and genetic testing
Vitrification, frozen transfer and PGT.
Vitrification freezes embryos in seconds, avoiding the ice crystals of older methods, so survival after thawing is now high. A frozen transfer can be gentler and is often just as successful. Preimplantation genetic testing (PGT) checks embryos before transfer when it is indicated.
- PGT-A checks the number of chromosomes
- PGT-M checks for a specific inherited condition in the family
- Freezing all embryos is safer where there is a risk of OHSS
- Frozen embryos can be stored for future pregnancies
